So that the app would keep all the state of the last seem by the user.

Answer 1

You cannot prevent the operating system from killing your app. iOS kills apps to increase battery life and to free memory.

What you can do is to store some state to the file system with packages like shared_preferences or hive .

If you are using BLoC, you might also find the hydrated_bloc package useful.
