startParam property

String? get startParam

Optional. The value of the startattach parameter, passed via link. Only returned for Mini Apps when launched from the attachment menu via link.

Implementation

//
// The value of the start_param parameter will also be passed in the
// GET-parameter tgWebAppStartParam, so the Mini App can load the correct
// interface right away.
String? get startParam => _jsInitData.start_param;
