Parabeac-Core converts design files into Flutter code

Parabeac-Core

Parabeac-Core is an open-source repository that converts design files into Flutter code.

How it works

Parabeac-Core is essentially broken up into 3 pieces which you can see in the list or animation below. While most of the magic is in the interpretation engine, you can view more animations & information here.

1. Convert design file into Parabeac design protocol
2. Interpretation Engine

Made up of the Visual, Layout, & Alignment generation services.

3. Generate Flutter code

Parabeac Design Protocol

Parabeac Design Protocol is our way of helping define UI/UX elements within Design Files for cleaner and more succinct code conversion. By adding naming-semantics to elements, symbols, and layer names to the design file, Parabeac-Core is able to identify specific UI elements & override interpretation & generation with a specific implementation.

Visual Generation Service

These are mostly built by a one to one relationship from the Parabeac Design Language into Parabeac Intermediate Nodes. For example, a rectangle in the design language will simply convert to an InheritedContainer.

Layout Generation Service

This service is a bit more interesting, as we break down each group of nodes to be laid out by the layout service. The service takes the first 2 nodes compares them & generates a layout, we grab the next node, compare it to the layout & then the leaves if needed to and continuously traverse the rest of the layer into the laid out tree that we construct.

Alignment Generation Service

In Flutter, there are only a couple ways to achieve alignment. We recognized the following as the most common:

• Flex-based layouts
• Padding/margin
• Positioning (Stacks)
• Alignment (Container/Single Child/Visual Node)

Depending on the type of layout to add alignment to we have various services to take the nodes in and apply the alignment information needed.

Get Started

Parabeac currently supports conversions from Sketch but is designed to support more platforms in the future.

Dependencies

• Dart
• Flutter
• node.js

To test out a Sketch file feel free to download this Sketch file!

Cloning the Repo

Because parabeac-core contains the Sketch-Asset-Converter submodule, it is easier to clone the repo using the following command:

git clone --recurse-submodules https://github.com/Parabeac/Parabeac-Core.git

If you have already cloned the repo without the submodule, simply run the following command which will add Sketch-Asset-Converter:

git submodule update --init

In order to pull new changes from the repository, run the following command to also update the submodule:

git pull --recurse-submodules

For more information about git submodules, click here.

Running the conversion

Follow these steps in order to run Parabeac Core on your local environment:

1. Clone PBCore repo in order to get the code on your machine
2. If you have any plugins make sure to put the plugins in the plugin folder
3. In your terminal change directory to the root PBCore directory and run:

 $dart parabeac.dart -p <Absolute Path To Design File> -n <ProjectName> 

Running the exported code

Requirement(s)

• Download Flutter
• Traverse to main.dart
• Call the screen you want to view
• Execute flutter run

How to contribute

Welcome! The best way to contribute to Parabeac is through pull requests, filing issues on Github, writing documentation & helping others in our Discord community. We are an early project, but like many other projects, helping with bugs that others have filed on Stack Overflow is extremely helpful. We recommend filing bugs & feature requests on the Github issue tracker. For more details make sure to check out our wiki.

How to create & run Parabeac eggs

Parabeac eggs are essentially plugins that change the way a set of design elements are interpreted. A very simple example of this are 2 eggs that we created called NavBar & TabBar. Eggs are loaded into the project before the runtime of Parabeac-Core because unfortunately dart doesn’t support dynamic module loading.

You can also create your own eggs! By using our Parabeac Egg Template you can quickly define your own semantics and corresponding code generation which allows for the most flexible and robust export customization possible. You can also upload your eggs to our git-based marketplace for templates to help support the community going forward.

To add a Parabeac egg, download the egg and add it to the parabeac-core/plugins folder. When you run Parabeac-Core it will automatically grab & import the egg into the project.

Upcoming & Known Issues

• Plugin Duplication in the Plugin Service
• Support for Figma
• Egg Marketplace

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 RangeSlider, DatePicker 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. 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.

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

Dream11

NuBank

Reflectly app

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.

jQuery Ajax CRUD in ASP.NET Core MVC with Modal Popup

In this article, we’ll discuss how to use jQuery Ajax for ASP.NET Core MVC CRUD Operations using Bootstrap Modal. With jQuery Ajax, we can make HTTP request to controller action methods without reloading the entire page, like a single page application.

To demonstrate CRUD operations – insert, update, delete and retrieve, the project will be dealing with details of a normal bank transaction. GitHub repository for this demo project : https://bit.ly/33KTJAu.

Sub-topics discussed :

• Form design for insert and update operation.
• Display forms in modal popup dialog.
• Form post using jQuery Ajax.
• Implement MVC CRUD operations with jQuery Ajax.
• Loading spinner in .NET Core MVC.
• Prevent direct access to MVC action method.

Create ASP.NET Core MVC Project

In Visual Studio 2019, Go to File > New > Project (Ctrl + Shift + N).

From new project window, Select Asp.Net Core Web Application_._

Once you provide the project name and location. Select Web Application(Model-View-Controller) and uncheck HTTPS Configuration. Above steps will create a brand new ASP.NET Core MVC project.

Setup a Database

Let’s create a database for this application using Entity Framework Core. For that we’ve to install corresponding NuGet Packages. Right click on project from solution explorer, select Manage NuGet Packages_,_ From browse tab, install following 3 packages.

Now let’s define DB model class file – /Models/TransactionModel.cs.

public class TransactionModel
{
    [Key]
    public int TransactionId { get; set; }

    [Column(TypeName ="nvarchar(12)")]
    [DisplayName("Account Number")]
    [Required(ErrorMessage ="This Field is required.")]
    [MaxLength(12,ErrorMessage ="Maximum 12 characters only")]
    public string AccountNumber { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Beneficiary Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BeneficiaryName { get; set; }

    [Column(TypeName ="nvarchar(100)")]
    [DisplayName("Bank Name")]
    [Required(ErrorMessage = "This Field is required.")]
    public string BankName { get; set; }

    [Column(TypeName ="nvarchar(11)")]
    [DisplayName("SWIFT Code")]
    [Required(ErrorMessage = "This Field is required.")]
    [MaxLength(11)]
    public string SWIFTCode { get; set; }

    [DisplayName("Amount")]
    [Required(ErrorMessage = "This Field is required.")]
    public int Amount { get; set; }

    [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
    public DateTime Date { get; set; }
}

C#Copy

Here we’ve defined model properties for the transaction with proper validation. Now let’s define  DbContextclass for EF Core.

#asp.net core article #asp.net core #add loading spinner in asp.net core #asp.net core crud without reloading #asp.net core jquery ajax form #asp.net core modal dialog #asp.net core mvc crud using jquery ajax #asp.net core mvc with jquery and ajax #asp.net core popup window #bootstrap modal popup in asp.net core mvc. bootstrap modal popup in asp.net core #delete and viewall in asp.net core #jquery ajax - insert #jquery ajax form post #modal popup dialog in asp.net core #no direct access action method #update #validation in modal popup
