deep linking - Flutter Application Won't Verify App Link On Android

Question

I'm trying to have my application use app links, but even though I went through all the steps and my assetlinks.json file is being requested, the disambiguation box still shows up. I tried the same steps with a native android app, and it worked without showing the box. Here is what I did:

1- Create a new flutter application. 2- Signed my application following the instructions on https://flutter.dev/docs/deployment/android 3- Add the following to my activity in AndroidManifest.xml

<intent-filter android:autoVerify="true">
                <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"
                    android:host="<example.come>" />
            </intent-filter>

I replaced example.com with my own domain, have https enabled, and serving /.well-known/assetlinks.json

Here is the content of assetlinks.json

[
    {
        "relation": [
            "delegate_permission/common.handle_all_urls"
        ],
        "target": {
            "namespace": "android_app",
            "package_name": "com.example.app",
            "sha256_cert_fingerprints": [
                "hash_of_app_certificate"
            ]
        }
    }
]

I replaced com.example.app with my own, and changed the hash. I used this command to obtain the hash keytool -list -v -keystore <keystore path> -alias <key alias> -storepass <store password> -keypass <key password>

4- Ran flutter build apk and installed the app on my device. I can tell that assetlinks.json has been requested from the server, but the selection box still shows up.

I tested my assertlinks.json on https://developers.google.com/digital-asset-links/tools/generator and it says it is successful so whatever is wrong is on the app side.

What am I missing or doing wrong?
