AsyncSlot<T> class
A widget that rebuilds when an AsyncSignal changes.
Handles the different states of an AsyncState: data, error, and loading.
Basic Usage
final user = AsyncSignal<User>(() => fetchUser());
AsyncSlot(
connect: user,
onData: (context, data) => UserProfile(user: data),
onLoading: (context) => const CircularProgressIndicator(),
onError: (context, error) => Text('Error: $error'),
)
