Code Setup: Only WorkoutSetScreen

Add the required packages for GOFA Pose SDK

Our GOFA SDK uses GetIt to register our GofaPoseSdkManager as a singleton service helps with initialization of our SDK functionalities.

So please run the following command to add the dependencies

flutter pub add get_it
flutter pub add provider
flutter pub add bloc
flutter pub add flutter_bloc

Starting WorkoutSetScreen directly

ElevatedButton(
  onPressed: () async {
    await registerGofaPoseSdk(
      context: context,
    );
    if (context.mounted) {

          key: 'squats',
          localizedNames: {
            en: "Squats",
            zh_Hant: "深蹲",
            zh_Hans: "深蹲",

  required BuildContext context,

  // final isPhysicalDevice = await checkPhysicalDevice();

  if (!GetIt.I.isRegistered<GofaPoseSdkManager>()) {
    final gofaPoseSDKManager = GofaPoseSdkManager();

    GetIt.I.registerSingleton<GofaPoseSdkManager>(gofaPoseSDKManager);
  }

  final gofaPoseSDKManager = GetIt.I<GofaPoseSdkManager>();

  try {
    if (gofaPoseSDKManager.isInitialized) {
      log.d('GofaPoseSdkManager is already initialized');
      return;

    gofaPoseSDKManager
        .init(); // do not await so that splash screen can be shown
  } catch (e) {
    log.e('Error registering GofaPoseSdkManager: $e');

    // show scaffold messenger
    if (context.mounted) {

          content: Text('Error occurred when starting GofaPoseSdkManager'),
        ),
      );
    }
  }
}

Future<void> navigateToWorkoutSetScreen({

    } on TimeoutException catch (e) {
      log.e('Error initializing GofaPoseSdkManager: $e');

      if (context.mounted) {
        // show scaffold with error message
        ScaffoldMessenger.of(context).showSnackBar(

            // pop one screen
            Navigator.of(context).pop();

          ),
    );

    if (!context.mounted) return;

    // navigate to WorkoutSetScreen
    Navigator.push(
      context,
      MaterialPageRoute(
        builder: (context) => const WorkoutSetScreen(),

Example to get back the result of the last workout

// Show a button "Get last workout result"
ElevatedButton(
  onPressed: () async {
    await registerGofaPoseSdk(
      context: context,
    );
    // wait till GofaPoseSdkManager is initialized
    await GetIt.I<GofaPoseSdkManager>()
        .isInitialized$
        .timeout(const Duration(seconds: 5))
        .contains(true);

    final lastWorkoutSetState = GetIt.I<WorkoutSetBloc>().state;

    log.d('lastWorkoutSetState: $lastWorkoutSetState');

    if (context.mounted) {
      // prompt a widget to show the last workout result
      showDialog(
        context: context,
        builder: (context) {
          return AlertDialog(
            title: const Text('Last Workout Result'),
            content: Text(
                'Workout Item: ${lastWorkoutSetState.workoutItem?.poseName}\n'
                'Reps done: ${lastWorkoutSetState.repsDone}\n'
                'Seconds Used: ${lastWorkoutSetState.secondsUsed}\n'),
            actions: <Widget>[
              TextButton(
                onPressed: () {
                  Navigator.of(context).pop();
                },
                child: const Text('Close'),
              ),
            ],
          );
        },
      );
    }
  },
  child: const Text('Get last workout result'),
),

Add Gofa Pose SDK language support

Since version v2.0.0, the locales of our supported languages are:

Locale('en'),
Locale.fromSubtags(languageCode: 'zh', scriptCode: 'Hant'),
Locale.fromSubtags(languageCode: 'zh', scriptCode: 'Hans'),

You are required to add GofaLocalizationsDelegate() to the localizationsDelegates array list of your MaterialApp.

MaterialApp(
  ...
  localizationsDelegates: const [
    AppLocalizations.delegate,
    ...
    GofaLocalizationsDelegate(),
  ],
  locale: currentLocale,
  supportedLocales: yourSupportedLocales,
  // supportedLocales: GofaLocalizations.supportedLocales,
  ...
)
