when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? version,
    2. String? method,
    3. XrayStringList? path,
    4. Map<String, XrayStringList>? headers,
    )
)

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? version,  String? method,  XrayStringList? path,  Map<String, XrayStringList>? headers)  $default,) {final _that = this;
switch (_that) {
case _AuthenticatorRequest():
return $default(_that.version,_that.method,_that.path,_that.headers);case _:
  throw StateError('Unexpected subclass');

}
}
