A Flutter Package for Building Settings Forms

A flutter package for building settings forms. This includes a library of pre-built form field widgets. It supports both Material and Cupertino style.


This package consists of a CardSettings layout wrapper and a series of form field options including:

  • Text Fields
    • CardSettingsText - Basic text field
    • CardSettingsParagraph - Multiline text field with a counter
    • CardSettingsEmail - A text field pre-configured for email input
    • CardSettingsPassword - A text field pre-configured for passwords
    • CardSettingsPhone - A masked phone entry field (US style currently)
  • Numeric Fields
    • CardSettingsDouble - Field for double precision numbers
    • CardSettingsInt - Field for integer numbers
    • CardSettingsCurrency - Field for currency entry
    • CardSettingsSwitch - Field for boolean state
  • Pickers
    • CardSettingsListPicker - Picker list of arbitrary options
    • CardSettingsNumberPicker - Picker list of numbers in a given range
    • CardSettingsRadioPicker - Single items picker with radio buttons
    • CardSettingsSelectionPicker - Single selection from a list with optional icons
    • CardSettingsCheckboxPicker - Select multiples from a list of available options
    • CardSettingsColorPicker - Picker for colors with three flavors: RGB, Material, and Block
    • CardSettingsDatePicker - Date Picker
    • CardSettingsTimePicker - Time Picker
    • CardSettingsDateTimePicker - Combo Date and Time Picker
    • CardSettingsFilePicker - Upload a file from the device
  • Informational Sections
    • CardSettingsHeader - A control to put a header between form sections
    • CardSettingsInstructions - Informational read-only text
  • Actions
    • CardSettingsButton - Actions buttons for the form

All fields support validate, onChange, onSaved, autovalidate, and visible.

The package also includes these additonal items:

  • CardSettingsField - The base layout widget. You can use this to build custom fields
  • Converters - a set of utility functions to assist in converting data into and out of the fields

Simple Example

All fields in this package are compatible with the standard Flutter Form widget. Simply wrap the CardSettings control in a form and use it as you normally would with the form functionality.

  String title = "Spheria";
  String author = "Cody Leet";
  String url = "http://www.codyleet.com/spheria";

  final GlobalKey<FormState> _formKey = GlobalKey<FormState>();

  Widget build(BuildContext context) {
      body: Form(
        key: _formKey,
        child: CardSettings(
          children: <CardSettingsSection>[
              header: CardSettingsHeader(
                label: 'Favorite Book',
              children: <CardSettingsWidget>[
                  label: 'Title',
                  initialValue: title,
                  validator: (value) {
                    if (value == null || value.isEmpty) return 'Title is required.';
                  onSaved: (value) => title = value,
                  label: 'URL',
                  initialValue: url,
                  validator: (value) {
                    if (!value.startsWith('http:')) return 'Must be a valid website.';
                  onSaved: (value) => url = value,

If you would like separate cards for each section, then use the .sectioned constructor:

        child: CardSettings.sectioned(

See the full demo example here.


The style of the widgets can be either Material or Cupertino. There is a toggle on the CardSettings widget to globally change the style:

  return CardSettings(
    showMaterialonIOS: true, // default is false

This also exists on each field widget, in case you want to control this more granularly.

If you are using the Material design style, then the MaterialApp theme takes effect. This example shows what global theme values to set to determine how the various elements appear.

class MyApp extends StatelessWidget {

  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Card Settings Example',
      home: new HomePage(),
      theme: ThemeData(
        primaryColor: Colors.teal, // app header background
        secondaryHeaderColor: Colors.indigo[400], // card header background
        cardColor: Colors.white, // card field background
        backgroundColor: Colors.indigo[100], // app background color
        buttonColor: Colors.lightBlueAccent[100], // button background color
        textTheme: TextTheme(
          button: TextStyle(color: Colors.deepPurple[900]), // button text
          subtitle1: TextStyle(color: Colors.grey[800]), // input text
          headline6: TextStyle(color: Colors.white), // card header text
        primaryTextTheme: TextTheme(
          headline6: TextStyle(color: Colors.lightBlue[50]), // app header text
        inputDecorationTheme: InputDecorationTheme(
          labelStyle: TextStyle(color: Colors.indigo[400]), // style for labels

