BarCodeScanner size on Android


i can’t set fixed width and height of BarCodeScanner component on Android… i’ve create a new project and paste this code:

The BarCodeScanner change dimensions… sometimes the black area is square, sometimes is rectangular (after app reload)



Hey @shork,

What SDK version are you developing with? This Snack must be quite old as it was pushed to SDK25 when I opened it. I upgraded it to SDK31, made the changes needed due to deprecations (no more torchMode and onBarCodeRead is changed to onBarCodeScanned) and I’m not experiencing any issues with the size changing.




I use expo 31.0.2, i’ve this issue after upgrade expo from SDK30, only on Android devices
