How does provider work Flutter?

The generics (values inside <> brackets) tell Flutter what type of provider to look for. Then Flutter goes up through the widget tree until it finds the provided value. If the value isn’t provided anywhere then an exception is thrown. Finally, once you’ve got the provider, you can call any method on it.12 Haz 2020
