AsyncSnapshot<T>.withError constructor Null safety

const AsyncSnapshot<T>.withError(
  1. ConnectionState state,
  2. Object error,
  3. [StackTrace stackTrace = StackTrace.empty]
)

Creates an AsyncSnapshot in the specified state with the specified error and a stackTrace.

If no stackTrace is explicitly specified, StackTrace.empty will be used instead.

Implementation

const AsyncSnapshot.withError(
  ConnectionState state,
  Object error, [
  StackTrace stackTrace = StackTrace.empty,
]) : this._(state, null, error, stackTrace);
