when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? type,
    2. String? packet,
    3. XrayInt32Range? delay,
    4. String? applyTo,
    )
)

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 ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String? type,  String? packet,  XrayInt32Range? delay,  String? applyTo)  $default,) {final _that = this;
switch (_that) {
case _Noise():
return $default(_that.type,_that.packet,_that.delay,_that.applyTo);case _:
  throw StateError('Unexpected subclass');

}
}
