Lets Start Our Code

In flutter mainly we are importing to libraries one is cupertino.dart and material.dart. the first one is for Ios app and second one is Android app.

package:flutter/cupertino.dart'

Here we use material.dart.which include may widgets materialapp , statefull and stateless etc..

The sample Code given below:

package:flutter/material.dart
void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter',
      home: Scaffold(
        appBar: AppBar(
          title:  Text(' Our Project'),
        ),
        body:  Center(
          child: Text('HELLO'),
        ),
      ),
    );
  }

}

void main() -it is the main method \ function of our project.

Scaffold -It is from the Material library, It provides app bar, and a body which contain homescreen.

title - which give title of our app.
center - which is widget which give the text in the center of the screen.
