That means that the version of play services you have isn't being able to load up the qr analyzing libraries. Try updating to the most recent of play services and making sure you have a good internet connection - the first time you open the camera your phone downloads the required libraries to do the scanning (com.googl.android.gms.vision.dynamite.barcode:0). Unfortunately, there's not a whole lot I can do about it as it's a something internal to the google_mobile_vision library that's going wrong, but I realize it's not ideal at all because your end-users might experience the same thing.

Connecting while you have internet, and/or updating play services and restarting your device should hopefully resolve the issue.

Here's an issue someone else has seen: https://github.com/googlesamples/android-vision/issues/350, and there's a few more like it.

rmtmckenzie commented 5 years ago

BTW you can try adding this to your android manifest as should make the library download at install time rather than when the app first runs the qr scanner.

try flutter clean and build project again
