maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. List<ThreadItem> thread,
    2. ThreadgateView? threadgate,
    3. bool hasOtherReplies,
    4. Map<String, dynamic>? $unknown,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function(@ThreadItemConverter()  List<ThreadItem> thread, @ThreadgateViewConverter()  ThreadgateView? threadgate,  bool hasOtherReplies,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _UnspeccedGetPostThreadV2Output() when $default != null:
return $default(_that.thread,_that.threadgate,_that.hasOtherReplies,_that.$unknown);case _:
  return orElse();

}
}
