If you want to share the model across different Screens in your app, the ScopedModel
will need to wrap the MaterialApp
or WidgetsApp
. This is because the MaterialApp
creates all screens when you use Navigator.push
etc, and therefore the ScopedModel
needs to be a parent of all screens.
If you only want to use the Model on a Single screen, you can create it in the Root Widget of a Screen (e.g. Home.dart) and all children of that Widget will have access to the ScopedModel.
If you don't want to create the Model until you log in, your MyApp
Widget which creates the MaterialApp
could be a stateful widget. When the login occurs, you could do a setState
on the MyApp
widget with some information about the login and then wrap the MaterialApp
with a scoped model on rebuild if the data exists.
Another way to approach this problem: Create your ScopedModel when the app starts, and use it to drive the login process. This means: When the user logs in, do it with your Model
class -- e.g. call userModel.login(user, pass)
. If it succeeds, update the data in the model and navigate to the home screen (or any screen) and fetch the data from the Model with a ScopedModelDescendant
.
