whenOrNull<TResult extends Object?> method
- @optionalTypeArgs
- TResult? $default(
- XrayAddress? address,
- int? port,
- Map<
String, String> ? portMap, - @JsonKey.new(name: 'network') XrayNetworkList? network,
- bool? followRedirect,
- int? userLevel,
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( XrayAddress? address, int? port, Map<String, String>? portMap, @JsonKey(name: 'network') XrayNetworkList? network, bool? followRedirect, int? userLevel)? $default,) {final _that = this;
switch (_that) {
case _DokodemoConfig() when $default != null:
return $default(_that.address,_that.port,_that.portMap,_that.network,_that.followRedirect,_that.userLevel);case _:
return null;
}
