Intent-filters getting mixed up

[alexboulay]

So my app supports Android AppLinks, so a user can open https://example.com/some-route and get inside the app.

Here is the intent-filter inside my main activity:

<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="www.example.com" />
</intent-filter>

As you may observe, the host is specified and no path, pathPattern or pathPrefix are specific so any links can open this.

On the other hand, the intent-filter related to flutter_web_auth_2 does have specificity using a pathPrefix:

<activity
android:name="com.linusu.flutter_web_auth_2.CallbackActivity"
android:exported="true">
    meta-data android:name="flutter_deeplinking_enabled" android:value="true" />
    <intent-filter android:label="flutter_web_auth_2" 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="www.example.com" android:pathPrefix="/oauth-callback"  />
    </intent-filter>
</activity> 

I am wrong with this approach? It seems like even the specific url still opens my default activity and the callback activity gets ignored. The only way to get it working is removing the intent-filter inside my app or make that one specific.

Any guidance or clarification is appreciated on how I can achieve this! Thanks!

Good question... You will probably be better off asking on StackOverflow, actually.
Intent filters with https as scheme have always been troublesome and many issues were opened here already about this.
All I can say is that flutter_web_auth_2 is not at fault - but still, it is not very clear on how to make them work properly.
