Compose Modifier
motionEventSpy
Android
```kotlin
fun Modifier.motionEventSpy(watcher: (motionEvent: MotionEvent) -> Unit): Modifier
```
Calls `watcher` with each `MotionEvent` that the layout area or any child `pointerInput`
receives. The `MotionEvent` may or may not have been transformed to the local coordinate system.
The Compose View will be considered as handling the `MotionEvent` in the area that the
`motionEventSpy` is active.
This method can only be used to observe `MotionEvent`s and can not be used to capture an event
stream.
`watcher` is called during the `PointerEventPass.Initial` pass.
Developers should use `pointerInput` to handle pointer input processing within Compose.
`motionEventSpy` is only useful as part of Android View interoperability.
If you need to handle and consume `MotionEvent`s, use `pointerInteropFilter`.