Or if you want to apply a different theme to the CardSettings hierarchy only, you can wrap it in a Theme widget like so:

    data: Theme.of(context).copyWith(
      primaryTextTheme: TextTheme(
        headline6: TextStyle(color: Colors.lightBlue[50]), // app header text
      inputDecorationTheme: InputDecorationTheme(
        labelStyle: TextStyle(color: Colors.deepPurple), // style for labels
    child: CardSettings(

Please see https://pub.dev/packages/flutter_material_pickers#-readme-tab- for information on how to theme the dialog popups.

Card Style

By default, in Material mode, the content is inside a Card or Cards (if sectioned).


If you would rather just have a flat style with no border, set cardless to false.


  return CardSettings(
    cardless: true; // default is false

This has no effect in Cupertino mode, as that doesn't have a card to begin with.

You can also change the actual card styleing through the theme for example:


  cardTheme: CardTheme(
    shape: RoundedRectangleBorder(
      side: BorderSide(width: 2, color: Colors.orange),
      borderRadius: BorderRadius.circular(20),

Global Properties

The CardSettings widget implements a few global settings that all child fields can inherit. Currently it supports only label customization.


You can control how the labels are rendered with four properties:

    labelAlign: TextAlign.right, // change the label alignment
    labelWidth: 120.0, // change how wide the label portion is
    labelSuffix: ':', // add an optional tag after the label
    labelPadding: 10.0, // control the spacing between the label and the content
    contentAlign: TextAlign.left, // alignment of the entry widgets
    icon: Icon(Icons.person), // puts and option icon to the left of the label
    requiredIndicator: Text('*', style: TextStyle(color: Colors.red)), // puts an optional indicator to the right of the label

The labelAlign and contentAlign properties are also available on each field, so you can override the global setting for individual fields.

    label: 'Last Name',
    labelAlign: TextAlign.left,
    contentAlign: TextAlign.right,


CardSettingsHeader provides properties to set the color, height, and label alignment. However, if you wish to completely override the default header style and replace it with something custom, you can use the child property to pass in your own widget tree:

header: CardSettingsHeader(
  child: Container(
    height: 80,
    child: Row(
      children: [
        Expanded(child: Divider(color: Colors.purple, thickness: 5)),
        Text('Custom Header', style: TextStyle(fontSize: 20)),
        Expanded(child: Divider(color: Colors.purple, thickness: 5)),

Dynamic Visibility

Each field implements a visible property that you can use to control the visibility based on the value of other fields. In this example, the switch field controls the visibility of the text field:

  bool _ateOut = false;

    label: 'Ate out?',
    initialValue: _ateOut,
    onChanged: (value) => setState(() => _ateOut = value),

    label: 'Restaurant',
    visible: _ateOut,


The CardSettingsText widget has an inputMask property that forces entered text to conform to a given pattern. This is built upon the flutter_masked_text package and as such masks are formatted with the following characters:

  • 0: accept numbers
  • A: accept letters
  • @: accept numbers and letters
  • *: accept any character

So for example, phone number would be '(000) 000-0000'.

Note: CardSettingsPhone is a convenience widget that is pre-configured to use this pattern.

Caution: flutter_masked_text is a controller and as such, you will not be able to use an inputMask and a custom controller at the same time. This might be rectified in the future.


This suite allows for orientation switching. To configure this, build different layouts depending on the orientation provided by MediaQuery.

You might want to have different fields in each layout, or a different field order. So that Flutter doesn't get confused tracking state under this circumstance, you must provide a unique state key for each individual field, using the same key in each layout.

