I debugged my demo
, It is found that the FlutterTouchInterceptingView DelayingGestureRecognizer interception is an event

I added the following code and it works as expected：

override func hitTest(_ point: CGPoint, with event: UIEvent?) -> UIView? {
        
        let view = super.hitTest(point, with: event);
        
        let gestureRecognizers = self.superview?.superview?.gestureRecognizers ?? []
        for gesture in gestureRecognizers{
        
            gesture.isEnabled = false
        }
        return view
    }```

I have the same issue and that code snippet solved it. However, I'm not sure if it impacts something else.

Thanks @swordyy7 for the fix!

To anyone else who wants to try this fix, I just published a fork of flutter_inappwebview with the touch delay fix provided by @swordyy7.

  • flutter pub remove flutter_inappwebview
  • flutter pub add flutter_inappwebview_fix_iostouchdelay
  • Update your imports from flutter_inappwebview to flutter_inappwebview_fix_iostouchdelay, example:
    • From: import "package:flutter_inappwebview/flutter_inappwebview.dart";
    • To: import "package:flutter_inappwebview_fix_iostouchdelay/flutter_inappwebview_fix_iostouchdelay.dart";

The forked library is listed on pub.dev here, and the source code is here.

Hope this helps someone. :)

The code snippet resolve the touch issue but it disables the interaction with any flutter native components displayed on top of the WebView! :(
