maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(XrayAddress address, int port, int? level, String? email, @JsonKey.new(name: 'method') String? cipher, String password, bool? uot, int? uotVersion,)?, { 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(
          XrayAddress address,
          int port,
          int? level,
          String? email,
          @JsonKey(name: 'method') String? cipher,
          String password,
          bool? uot,
          int? uotVersion)?
      $default, {
  required TResult orElse(),
}) {
  final _that = this;
  switch (_that) {
    case _ShadowsocksServerTarget() when $default != null:
      return $default(_that.address, _that.port, _that.level, _that.email,
          _that.cipher, _that.password, _that.uot, _that.uotVersion);
    case _:
      return orElse();
