Pueprint: A Flutter Package to Make Streams and Single Pages

💩 Pueprint 💩

What am I?

A Flutter package to make flows and single pages much easier to lay out and style.

Why Pueprint? Because it stands for Page + Blueprint, which combines to 💩Pueprint💩!

Motivation

Flows usually consist of several pages that have an AppBar as well as some sort of Footer which allows the user to proceed to through the flow. However, these AppBar and Footer widgets are commonly overlayed on top of each page and are located in parent component, which makes it tedious to tweak these widgets without a bunch of boilerplate and lifting state up.

This package makes it easy to:

  • Declaratively customize each page in a flow without sacrificing styling capabilities
  • Support for easily changing progress bars and page indicators through a flow
  • Change onTap behaviours on each page
  • Render pages based on screen size
  • Integrate with any routing libraries (like AutoRoute, VRouter, Routemaster, etc.)
  • coming soon Animate AppBars and Footers when changing between pages
  • ..and more..

All with minimal boilerplate and code.

In addition to flows, this package provides a simple page blueprint that allows you to easily add AppBars, Footers and Headers to pages.

Getting Started

Install this package in your pubspec.yaml file.

dependencies:
  pueprint: [latest-version]

and import with

import 'package:pueprint/pueprint.dart';

Using this package

For Flows

  1. Define your parent Pueprint widget for your descendant flow pages. Think of the Pueprint as a scaffold for your child pages.
  Widget build(BuildContext context) {
    return Pueprint(
      appBarBuilder: (context, state) {
        return AppBar(
          leading: IconButton(
            icon: Icon(state.icon),
            onPressed: state.onTapLeading,
          )
        );
      },
      footerBuilder: (context, state) {
        return PueFooter(
          child: ElevatedButton(
            child: state.buttonChild,
            onPressed: state.onTap,
          ),
          bottom: AnimatedSmoothIndicator(
            activeStep: state.activeStep,
            count: 3,
          )
        );
      },
      body: DescendantPages(), // See the very bottom of this readme for examples
      // on integrating descendant pages with popular routing libraries such as
      // AutoRoute and VRouter
    );
  }
  1. Now in your flow pages, use PuePage to easily change your appBar and footer behaviour
  @override
  Widget build(BuildContext context) {
    return PuePage(
      appBarData: AppBarData(
        onTapLeading: () => context.router.pop(),
        icon: Icons.back_arrow_ios,
      ),
      footerData: FooterData(
        onTap: () => handleGoToNextPage(),
        buttonChild: Text('Submit'),
        activeIndex: 1,
      ),
      body: MyPageBody(),
    );
  }

Everytime you move to a new page in the flow, call the PuePage widget to update your app bar and footer!

Outside of Flows

If you would like to use the the layout capabilities of this library, first place a PueProvider at the top of your widget tree.

  PueProvider(
    child: DescendantWidgets(),
    theme: PueTheme(), // if you want to customize the theme of your Pue widgets
  );

Now, use SoloPuePage like so:

SoloPuePage(
  appBar: AppBar(),
  header: PueHeader(text: "I love me some poo"),
  body: PueBody(
    child: Text("More poo"),
    listView: true,
  ),
  footer: PueFooter(
    floating: true,
    child: ElevatedButton(
      child: Text("Generate poo!"),
      onPressed: () => plopItOut(),
    )
  ),
)

Core concepts

This package revolves around the idea that a page can be divded into 4 distinct parts:

This package uses these 4 distinct elements to draw a page.

Widgets

Pueprint

The Pueprint widget is used as the wrapper for all pages in a flow. It is responsible for actually rendering the app bar and footer in a flow.

PuePage

The PuePage widget is used in all of the descendant flow pages of a parent Pueprint. You can declaratively define attributes of the app bar and footer here, and it will automatically update the corresponding fields of the app bar and footer which is being rendered in the parent Pueprint.

SoloPuePage

For pages that are not a part of flows, but you still want to access the layout capabilities in this package. You can set all 4 core areas of a page in this widget.

Integration with Routing Libraries

A flow UI and UX package wouldn't be complete without understanding how it can be integrated with navigation, since these features go hand-in-hand. Here are some examples of how to use this package in conjunction with some popular routing libraries.

