Flutter Using Multiple Models with Scoped Model

Question

I'm trying to build an Expense tracker App in Flutter and has decided to use Scoped Model for state management. The App has a User who can have many Accounts and each account can have many Transactions.

How do I model these to be used with Scoped Model, I am stuck on selecting a good Architecture.

If I create a UserModel that has a list of Accounts where each Account is an AccountModel then triggering and update from inside AccountModel would not trigger the ones accessing the UserModel class.

Answer 1

class CombinedWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final username =
      ScopedModel.of<UserModel>(context, rebuildOnChange: true).username;
    final counter =
      ScopedModel.of<CounterModel>(context, rebuildOnChange: true).counter;

    return Text('$username tapped the button $counter times');

  }
}

you can see complete example in source .
