ReactterProvider<T extends ReactterContext> class

A wrapper StatelessWidget that provides a ReactterContext's instance of T to widget tree that can be access through the BuildContext.

ReactterProvider(
  () => AppContext(),
  builder: (context, child) {
    final appContext = context.watch<AppContext>();
    return Text("state: ${appContext.stateHook.value}");
  },
)

IMPORTANT: Don's use ReactterContext with constructor parameters to prevent conflicts. Instead of it, use onInit method to access its instance and put the data you need.

NOTE: ReactteProvider is a "scoped". So it contains a ReactterScope which 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.

If you want to create a different ReactterContext's instance, use id parameter.

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.

ReactterProvider(
  () => AppContext(),
  child: Text("This widget build only once"),
  builder: (context, child) {
    final appContext = context.watch<AppContext>();
    return Column(
      children: [
        Text("state: ${appContext.stateHook.value}"),
        child,
      ],
    );
  },
)
