Cannot scroll up/down with remote-control like AnyDesk. Taps/mouse clicks work ok. Scroll up/down outside EL is ok. about elder_launcher HOT 1 OPEN

Hi. Thanks for the detailed report. I investigated and reproduced this behavior in the official Flutter Gallery app too. The app is made in Flutter which uses Skia renderer to draw the interface. This might be an upstream issue. I'll do a few experiments to see why gestures from Anydesk aren't working with Flutter.

Test 1: Created a basic app with scrollable list of 125 numbers in Flutter.

Scaffold(
  body: ListView.builder(
     itemCount: 125,
     itemBuilder: (_, index) => Text(index.toString(),
   ),
);

Scrolling in AnyDesk does not work. Scrolling by touch on the phone works of course.
Scrolling via AnyDesk doesn't trigger ScrollListeners from the Flutter ScrollController. It is used in all sorts of lists & grids.

Test 2: Wrapped Notification Listeners around the list of numbers.
Scroll Notification are received when scrolling by touch on the phone.
Scroll Notifications are not received when trying to scroll using AnyDesk.

Test 3: Gesture Detector detects drag gestures from AnyDesk
The GestureDetector does detect drag movements. All classes inheriting from ScrollView class are affected: ListView, GridView and CustomScrollView. Additionally a SingleChildScrollView doesn't fix this either.
