ReactterScope class
A StatelessWidget that helps to control re-builder of widget tree.
NOTE: The builder callback will be rebuild, when the ReactterContext changes.
For this to happen, the ReactterContext should put it on listens
for BuildContext's watch
ers.
ReactterScope(
build: (context, child) {
final appContext = context.watch<AppContext>();
return Text("AppContext's state: ${appContext.stateHook.state}");
}
)
CONSIDER Use child property to pass a Widget that you want to build it once. The ReactterScope pass it through the builder callback, so you can incorporate it into your build:
ReactterScope(
child: Text("This widget build only once"),
builder: (context, child) {
final appContext = context.watch<AppContext>();
return Column(
children: [
Text("state: ${appContext.stateHook.value}"),
child,
],
);
},
)
