Operating System: Ubuntu 20.04.6 LTS
Flutter 3.24

When I render HTML on a Linux platform on a touch device, no scroll event is triggered when I swipe the window content with a scroll bar with one finger.
Currently, the default effect when you swipe your finger is to select the text, which is not what I want.

Kindly I want to know how to deal the touch event？ Which class should I focus? How should I set it up?
