**Lesson 1: Getting Started with Flutter**
**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
– 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.

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.
