when<TResult extends Object?> method
- @optionalTypeArgs
- TResult $default(
- List<
HTTPAccount> ? accounts, - @JsonKey.new(name: 'allowTransparent') bool? transparent,
- int? userLevel
- List<
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( List<HTTPAccount>? accounts, @JsonKey(name: 'allowTransparent') bool? transparent, int? userLevel) $default,) {final _that = this;
switch (_that) {
case _HTTPServerConfig():
return $default(_that.accounts,_that.transparent,_that.userLevel);case _:
throw StateError('Unexpected subclass');
}
}
