whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String contentText, String okText, String cancelText, @igFreezedJson Widget? content, @igFreezedJson Widget? title,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

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

}
}
