"W/MotionEvent-JNI(11414): android_view_MotionEvent_nativeGetPointerCount: -1" warnings keep filling the terminal

### Steps to reproduce

When I use a normal `GestureDetector` I get my terminal filled with warnings on the motion event, such as this:

```
W/MotionEvent-JNI(11414): android_view_MotionEvent_nativeGetPointerCount: -1
```


### Expected results

I expect the touch events of the `GestureDetector` to not trigger any warning

### Actual results

I get spammed with the following warning whenever I touch the `GestureDetector`:
```
W/MotionEvent-JNI(11414): android_view_MotionEvent_nativeGetPointerCount: -1
```

### Code sample

<details open><summary>Code sample</summary>

The code needed to reproduce this error is a simple `StatefulWidget` with a single `GestureDetector` button:
```dart
class TestGraphics extends StatefulWidget {
  const TestGraphics({super.key});

  @override
  State<TestGraphics> createState() => _TestGraphicsState();
}

class _TestGraphicsState extends State<TestGraphics> {
  @override
  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          GestureDetector(
            onTap: () {
              print("TEST");
            },
            child: Container(color: Colors.amber, width: 100, height: 100),
          ),
         ],
      ),
    );
  }
}
```
