UseContext<T extends ReactterContext> class

A ReactterHook that helps to get the context of ReactterContext by T with or without id.

final appContextHook = UseContext<AppContext>();
final appContextWithIdHook = UseContext<AppContext>('uniqueId');

The context that you need to get, to must be created by ReactterInstanceManager:

Reactter.create<AppContext>(() => AppContex());

or created by ReactterProvider of flutter_reactter

You can get instance, using instance getter:

final appContextHook = UseContext<AppContext>();
print(appContextHook.instance);

instance returns null, when the instance is not found or it hasn't created yet.

To wait for the instance to be created, you need to use the UseEffect hook.

final appContextHook = UseContext<AppContext>(null, this);
print(appContextHook.instance); // return null

UseEffect(() {
  print(appContextHook.instance); // return instance of AppContext
}, [appContextHook]);

You should call dispose when it's no longer needed.
