maybeMap<TResult extends Object?> method

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({ TResult notInitialized(_NotInitializedDevicePreviewState value)?, TResult initializing(_InitializingDevicePreviewState value)?, TResult initialized(_InitializedDevicePreviewState value)?, required TResult orElse(), })

A variant of map that fallback to returning orElse.

It is equivalent to doing:

switch (sealedClass) {
  case final Subclass value:
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  TResult Function(_NotInitializedDevicePreviewState value)? notInitialized,
  TResult Function(_InitializingDevicePreviewState value)? initializing,
  TResult Function(_InitializedDevicePreviewState value)? initialized,
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _NotInitializedDevicePreviewState() when notInitialized != null:
      return notInitialized(_that);
    case _InitializingDevicePreviewState() when initializing != null:
      return initializing(_that);
    case _InitializedDevicePreviewState() when initialized != null:
      return initialized(_that);
    case _:
      return orElse();
  }
}
