Before submitting a new issue
- I tested using the latest version of the library, as the bug might be already fixed.
- I tested using a supported version of react native.
- I checked for possible duplicate issues, with possible answers.
Bug summary
Hey there, first of all thanks for this great library ❤️
I'm facing a quite weird behaviour when using the app in landscape mode, the CameraView component shows a rotated image, making it quite counterintuitive (albeit pretty fun 🙃 ) to align a bar code in the middle of the view.
Using the following reference picture
Pointing an iPad with an app in landscape right orientation (USB-C port on the right/ apple pencil upside) gives the following view
In landscape left orientation, I get the following preview
Workarounds
Flipping the view manually using a react-native transform enables me to flip the view by myself, however the behaviour of the transform trop is weird - it seems to apply the rotation twice, so I need to use half the actual values!
- In right landscape, I'm rotating the view by 135 deg
- In left landscape, I'm rotating the view by 45 deg
That gives a sort of workaround however it requires me to detect the orientation using another library, and I'm not sure if I need to do the same on Android...
