Reactive class

A widget that rebuilds itself when notified via refresh or refreshOnly.

This is the core reactive widget of the library. It subscribes itself to a ReactiveKey and rebuilds when Reactivity.notifier triggers updates associated with that key.

Example

Reactive(() => Text('Count: $count'));

If you want to refresh only a specific instance:

final myKey = ReactiveKey();

Reactive(
  () => Text('Hello'),
  reactiveKey: myKey,
);

refreshOnly(myKey);
