maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult repoRef(
    1. RepoRef data
    )?,
  2. TResult repoStrongRef(
    1. RepoStrongRef data
    )?,
  3. TResult unknown(
    1. Map<String, dynamic> data
    )?,
  4. 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( RepoRef data)?  repoRef,TResult Function( RepoStrongRef data)?  repoStrongRef,TResult Function( Map<String, dynamic> data)?  unknown,required TResult orElse(),}) {final _that = this;
switch (_that) {
case UModerationCreateReportSubjectRepoRef() when repoRef != null:
return repoRef(_that.data);case UModerationCreateReportSubjectRepoStrongRef() when repoStrongRef != null:
return repoStrongRef(_that.data);case UModerationCreateReportSubjectUnknown() when unknown != null:
return unknown(_that.data);case _:
  return orElse();

}
