OccludeWrapper: Getting "RenderBox was not laid out" issue in custom widgets

[jebstern]

I keep "RenderBox was not laid out" errors when using OccludeWrapper on custom widgets. Doesn't help if I give them height & width.

flutter_uxcam version: 2.5.2
Flutter SDK version: 3.22.0
Dart: 3.4.0

Error Message:

If I replace the Timer in OccludeWrapper --> initState() method to use WidgetsBinding.instance.addPostFrameCallback((_) {});, then the app works normally. (Haven't verified end results in UXCam dashboard yet)
