whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(@JsonKey.new(name: 'method') String? cipher, String? password, int? level, String? email, @JsonKey.new(name: 'clients') List<ShadowsocksUserConfig>? users, @JsonKey.new(name: 'network') XrayNetworkList? networkList,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function(@JsonKey(name: 'method')  String? cipher,  String? password,  int? level,  String? email, @JsonKey(name: 'clients')  List<ShadowsocksUserConfig>? users, @JsonKey(name: 'network')  XrayNetworkList? networkList)?  $default,) {final _that = this;
switch (_that) {
case _ShadowsocksServerConfig() when $default != null:
return $default(_that.cipher,_that.password,_that.level,_that.email,_that.users,_that.networkList);case _:
  return null;

}
}
