🐛 Crash when scanning barcodes + repeatedly mounting the camera.

[daankennes]

What's happening?

The screen shared below is being mounted and unmounted multiple times. After being mounted a random number of times (around 5 leads to the crash for me), the app crashes without providing any additional information (it simply closes). I've only run into this on Android.

Thank you for your work on this package!

Stacktrace looks pretty similar to #2116?

[DevUser0491]

Hello @daankennes.
Your code is a good example with cornerPointSets. Is it possible to do a one square frame instead of 4 corners? Like this?

[daankennes]

@marcshilling, thank you - yes that's the same thing. Seems like I did not go through open issues very well.

@DevUser0491: that is off-topic, but yes, just use CodeScannerFrame's width and height properties.

[daankennes]

#2213 fixed it for me.

[ArturoTorresMartinez]

Any update on this? I tried that PR but the build throws an error
