[Touch] Scrolling does not work

[cm-t]

Hi,

On a Ubuntu (gnome-shell) 24.04 LTS installation (Tablet StarLite from starlabs). App-center up to date.

Expected:

• I open an apps
• I need to scroll
• I use touchscreen to scroll
• works

Result on app-center:

• I open app-center
• I browser categories, or search result; I need to scroll
• I use touch screen (1 finger like I do in gnome apps or firefox)
• does not work
  • Then I try 2 finger scroll
    • still not works

Current user workaround:

• put finger on the right side of the screen
• scroll bar appears
• drag and drop it
  • with small touch area of it, and its infinite scroll (search result) it is not a good UX

I think we need to add this to MaterialAPp

scrollBehavior: const MaterialScrollBehavior().copyWith( dragDevices: { PointerDeviceKind.mouse, PointerDeviceKind.touch, PointerDeviceKind.stylus, PointerDeviceKind.unknown, PointerDeviceKind.trackpad, }, ),

I think we already have an issue for this somewhere
