You can use firebase dynamic links for that. Refer this link https://medium.com/better-programming/deep-linking-in-flutter-with-firebase-dynamic-links-8a4b1981e1eb
Retrieve dynamic link in flutter like this and open form screen when link get in register listener.
class MainWidgetState extends State<MainWidget> {
#override
void initState() {
super.initState();
this.initDynamicLinks();
}
initDynamicLinks(BuildContext context) async {
await Future.delayed(Duration(seconds: 3));
var data = await FirebaseDynamicLinks.instance.getInitialLink();
var deepLink = data?.link;
final queryParams = deepLink.queryParameters;
if (queryParams.length > 0) {
var userName = queryParams['userId'];
openFormScreen(userName);
}
FirebaseDynamicLinks.instance.onLink(onSuccess: (dynamicLink)
async {
var deepLink = dynamicLink?.link;
final queryParams = deepLink.queryParameters;
if (queryParams.length > 0) {
var userName = queryParams['userId'];
openFormScreen(userName);
}
debugPrint('DynamicLinks onLink $deepLink');
}, onError: (e) async {
debugPrint('DynamicLinks onError $e');
});
}
openFormScreen(String userName){
Navigator.of(context).pushNamed("routeFormScreen", arguments: {"name": userName});
}
}
