Steps to Reproduce

I used AndroidView to call the native map component, which happens when I use a three-finger drag.

I make screenshot in Xiaomi device (while google map module is opened). (swipe down with 3 fingers). These gestures always throw such exception.
Before exception there is such message in logs:
D/ViewRootImpl(22189): cancle motionEvent because of threeGesture detecting

Is there a better way to solve the problem so far.

Same issue as above LOG with latest version of flutter stable channel and latest version of google_maps_flutter package.

Take a look at #20517 solved the problem with a workaround, modify the file packages/flutter/lib/src/rendering/platform_view.dart

Hi all
if the issue persist with the latest stable version of flutter
could you please provide your flutter doctor -v ,
your flutter run --verbose
and a reproducible minimal code sample.

Given these prs
flutter/engine#13697,
#44217,
could be useful to check if reproduces on the latest master as well

Thank you

I solved this problem by a sinple modification in packages/flutter/lib/src/rendering/platform_view.dart:

bool isSinglePointerAction(PointerEvent event) =>
//change from 
      !(event is PointerDownEvent) && !(event is PointerUpEvent); 
//to
      !(event is PointerDownEvent) && !(event is PointerUpEvent) && !(event is PointerCancelEvent);
