when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. bool noOverride,
    2. List<ModerationCause> filters,
    3. List<ModerationCause> blurs,
    4. List<ModerationCause> alerts,
    5. List<ModerationCause> informs,
    )
)

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( bool noOverride,  List<ModerationCause> filters,  List<ModerationCause> blurs,  List<ModerationCause> alerts,  List<ModerationCause> informs)  $default,) {final _that = this;
switch (_that) {
case _ModerationUI():
return $default(_that.noOverride,_that.filters,_that.blurs,_that.alerts,_that.informs);case _:
  throw StateError('Unexpected subclass');

}
}
