maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String contentText, String okText, String cancelText, Widget? content, Widget? title,)?, { required TResult orElse(), })

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  TResult Function(String contentText, String okText, String cancelText,
          @igFreezedJson Widget? content, @igFreezedJson Widget? title)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _AskOkDialogParams() when $default != null:
      return $default(_that.contentText, _that.okText, _that.cancelText,
          _that.content, _that.title);
    case _:
      return orElse();
  }
}
