Description
Steps to reproduce
When I set focus mode from locked to auto on android it crashes with null pointer exception.
Setting the mode from auto to locked is OK.
On iOS is fine. I'm testing with Pixel 6(Android 15).
camera: ^0.11.1
Expected results
Expecting not to crash :)
Actual results

Code sample
Code sample
void _initCamera() {
cameraController!.initialize().then((_) {
Log.d("camera init", tag);
cameraController!.setFocusMode(FocusMode.locked);
add(ControllerInitialized(cameraController));
}, onError: (error) async {
Log.error("camera init", error: error);
});
}
///When this function is called with FocusMode.locked is ok, for FocusMode.auto it crashes on android
Future<bool> setFocusMode(FocusMode mode) async{
try {
await cameraController!.setFocusMode(mode);
add(OnFocusMode(mode));
return true;
} catch (e) {
Log.error("setFocusMode $mode", error: e, tag: tag);
return false;
}
