Answer 4

I had this problem in a Flutter widget test code. The solution illustrated by the images below is applicable to the Flutter app code as well. Note that my Flutter app is conform to the MVVM architecture using Provider, the reason why MultiProvider is used. The code of the project is available on GitHub My AudioLearn prototype project. Note that the real project will be referenced in the readme file and will available as well since earning money is not what motivates me to develop this application.