Widget build(BuildContext context) {

  final GlobalKey<FormState> _emailKey = GlobalKey<FormState>();
  var orientation = MediaQuery.of(context).orientation;

  return Form
    key: _formKey,(
    child: (orientation == Orientation.portraitUp)
        ? CardSettings(children: <Widget>[
              // Portrait layout here
              CardSettingsEmail(key: _emailKey)
        : CardSettings(children: <Widget>[
              // Landscape layout here
              CardSettingsEmail(key: _emailKey)

You may have multiple fields on the same row in landscape orientation. This normally requires the use of container widgets to provide the layout inside the row. Instead, you can use the CardFieldLayout helper widget to streamline this. It will by default make it's children equally spaced, but you can provide an array of flex values to control the relative sizes.

// equally spaced example
  children: <Widget>[
    CardFieldLayout(children: <Widget>[
// relative width example
  children: <Widget>[
      children: <Widget>[
      flexValues: [2, 1], // 66% and 33% widths

Custom Fields

The CardSettingsField is the basis of all other fields and can be used to build unique fields outside of this library. Its purpose is to govern layout with consistent decorations. The best way to make a custom field is to inherit from FormField<T>, which will manage the state of your field. The cleanest example of this is the CardSettingsSwitch widget. All you have to do is provide your custom widgets in the content property.

Custom Widgets

If you wish to provide a custom widget that is not a field type layout, you need to implement the CardSettingsWidget interface as so:

class CardSettingsHeader extends StatelessWidget implements CardSettingsWidget {




This widget set relies on these external third-party components:

A Simple Wrapper Around Amplify AppSync Simulator

This serverless plugin is a wrapper for amplify-appsync-simulator made for testing AppSync APIs built with serverless-appsync-plugin.


npm install serverless-appsync-simulator
# or
yarn add serverless-appsync-simulator


This plugin relies on your serverless yml file and on the serverless-offline plugin.

  - serverless-dynamodb-local # only if you need dynamodb resolvers and you don't have an external dynamodb
  - serverless-appsync-simulator
  - serverless-offline

Note: Order is important serverless-appsync-simulator must go before serverless-offline

To start the simulator, run the following command:

sls offline start

You should see in the logs something like:

Serverless: AppSync endpoint: http://localhost:20002/graphql
Serverless: GraphiQl: http://localhost:20002


Put options under custom.appsync-simulator in your serverless.yml file

| option | default | description | | ------------------------ | -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | | apiKey | 0123456789 | When using API_KEY as authentication type, the key to authenticate to the endpoint. | | port | 20002 | AppSync operations port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20002, 20012, 20022, etc.) | | wsPort | 20003 | AppSync subscriptions port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20003, 20013, 20023, etc.) | | location | . (base directory) | Location of the lambda functions handlers. | | refMap | {} | A mapping of resource resolutions for the Ref function | | getAttMap | {} | A mapping of resource resolutions for the GetAtt function | | importValueMap | {} | A mapping of resource resolutions for the ImportValue function | | functions | {} | A mapping of external functions for providing invoke url for external fucntions | | dynamoDb.endpoint | http://localhost:8000 | Dynamodb endpoint. Specify it if you're not using serverless-dynamodb-local. Otherwise, port is taken from dynamodb-local conf | | dynamoDb.region | localhost | Dynamodb region. Specify it if you're connecting to a remote Dynamodb intance. | | dynamoDb.accessKeyId | DEFAULT_ACCESS_KEY | AWS Access Key ID to access DynamoDB | | dynamoDb.secretAccessKey | DEFAULT_SECRET | AWS Secret Key to access DynamoDB | | dynamoDb.sessionToken | DEFAULT_ACCESS_TOKEEN | AWS Session Token to access DynamoDB, only if you have temporary security credentials configured on AWS | | dynamoDb.* | | You can add every configuration accepted by DynamoDB SDK | | rds.dbName | | Name of the database | | rds.dbHost | | Database host | | rds.dbDialect | | Database dialect. Possible values (mysql | postgres) | | rds.dbUsername | | Database username | | rds.dbPassword | | Database password | | rds.dbPort | | Database port | | watch | - *.graphql
- *.vtl | Array of glob patterns to watch for hot-reloading. |


    location: '.webpack/service' # use webpack build directory
      endpoint: 'http://my-custom-dynamo:8000'


By default, the simulator will hot-relad when changes to *.graphql or *.vtl files are detected. Changes to *.yml files are not supported (yet? - this is a Serverless Framework limitation). You will need to restart the simulator each time you change yml files.

