Use case

I discovered that Android task hijacking is allowed in a flutter application, any malicious app can put itself on the stack of the flutter application by adding taskAffinity="com.example.myFlutterApp" in the AndroidManifest.xml of the <activity> tag of the MainActivity

Steps to Reproduce

2. create a new blank android project, in AndroidManifest.xml add
   android:excludeFromRecents="true" android:launchMode="singleTask" android:taskAffinity="{com.example.myFlutterApp}" in the <activity> tag from the MainActivity.
3. open the com.example.myflutterapp application.
4. run the android app
5. close it and open the flutter application again

Expected results:

The flutter application

Actual results:

the android application

Proposal

Automatically add android:taskAffinity="" to the <application> tag in the AndroidManifest.xml of the flutter app
