To build an APK (Android Package Kit) in Flutter, you can follow these steps:
Open your Flutter project in your code editor of choice (like VS Code, or Android Studio).
Ensure that your project is set up to build for Android. You can check this by looking at the Android folder in your project directory. If it doesn’t exist, you may need to run the Flutter create command to create it.
Open a terminal in the root directory of your Flutter project.
Run the command flutter build apk. This will build the APK for your project.
flutter build apk --release
Once the build process completes, you can find the APK file in the build/app/outputs/flutter-apk directory.
