Flutter how to get firebase dynamic link if app is already running?

Question

I receive a firebase dynamic link in initState.

This works great if the app is completely off. But if the app was running before clicking the link, initState is not called again, thus the dynamiclink is not processed.

Should I try to process the firebase dynamic link through WidgetsBindingObserver (for a similar effect to onResume in Android)? If not, what would be the proper way?

I had the same problem and I solved using WidgetsBindingObserver to listen when the app is foreground, but I found an issue on iOS.

I wrote a post about it, you can check it:

Is it safe to just change the pubspec file to the git? Is there any cleanup necessary before I do the switch or will that all be automatic? – Gabeloooooo Aug 21 '18 at 21:03
it should be temporal until they accept the pull request, flutter clean / flutter packages get – diegoveloper Aug 21 '18 at 21:05

Just like .getInitialLink() there is an onLink() listener now.

FirebaseDynamicLinks.instance.onLink(
    onSuccess: (PendingDynamicLinkData dynamicLink) async {
      final Uri deepLink = dynamicLink?.link;

      if (deepLink != null) {
        // Process your deeplink
      }
    },
    onError: (OnLinkErrorException e) async {}
);
