                InAppWebView(initialUrlRequest: URLRequest(url: Uri.parse("https://flutter.dev/"))),
                Icon(Icons.directions_transit, size: 350),
                Icon(Icons.directions_car, size: 350),
                Icon(Icons.directions_bike, size: 350),
                Icon(Icons.directions_boat, size: 350),
              ],
            ),
          )),
        ),
      ),
    );
  }
}

Solution

Try adding a gesture detector, like this:

InAppWebView(
gestureRecognizers: Set()..add(Factory<VerticalDragGestureRecognizer>(() => VerticalDragGestureRecognizer())),
initialUrlRequest: URLRequest(url: Uri.parse("https://flutter.dev/"))),
               

If this doesn’t solve your problem, this is the place you have to look, gesture detectors.
