futurePod<T> function

FuturePod<T> futurePod<T>(ReaderPod<Future<T>> create)

Create a PodFuture that returns a AsyncValue representing the current state of the Future's execution.

The future property is set to the Future itself, so you can await it if required.

Implementation

FuturePod<T> futurePod<T>(
  ReaderPod<Future<T>> create,
) =>
    PodFuture(
      pod(create),
      (ref, pod) {
        var disposed = false;
        ref.onDispose(() => disposed = true);

        ref.watch(pod).then(
          (value) {
            if (disposed) return;
            ref.setSelf(AsyncValue<T>.data(value));
          },
          onError: (Object error, StackTrace stackTrace) {
            if (disposed) return;
            ref.setSelf(AsyncValue<T>.error(error, stackTrace));
          },
        );

        final previous = ref.self();
        final loading = AsyncValue<T>.loading();

        if (previous == null) {
          return loading;
        }

        return loading.copyWithPrevious(ref.self()!);
      },
    );
