如何删除scoped_model状态？

Question

I am use scoped_model for handle app state but I need to wipe all stored state (for example on user sign out).

How to delete all state store in scoped_model ?

I know can just set state value to null. For example:

var = null

But this difficult to maintain if add new variable to state in scoped_model .

I am look for easy way to do.

UPDATE:

Example code store state:

First declare bool: bool isUserRegister;

Then set isUserRegister = true; after check database.

I have many of this type store in scoped_model . I need simple way to delete all state.

I am initialize model at top of widget hierarchy and wrap MaterialApp in ScopedModel :

void main() {
  runApp(new ExampleApp());
}

class ExampleApp extends StatelessWidget {

    final ExampleModel exampleModel = ExampleModel();

    //...

        return ScopedModel<ExampleModel>(
            model: exampleModel,
            child: MaterialApp(

Maybe one way is to initialize the model again?

Answer 1

You can create a method in your state class (the one that extends the Model class) that sets all your objects to null/empty arrays. It's hard to provide a certain answer given that you didn't provide any code to us.

Let's say that's your model:

class ExampleModel extends Model {
  String _someString = "some value";
  bool _someBool = false;

  void clear() {
    _someState = null;
    _someBool = null;
  }
}

You can just create a method like clear() and call it whenever you like.
