when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String contentText,
    2. String okText,
    3. String cancelText,
    4. @igFreezedJson Widget? content,
    5. @igFreezedJson Widget? title,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<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():
return $default(_that.contentText,_that.okText,_that.cancelText,_that.content,_that.title);}
}
