How to build a Flutter application for BlackBerry?

Flutter officially does not support the BlackBerry 10 OS platform or the BlackBerry 10 Native SDK. Building a Flutter application for BlackBerry devices with this operating system is not possible with standard tools.

BlackBerry Limited has shifted to using Android for its later devices (e.g., BlackBerry KEYone, KEY2). For such devices running on Android OS, building a Flutter application is done as for a standard Android device.

For BlackBerry devices on Android (e.g., KEYone, KEY2):

1. Install the Flutter SDK as described in the official documentation (for your operating system, e.g., Windows, macOS, Linux).
2. Set up Android Studio and SDK, including platform tools and the appropriate Android SDK version.
3. Connect the BlackBerry Android device to your computer and enable USB debugging (developer settings).
4. Use the commands flutter run or flutter build apk.

# Build debug APK
flutter run

# Build release APK
flutter build apk

or

# Build AppBundle
flutter build appbundle

For devices on BlackBerry 10 OS (e.g., Z10, Q10, Passport):

Flutter is incompatible with BlackBerry 10 OS. There is no direct build or porting of Flutter applications to this platform.
