yx_scope_flutter

yx_scope_flutter package is an adapter for yx_scope package for using it with Flutter.

Features

ScopeProvider is an InheritedWidget that passes your scope down to any widget in the subtree.

ScopeBuilder handles building a widget in response to scope.

ScopeListener is a widget that should be used for functionality that needs to occur only in response to a scope change such as navigation, showing a SnackBar, showing a Dialog, etc...

ScopeConsumer is analogous to a nested ScopeListener and ScopeBuilder but reduces the amount of boilerplate needed.

Usage

Lets take a look at how to use ScopeProvider to provide RootScopeHolder and react to scope changes with ScopeBuilder

1. Create instance of RootScopeHolder and run app

void main() {
  final rootScopeHolder = RootScopeHolder();
  rootScopeHolder.create();
  runApp(App(scopeHolder: rootScopeHolder));
}

2. Use ScopeProvider to provide RootScopeContainer

class App extends StatelessWidget {
  final RootScopeHolder scopeHolder;

  const App({required this.scopeHolder, super.key});

  @override
  Widget build(BuildContext context) {
    return ScopeProvider<RootScopeContainer>(
      holder: scopeHolder,
      child: MaterialApp(
        title: 'YxScopedFlutter Demo',
        home: const HomePage(),
      ),
    );
  }
}

3. Use ScopeBuilder to react to scope changes for build widget

// HomePage widget
//...
Widget build() =>
    ScopeBuilder<RootScopeContainer>.withPlaceholder(
      builder: (context, rootScope) => SomeWidget(rootScope),
      placeholder: const SizedBox.shrink(),
    );
// ...
