What is Angular Dart in Flutter?

Dart supports programming paradigms like Classes, Polymorphism, Interfaces, Inheritance, Collections, and Generics. Dart is developed by Google and is used in building applications and servers. If you are a beginner & want to implement Dart code online before downloading its dependencies, go to https://dartpad.dev/?id. But If you want to implement code on your system, install the Dart SDK from its official website https://dart.dev/tools/sdk/archive.

Code in Dart:

void main() {  
    var info = "article";  
    var publisher = "Welcome to Flutter Agency";  
    print("This $info is published on $publisher");  
}

Output:

This article is published on Welcome to Flutter Agency.

In the above code:

  • void: The void is a return type that indicates that the function does not have a return value.
  • main(): The main() function indicates the beginning of the program and is essential for its execution.
  • var: The var statement declares a variable and it can contain letters, digits, or symbols.
  • print(): You can use the print() function to print output on the console.

AngularDart:

AngularDart is a framework developed by Google for building web applications, server applications, or single-page applications using HTML, CSS, and Dart. It is commonly known for its good speed, execution, and productivity.

AngularJS is a famous tool for making structured web applications and AngularDart is basically an implementation of Angular in Dart Language. The current version of AngularDart is 5.3.1 and is being used in many applications like Fiber, Google Play Console, etc.

How to Run AngularDart Code Online:

If you are a beginner and want to test your AngularDart code online, follow these steps:

1) So, first open DartPad

2) After that click on New Pad.

3) When the confirmation box appears, click OK.

4) Select Dart and Toggle HTML switch ON and click on Create.

5) So, now You can Write the Dart, HTML, and CSS code, and to run the code, click on the Run button.

Below is the AngularDart Code implementation:

Dart:

import 'dart:html';

void main() {
  var header = querySelector('#header');
  header.text = "Geeks for Geeks ";
}

HTML:

<center>
  <h1 id="header"></h1>
  <h2>is best</h2>
</center>

CSS:

body {
  display: flex;
  flex-direction: column;
  background-repeat: no-repeat;
  background-size: cover;
  background-image: url(
    "https://flutteragency.com/wp-content/themes/bosc/assets/images/logo-white.svg")
}

h1 {
  color: black;
  font-family: Arial, Helvetica, sans-serif;
}

h2 {
  color: black;
  font-family: Arial, Helvetica, sans-serif;
}

In the above code:

  • We imported ‘dart:html’ for the required library in the Dart file.
  • Moreover, in the main method, we declared the variable as “header”.
  • Variable picked up the value using querySelector.
  • Also, we assigned the header variable a text to use in HTML.
  • In the HTML file, we called the header value using id as the parameter.
  • In the CSS file, we styled the elements as per our needs.

  • AngularDart Tutorials are hard to find.
  • Less Active AngularDart Community.
  • Angular components package does not support Internet Explorer.
  • Less Popular and it is not as up-to-date as Angular Typescript.
