initial method

@override AsyncSnapshot<T> initial()

Returns the initial summary of stream interaction, typically representing the fact that no interaction has happened at all.

Sub-classes must override this method to provide the initial value for the fold computation.

Implementation

@override
AsyncSnapshot<T> initial() {
  if (initialError != null) return AsyncSnapshot<T>.withError(ConnectionState.none, initialError!);
  return initialData == null
    ? AsyncSnapshot<T>.nothing()
    : AsyncSnapshot<T>.withData(ConnectionState.none, initialData as T);
}
