when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String protocol,
    2. String? sendThrough,
    3. String? tag,
    4. XrayOutboundSettings? settings,
    5. StreamConfig? streamSettings,
    6. ProxyConfig? proxySettings,
    7. MuxConfig? mux,
    8. XrayTargetStrategy? targetStrategy,
    )
)

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 ...;
}
