Description
I have a handful of buttons on top of my Mapbox map that perform various functions with the map. One of them is a "3D view toggle". This function just calls easeTo. Im getting some strange behaviour after interacting with this button that I dont get at all if I dont touch it. Ive attached the code were using as well as a video of what this issue looks like.
Mapbox SDK Version: Seems to be all
Testing on iOS
```
void _togglePitch() {
// Prevent multiple simultaneous pitch changes
if (_isEasingInProgress) {
return;
}
// Ensures mapboxMap is not null before attempting to use it
if (mapboxMap == null) {
debugPrint('MapboxMap is not initialized');
return;
}
try {
// Set flag to prevent additional calls
setState(() {
_isEasingInProgress = true;
is3D = !is3D;
});
mapboxMap!.easeTo(
CameraOptions(pitch: is3D ? 75 : 0),
MapAnimationOptions(duration: 1000),
).then((_) {
// Reset the flag when animation is complete
setState(() {
_isEasingInProgress = false;
});
}).catchError((error) {
debugPrint('Error toggling pitch: $error');
setState(() {
is3D = !is3D;
_isEasingInProgress = false;
});
});
} catch (e) {
debugPrint('Error toggling pitch: $e');
// Optionally, reverts the state if the pitch change fails
setState(() {
is3D = !is3D;
_isEasingInProgress = false;
});
}
}
```

Contributor guide
Research direction
Start with the supplied _togglePitch function and its easeTo call, then reproduce the reported behavior on iOS using the attached code and video. Compare behavior with and without the 3D toggle across the stated SDK versions; done when the memory behavior is explained and a minimal reproduction or confirmed cause is documented.
