Usage Documentation not available!

[pishabh625]

I tried all the things to do integrate in app update but it is not working at all. Things i tried:

1. Testing using internal app sharing
2. Added required dependencies
   • released one version of app which having(inAppUpdate package integrated)
   • released higher version of app than previous version(inAppUpdate package integrated) In internal testing.... Issue: After doing all this things i am not getting promt for update inside older version of app.

Please help me if i am missing something or provide usage documentation atleast so that everyone can test the app easily without having any issue.

Thank you

// Function class

  static Future<Either<MainFailures, AppUpdateInfo>> checkAppUpdate() async {
    try {
      if(Platform.isAndroid){
        final info = await InAppUpdate.checkForUpdate();
        return Right(info);
      }
      return const Left(MainFailures.formatExceptionFailure);
    } catch (exception) {
      return appUpdateexceptionHandler(exception);
    }
  }
}

// Repository class
class CheckAppUpdateRepository {
  static Future<Either<MainFailures, AppUpdateInfo>> checkInAppUpdate() async {
    final response = await CheckAppUpdateDataProvider.checkAppUpdate();
    return response.fold((failure) {
      return Left(failure);
