 **Lesson 1: Getting Started with Flutter**

Mobile App Development

**1. What is Flutter?**

– Flutter is an open-source UI software development toolkit created by Google.
– It allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase.

**2. Advantages of Flutter:**

– **Single Codebase:** Write once, run on both iOS and Android.
– **Hot Reload:** See changes instantly without fully restarting the app.
– **Rich Widgets:** A vast collection of customizable widgets for creating complex UIs.

**3. Installing Flutter:**

*Note: Before installing Flutter, make sure you have Git installed on your machine.*

a. **For macOS**:
– Download the latest stable Flutter SDK from the official [Flutter website](https://flutter.dev/docs/get-started/install/macos).
– Extract the file and add it to your PATH.

b. **For Windows**:
– Download the Flutter SDK from the official [Flutter website](https://flutter.dev/docs/get-started/install/windows).
– Extract the zip file and place the contained flutter in the desired installation path.
– Add the path to your environment variables.

c. **For Linux**:
– Follow instructions on the official [Flutter website](https://flutter.dev/docs/get-started/install/linux).

**4. Verify Installation**:
– Open a terminal or command prompt.
– Run the command: `flutter doctor`
– This tool checks for any dependencies you still need to install. Follow any prompts or recommendations to complete the setup.

**5. Setting Up an Emulator**:

– **Android**: You can use the Android Studio’s AVD Manager to set up an Android emulator.
– **iOS (macOS only)**: Use Xcode to set up an iOS simulator.

**6. Your First Flutter App**:

– In your terminal or command prompt, run:

flutter create my_first_app
cd my_first_app
flutter run

– This will create and run a new Flutter app. If set up correctly, you’ll see a sample app on your emulator.

1. Install Flutter on your machine.
2. Set up an emulator for Android or iOS.
3. Create and run your first Flutter app.

Stay tuned for our next lesson where we’ll dive deeper into Flutter’s widget-based architecture and start building our first custom app!

Note: This tutorial assumes a basic understanding of programming concepts. If you’re an absolute beginner, it might be helpful to review some fundamental programming concepts before delving into Flutter.
