Random out of memory issues iOS

[vanlooverenkoen]

Sometimes we can use our app for 30 min
Sometimes the app crashes after 1 min

Could be related to the flutter engine that is used in the native iOS code

If the background channel never receives an initialized result. The resources of the flutter engine would not be destroyed. Causing a out of memory crash

[vanlooverenkoen]

Always double check that your callback function does not trigger a crash before the method channel is setup. This could lead to out of memory issues. becaus native code is never notified that the callback is initialized

typical setup:

Future<void> callbackHandler() async {
  _setupFlavorValues();
  await setupBackgroundDriverDependencyTree();
  BackgroundLocationTrackerManager.handleBackgroundUpdated((data) => KiwiContainer().resolve<YourRepo>().updateBackgroundLocation(data));
}

Scenario where out of memory errors would occur

Future<void> callbackHandler() async {
  _setupFlavorValues(); //throws error
  await setupBackgroundDriverDependencyTree(); //is never called
  BackgroundLocationTrackerManager.handleBackgroundUpdated((data) => KiwiContainer().resolve<YourRepo>().updateBackgroundLocation(data)); //is never called
}
