when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. Map<String, String> scopes,
    2. String? authorizationUrl,
    3. String? tokenUrl,
    4. String? refreshUrl,
    )
)

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( Map<String, String> scopes,  String? authorizationUrl,  String? tokenUrl,  String? refreshUrl)  $default,) {final _that = this;
switch (_that) {
case _OAuthFlow():
return $default(_that.scopes,_that.authorizationUrl,_that.tokenUrl,_that.refreshUrl);case _:
  throw StateError('Unexpected subclass');

}
}