Hot-reloading relies on watchman. Make sure it is installed on your system.

You can change the files being watched with the watch option, which is then passed to watchman as the match expression.


      - ["match", "handlers/**/*.vtl", "wholename"] # => array is interpreted as the literal match expression
      - "*.graphql"                                 # => string like this is equivalent to `["match", "*.graphql"]`

Or you can opt-out by leaving an empty array or set the option to false

Note: Functions should not require hot-reloading, unless you are using a transpiler or a bundler (such as webpack, babel or typescript), un which case you should delegate hot-reloading to that instead.

Resource CloudFormation functions resolution

This plugin supports some resources resolution from the Ref, Fn::GetAtt and Fn::ImportValue functions in your yaml file. It also supports some other Cfn functions such as Fn::Join, Fb::Sub, etc.

Note: Under the hood, this features relies on the cfn-resolver-lib package. For more info on supported cfn functions, refer to the documentation

Basic usage

You can reference resources in your functions' environment variables (that will be accessible from your lambda functions) or datasource definitions. The plugin will automatically resolve them for you.

      Ref: MyBucket # resolves to `my-bucket-name`

      Type: AWS::DynamoDB::Table
        TableName: myTable
      Type: AWS::S3::Bucket
        BucketName: my-bucket-name

# in your appsync config
    name: dynamosource
        Ref: MyDbTable # resolves to `myTable`

Override (or mock) values

Sometimes, some references cannot be resolved, as they come from an Output from Cloudformation; or you might want to use mocked values in your local environment.

In those cases, you can define (or override) those values using the refMap, getAttMap and importValueMap options.

  • refMap takes a mapping of resource name to value pairs
  • getAttMap takes a mapping of resource name to attribute/values pairs
  • importValueMap takes a mapping of import name to values pairs


      # Override `MyDbTable` resolution from the previous example.
      MyDbTable: 'mock-myTable'
      # define ElasticSearchInstance DomainName
        DomainEndpoint: 'localhost:9200'
      other-service-api-url: 'https://other.api.url.com/graphql'

# in your appsync config
    name: elasticsource
      # endpoint resolves as 'http://localhost:9200'
          - ''
          - - https://
            - Fn::GetAtt:
                - ElasticSearchInstance
                - DomainEndpoint

Key-value mock notation

In some special cases you will need to use key-value mock nottation. Good example can be case when you need to include serverless stage value (${self:provider.stage}) in the import name.

This notation can be used with all mocks - refMap, getAttMap and importValueMap

      Fn::ImportValue: other-service-api-${self:provider.stage}-url

      - key: other-service-api-${self:provider.stage}-url
        value: 'https://other.api.url.com/graphql'


This plugin only tries to resolve the following parts of the yml tree:

  • provider.environment
  • functions[*].environment
  • custom.appSync

If you have the need of resolving others, feel free to open an issue and explain your use case.

For now, the supported resources to be automatically resovled by Ref: are:

  • DynamoDb tables
  • S3 Buckets

Feel free to open a PR or an issue to extend them as well.

External functions

When a function is not defined withing the current serverless file you can still call it by providing an invoke url which should point to a REST method. Make sure you specify "get" or "post" for the method. Default is "get", but you probably want "post".

        url: http://localhost:3016/2015-03-31/functions/addUser/invocations
        method: post
        url: https://jsonplaceholder.typicode.com/posts
        method: post

Supported Resolver types

This plugin supports resolvers implemented by amplify-appsync-simulator, as well as custom resolvers.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.


If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.


A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.


New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making.

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).


Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.


Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
