Flutter Mobile Development Tutorial

Flutter is a popular open-source UI software development kit created by Google. It is used to develop natively compiled applications for mobile, web, and desktop from a single codebase. This tutorial will guide you through the basics of Flutter mobile development.

Prerequisites

Before you start, make sure you have the following prerequisites:

Getting Started

To create a new Flutter project, use the following command:

flutter create my_flutter_app

This will create a new directory with all the necessary files to start your Flutter app.

Building Your First Flutter App

Step 1: Open Your Project

Open the project directory in your preferred code editor.

Step 2: Update `main.dart`

Open the lib/main.dart file and replace its content with the following:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo Home Page'),
      ),
      body: Center(
        child: Text('Hello, World!'),
      ),
    );
  }
}

Step 3: Run Your App

To run your app, use the following command:

flutter run

This will launch your Flutter app on the connected device or emulator.
