VxStore

This is where all the in-memory data of your app is stored. Mutations fetch data from APIs, databases etc. and keep it here.

class AppStore extends VxStore {
  int count = 0;
}

You can have only a single store in the app. If you want to divide the store, you can create more models and add their instances to this class. For example:

class EcommerceStore extends VxStore {
  final cart = Cart()

  final orders = Orders();

  final profile = Profile();
}

Reason for using a single store:

Single source of truth
Easily persist store by serializing it
Jump between different instances of store like Redux time travel

Initialization

You can attach store to your app like this:

void main() {
  runApp(VxState(
    store: AppStore(),
    child: MyApp(),
  ));
}

This is essentially a global variable which means you should be a little bit careful while writing tests. You should not keep reference to store instance. Access should be restricted only though VxState.store getter, like below, to avoid some common mistakes.

AppStore store = VxState.store;
