whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. XrayTargetStrategy? targetStrategy,
    2. XrayTargetStrategy? domainStrategy,
    3. String? redirect,
    4. int? userLevel,
    5. Fragment? fragment,
    6. Noise? noise,
    7. List<Noise>? noises,
    8. int? proxyProtocol,
    9. XrayStringList? ipsBlocked,
    )?
)

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( XrayTargetStrategy? targetStrategy,  XrayTargetStrategy? domainStrategy,  String? redirect,  int? userLevel,  Fragment? fragment,  Noise? noise,  List<Noise>? noises,  int? proxyProtocol,  XrayStringList? ipsBlocked)?  $default,) {final _that = this;
switch (_that) {
case _FreedomConfig() when $default != null:
return $default(_that.targetStrategy,_that.domainStrategy,_that.redirect,_that.userLevel,_that.fragment,_that.noise,_that.noises,_that.proxyProtocol,_that.ipsBlocked);case _:
  return null;

}
