when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String? id,
    3. String value,
    4. List<MutedWordTarget> targets,
    5. MutedWordActorTarget? actorTarget,
    6. DateTime? expiresAt,
    7. Map<String, dynamic>? $unknown,
    )
)

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 $type,  String? id,  String value, @MutedWordTargetConverter()  List<MutedWordTarget> targets, @MutedWordActorTargetConverter()  MutedWordActorTarget? actorTarget,  DateTime? expiresAt,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _MutedWord():
return $default(_that.$type,_that.id,_that.value,_that.targets,_that.actorTarget,_that.expiresAt,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
