In new Flutter, WidgetsBinding.instance will never be null. So, 4 annoying warnings poped up. Pls, fix these[0.2.2]

Sorry for being lazy, but let me skip how to reproduce this because I think this is just to update and then to run.
Same Issues on a different rep: google/charts#735

I'm using visibility_detector 0.2.2 from https://pub.dev/packages/visibility_detector/install

This was fixed already by #325.

[Wissperwind]

And is a Version including this fix already released?

[igolubic]

Any updates regarding this?

Bump...

Bump, it would be nice to see this fixed as this package is owned by google

As I mentioned earlier, this should already be fixed, which is why this issue is closed. Have you tried the latest version of visibility_detector (0.3.3)?