AutoRoute

  1. Define your wrapper page. In this case, we are calling it FlowWrapperPage
class FlowWrapperPage extends StatelessWidget {
  const FlowWrapperPage({Key key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Pueprint(
      appBarBuilder: (context, state) {
        return AppBar(
          leading: IconButton(
            icon: Icon(state.icon),
            onPressed: state.onTapLeading,
          )
        );
      },
      footerBuilder: (context, state) {
        return ElevatedButton(
          child: state.buttonChild,
          onPressed: state.onTap,
        );
      },
      body: AutoRouter(),
    );
  }
}
  1. Plug your FlowWrapperPage into your routing setup like so
@MaterialAutoRouter(
    replaceInRouteName: 'Page,Route',
    routes: <AutoRoute>[
        // ...your other routes
        AutoRoute(
            path: "/flow",
            page: FlowWrapperPage, // plug your wrapper page in right here!
            children: [
                AutoRoute(path: '1', page: Flow1Page),
                AutoRoute(path: '2', page: Flow2Page),
                AutoRoute(path: '3', page: Flow3Page),
            ],
        ),
    ],
)
class $AppRouter {}
  1. Now in your flow pages use PuePage like so!
class Flow1Page extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return PuePage(
      appBarData: AppBarData(
        onTapLeading: () => context.router.pop(),
        icon: Icons.back_arrow_ios,
      ),
      footerData: FooterData(
        onTap: () => handleGoToNextPage(),
        buttonChild: Text('Submit'),
      ),
      body: MyPageBody(),
    );
  }
}

VRouter

  1. Define your wrapper page. In this case, we are calling it FlowWrapperPage
class FlowWrapperPage extends StatelessWidget {
  final Widget child;

  const FlowWrapperPage({Key key, required this.child}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Pueprint(
      appBarBuilder: (context, state) {
        return AppBar(
          leading: IconButton(
            icon: Icon(state.icon),
            onPressed: state.onTapLeading,
          )
        );
      },
      footerBuilder: (context, state) {
        return ElevatedButton(
          child: state.buttonChild,
          onPressed: state.onTap,
        );
      },
      body: child,
    );
  }
}
  1. Plug your FlowWrapperPage into your routing setup like so
VNester(
 path: '/flow',
 widgetBuilder: (child) => FlowWrapperPage(body: child),
 nestedRoutes: [
    VWidget(path: '1', widget: Flow1Page()),
    VWidget(path: '2', widget: Flow2Page()),
    VWidget(path: '3', widget: Flow3Page()),
 ],
)
  1. Now in your flow pages use PuePage like so!
class Flow1Page extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return PuePage(
      appBarData: AppBarData(
        onTapLeading: () => context.router.pop(),
        icon: Icons.back_arrow_ios,
      ),
      footerData: FooterData(
        onTap: () => handleGoToNextPage(),
        buttonChild: Text('Submit'),
      ),
      body: MyPageBody(),
    );
  }
}

Comments, feedback and questions are much appreciated. Just drop an issue or anything else you might want to drop in the github repo! 💩💩

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add pueprint

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  pueprint: ^0.0.8

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:pueprint/pueprint.dart';

example/lib/main.dart

import 'package:flutter/material.dart';
import 'package:smooth_page_indicator/smooth_page_indicator.dart';

Pueprint: A Flutter Package to Make Streams and Single Pages

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.

sksl_warm-up

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.

flutter_autofill

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.

flutter_DatePicker

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. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

You can get more free Flutter tutorials you can follow these courses:

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-mobile-desktop-web-embedded_min

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.

humming_bird_dart_flutter

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

Dream11

Dream11

NuBank

NuBank

Reflectly app

Abbey Road Studios

Abbey Road Studios

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.

Adobe XD plugin for Flutter with CodePen Tutorial

Recently Adobe XD releases a new version of the plugin that you can use to export designs directly into flutter widgets or screens. Yes, you read it right, now you can make and export your favorite design in Adobe XD and export all the design in the widget form or as a full-screen design, this can save you a lot of time required in designing.

What we will do?
I will make a simple design of a dialogue box with a card design with text over it as shown below. After you complete this exercise you can experiment with the UI. You can make your own components or import UI kits available with the Adobe XD.
