FlutterError - type 'Null' is not a subtype of type 'Controller' in type cast

[andiigtayma]

Describe the bug
Seems to be frequently thrown 3-4 times over the last week. There are other bottom sheets being used in the fashion but the error has not come up over those.

Fatal Exception: io.flutter.plugins.firebase.crashlytics.FlutterError: type 'Null' is not a subtype of type 'OrderDetailsController' in type cast. Error thrown .

Reproduction code

/// in OrderDetailsController
 await Get.bottomSheet(
      CODMethodSelectionBottomSheet(),
      isDismissible: false,
    );


class CODMethodSelectionBottomSheet extends GetWidget<OrderDetailsController> {
}

To Reproduce
I could not find a way to reliably reproduce this issue.

Expected behavior
The Exception should never come up because the controller is always available when calling the code.

Flutter Version: Channel stable, 3.16.9
