maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({ TResult oauth(String accessToken, String idToken)?, 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( String accessToken,  String idToken)?  oauth,required TResult orElse(),}) {final _that = this;
switch (_that) {
case OAuthCredentials() when oauth != null:
return oauth(_that.accessToken,_that.idToken);case _:
  return orElse();

}
}
