ReactterScope class

A wrapper StatelessWidget that helps to control re-rendered 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 watchers.

ReactterScope(
  build: (context, child) {
    final appContext = context.watch<AppContext>();
    return Text("AppContext's state: ${appContext.stateHook.state}");
  }
)

If you don't want to rebuild a part of builder callback, use the child property, it's more efficient to build that subtree once instead of rebuilding it on every ReactterContext changes.

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,
      ],
    );
  },
)
