FirebaseDynamicLinks.instance.getInitialLink() only works after using a Timer to delay the call

[stephenhuey]

I'm using

firebase_dynamic_links: 0.5.0+11

and the current version of the FirebaseDynamicLinks.instance.getInitialLink() method does not find the initial link unless I wait 700+ milliseconds to try retrieving it.

I'm referring to the sample code at these 2 links:

https://pub.dev/packages/firebase_dynamic_links

https://github.com/FirebaseExtended/flutterfire/blob/master/packages/firebase_dynamic_links/example/lib/main.dart

Here is what it looks like when I simply add a Timer to the sample code:

  @override
  void initState() {
    super.initState();
    _timerLink = new Timer(const Duration(milliseconds: 700), () {
      print('700 ms later, going to init dynamic links');
      this.initDynamicLinks();
    });
  }

This successfully finds the link, but if I do not use the Timer it does not find the link. To be clear, this is when I do a fresh install of the app on the iPhone after tapping a dynamic link (and it gets automatically copied to the clipboard). For the record, onLink works when I try to open a link while the Flutter app is already running in the background on my iPhone.
