Have the same issue

I think when we pop page that's using zoom widget would cause this error since there's no context available to force unwrap nullable value. To fix this, try to check it's mounted first.

  void recalculateSizes() {
    WidgetsBinding.instance?.addPostFrameCallback((_) {
     // --------------
      if (!mounted) {
        return;
      }
    // --------------
      final RenderBox parentRenderBox =
          _parentKey.currentContext!.findRenderObject()! as RenderBox;

Actually there's already PR about this #35 which can solve this issue. But the author @semakers might not publish it yet.
