enable scrolling with Trackpad #274

I can scroll with the mouse wheel, but I cannot with the trackpad.

This is because scroll events from the trackpad are sent via onPointerPanZoomUpdate, not onPointerSignal. https://docs.flutter.dev/release/breaking-changes/trackpad-gestures

By sending the amount of scroll, panDelta in PointerPanZoomUpdateEvent, to the webview, I can scroll with the trackpad.
