Flutter Firebase Dynamic Links ActivityNotFoundException

Question

I'm having some issue with Firebase Dynamic Links in combination with my Flutter app. I run into the issue below when running the the Flutter app. This only happens on Android 13 all version below work fine.

Activity not found to handle Intent action [CONTEXT service_id=77 ]
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.foo.bar/com.foo.bar.MainActivity}; have you declared this activity in your AndroidManifest.xml, or does your intent not match its declared <intent-filter>?

Now Android is since version 13 handling the intents more strictly. So I think I might have a small configuration mistake somewhere only I just cannot find it. Already had contact with Firebase Support but they tell me that this issue is out of scope.

I was hoping maybe someone here knows what is configured incorrectly.

The link I'm using is:

https://foobar.page.link/?link=https://foo-bar-a5111.firebaseapp.com/__/auth/action?apiKey%3DAIzaSyDHlkdWSvP0RLERv3dYszCB6rJG66CL49c%26mode%3DsignIn%26oobCode%3Di9r0XZY8GjHNlvZbEeoAwhGkPCpwsT_m43AIt-gFnDIAAAGGgGtBOQ%26continueUrl%3Dhttps://foo.bar/registration_email_verification?id%253D123%26lang%3Den&apn=com.foo.bar&amv&afl=https://foo-bar-a5111.firebaseapp.com/__/auth/action?apiKey%3DYIzaSyDXlkdWSvP8RLERv3dYszCB6rJ666CL49c%26mode%3DsignIn%26oobCode%3Di9r0XZY8GjHNlvZbEeoAwhGkPCpwsT_m43AIt-gFnDIAAAGGgGtBOQ%26continueUrl%3Dhttps://foo.bar/registration_email_verification?id%253D123%26lang%3Den

Firebase is opening the app with the https://foo-bar-a5111.firebaseapp.com/__/auth/action... URL as configured in the link query parameter. This meant that I needed to update my <intent-filter> allow the host from that link to this:

            <intent-filter>
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="https" />
                <data android:host="foo.bar" />
                <data android:host="foo-bar-a5111.firebaseapp.com" />
            </intent-filter>

I hope this saves you guys some time!
