ON MAIN INIT STATE

@override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addPostFrameCallback((timeStamp) {
      _deepLinkConfiguration = DeepLinkConfiguration();
      _deepLinkConfiguration.initDeepLinkListener(context);
    });
  }

But remember you can only test deep link if you build your app with release mode, and if you publish it on playstore add playstore SHA-1
