LStatusBuilder<T> class

A widget specialized for handling LxStatus.

Eliminates boilerplate when handling loading, error, and success states of an asynchronous reactive value.

// Example usage:

LStatusBuilder(
  userStatus,
  onSuccess: (user) => UserProfile(user),
  onWaiting: () => const LoadingSpinner(),
  onError: (e, s) => ErrorView(e),
);
Inheritance

Constructors

LStatusBuilder(LxReactive<LxStatus<T>> x, {Key? key, required Widget onSuccess(T data), Widget onWaiting()?, Widget onError(Object error, StackTrace? stackTrace)?, Widget onIdle()?})
Creates a status-aware builder.
