when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>(TResult $default(String placeholder, String title, String okBtnText, String cancelBtnText, @igFreezedJson bool disableOkButton(int value)?, @igFreezedJson String? errorMessage(int value)?, @igFreezedJson TextStyle? okButtonTextStyle, @igFreezedJson TextStyle? cancelButtonTextStyle,))

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 placeholder,  String title,  String okBtnText,  String cancelBtnText, @igFreezedJson  bool Function(int value)? disableOkButton, @igFreezedJson  String? Function(int value)? errorMessage, @igFreezedJson  TextStyle? okButtonTextStyle, @igFreezedJson  TextStyle? cancelButtonTextStyle)  $default,) {final _that = this;
switch (_that) {
case _AskIntDialogParams():
return $default(_that.placeholder,_that.title,_that.okBtnText,_that.cancelBtnText,_that.disableOkButton,_that.errorMessage,_that.okButtonTextStyle,_that.cancelButtonTextStyle);}
}
