Well, that's impossible or at least wrongly designed. You are trying to violate the widget encapsulation and make them directly dependent.

Depends on what exactly you want to achieve that should do the trick:

  1. Wrap all these A, B, C widgets with the provider (you said you are already using provider, but it doesn't mean you provide anything) intro.dart
  2. In C widget consume the provider and call proper method (which would probably update some state)
  3. A widget also consumes the state so it would be re-rendered automatically

If it doesn't solve your current situation - please update the question with exact problem you are facing.
