when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. bool? noKernelTun,
    2. String secretKey,
    3. List<String>? address,
    4. List<String>? remoteDNS,
    5. List<WireGuardPeerConfig>? peers,
    6. @JsonKey.new(name: 'mtu') int? mtu,
    7. List<int>? reserved,
    8. XrayTargetStrategy? domainStrategy,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}
