Introduction to Flutter

What is Flutter?​

Flutter is an open-source framework created by Google for building mobile, web, and desktop applications using a single codebase. This means you don’t need to write separate code for Android, iOS, or other platforms.

Key Features:​

✅ Uses Dart programming language.
✅ Provides a fast development experience with hot reload (see changes instantly).
✅ Offers beautiful UI widgets for a smooth and native-like experience.

What is Dart?​

Dart is the programming language used in Flutter. It is:

  • Developed by Google.
  • Easy to learn (similar to JavaScript & Java).
  • Fast because it compiles to native machine code.
  • Used for both frontend (UI) and backend (server-side with Dart VM).

Example of Dart Code:

void main() {
  print('Hello, Flutter!');
}

This prints "Hello, Flutter!" to the console.

One Codebase, Multiple Platforms​

With Flutter, you write one set of code, and it runs on:
📱 Android & iOS
💻 Windows, macOS, Linux
🌐 Web (Chrome, Edge, etc.)
📺 Embedded Devices

Instead of learning Swift (iOS) and Kotlin (Android) separately, Flutter lets you build apps for both using Dart!

Setup Flutter​

Follow the official documentation for step-by-step setup:

Creating Fluter App​

To create a new Flutter app, use the following command in your terminal or command prompt:

flutter create my_app

Replace my_app with your desired project name.

Steps to Run the App:​

  1. Navigate into your project folder: 
    cd my_app
  2. Run the app on a connected device or emulator: 
    flutter run
