How to run Flutter App

 Step 1: Open the Flutter Project

Open the folder containing your previous Flutter app project in VS Code. You can do this by clicking on "File" in the menu bar and selecting "Open Folder," then navigating to the project directory and selecting it.

Step 2: Open the Integrated Terminal Open the integrated terminal in VS Code. You can do this by clicking on "View" in the menu bar and selecting "Terminal" or by using the shortcut Ctrl+ backtick (`).

Step 3: Run the Flutter App In the terminal, navigate to the root directory of your Flutter app project. You can use the cd command to change directories. For example, if your project is located in the my_flutter_app directory, use the following command:

bash
cd my_flutter_app

Once you are in the project directory, run the following command to start the app:

arduino
flutter run

This command will build and run your Flutter app on the connected simulator/emulator or physical device.

Step 4: Observe the App Observe the terminal output for any errors or messages related to the app's build process. If everything is successful, the app will launch in the simulator/emulator or on the connected physical device.

Note: Make sure you have a simulator/emulator set up or a physical device connected to your computer before running the app. You can use the Android Emulator or iOS Simulator for testing, or connect a physical device via USB.

That's it! Your previous Flutter app should now be running in the selected environment. You can make changes to your code and the app will automatically update in the simulator/emulator or on the connected device, thanks to Flutter's hot-reload feature.
