fold method

  1. @override
Resolvable<Object> fold(
  1. @noFuturesAllowed Resolvable<Object>? onSync(
    1. Sync<T> sync
    ),
  2. @noFuturesAllowed Resolvable<Object>? onAsync(
    1. Async<T> async
    )
)
override

Handles Sync and Async cases to produce a new Resolvable.

Implementation

@override
Resolvable<Object> fold(
  @noFuturesAllowed Resolvable<Object>? Function(Sync<T> sync) onSync,
  @noFuturesAllowed Resolvable<Object>? Function(Async<T> async) onAsync,
) {
  try {
    return onSync(this) ?? this;
  } catch (error) {
    return Sync.unsafe(Err(error));
  }
}
