SwitchStore<S, A> class

A widget that renders different content based on the runtime type of the store's state.

Useful when your state is a sealed class hierarchy and each variant should render a different widget.

Example

SwitchStore<AuthState, AuthAction>(
  store: authStore,
  typeMap: {
    LoggedIn: (context, store) => HomeScreen(store: store),
    LoggedOut: (context, store) => LoginScreen(store: store),
  },
);

Fluent API

SwitchStore(store: store)
  .when<LoggedIn>((ctx, store) => HomeScreen(store: store))
  .when<LoggedOut>((ctx, store) => LoginScreen(store: store));
