Present in the 0.3.0 version on Android, iOS works fine.

In version 0.3.0, the plugin uses references to FlutterActivity, that's why app throws an error if your MainActivity extends FlutterFragmentActivity.

It looks like this issue has been fixed (see https://github.com/CodingWithTashi/simple_barcode_scanner/pull/116), but a new version of the plugin has not been published yet.

I ended up using latest commit (for now) in my pubspec.yaml file like this:
