whenOrNull<R> method

R? whenOrNull<R>(
  1. {R data(
    1. T data
    )?,
  2. R error(
    1. Object error,
    2. StackTrace? stackTrace
    )?,
  3. R loading(
      )?}
    )

    Perform actions conditionally based on the state of the AsyncValue.

    Returns null if AsyncValue was in a state that was not handled.

    This is similar to maybeWhen where orElse returns null.

    Implementation

    R? whenOrNull<R>({
  R Function(T data)? data,
  R Function(Object error, StackTrace? stackTrace)? error,
  R Function()? loading,
}) {
  return _map(
    data: (d) => data?.call(d.value),
    error: (e) => error?.call(e.error, e.stackTrace),
    loading: (l) => loading?.call(),
  );
}
