findAllMobileDragHandles static method

Finder findAllMobileDragHandles([ Finder? superReaderFinder ])

Returns true if any type of mobile drag handles are visible, or false if not.

On iOS, drag handles include the caret, as well as the upstream and downstream handles.

On Android, drag handles include the caret handle, as well as the upstream and downstream drag handles. The caret drag handle on Android disappears after a brief period of inactivity, and reappears upon another user interaction.

            widget.key == DocumentKeys.upstreamHandle ||
            widget.key == DocumentKeys.downstreamHandle,
      );
