when<TResult extends Object?> method

@optionalTypeArgs TResult when<TResult extends Object?>({ required TResult basic(String username, String password), required TResult bearer(String token), required TResult header(String username, String password), })

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?>({required TResult Function( String username,  String password)  basic,required TResult Function( String token)  bearer,required TResult Function( String name,  String value)  header,}) {final _that = this;
switch (_that) {
case AuthConfig_Basic():
return basic(_that.username,_that.password);case AuthConfig_Bearer():
return bearer(_that.token);case AuthConfig_Header():
return header(_that.name,_that.value);}
}
