Could you provide more details about the section where this happened.

This usually happens when there is some nullable variable that has been used in another part of the codebase while it was still null. Or this could also happen as a result of an unknown bug in any flutter channels that is not stable.

Case 1: example

String? foo; // Nullable String

void main() {
  var len = foo!.length; // Runtime error: Null check operator used on a null value
}

If you think it is the other case, then try the following commands.

flutter channel stable
flutter upgrade
flutter clean
flutter pub cache repair
flutter clean
flutter pub get
flutter run

Hello @ShimronAlakkal this is a automatic error logging system, as it isn't directly produced by a dev there aren't any more infos then that it seems to be in ml_kit_scan_page.dart somewhere in line 150 or 143

[ShimronAlakkal]

could we close this issue then?

[M123-dev]

I mean it's a issue in our code. Something what we don't want is happening so I'd keep it open

[ShimronAlakkal]

My bad. I thought ml_kit_scan_page.dart was a page from a package in pub.dev and not from the smooth_app code. So you know.

It's gone from sentry 😄
