tns plugin add @nstudio/nativescript-camera-plusYes the camera is rotated because it's a webcam to an emulator and it's just the way life works
The demo apps work best when run on a real device. You can launch them from the simulator/emulator however the camera does not work on iOS simulators. Android emulators will work with cameras if you enable your webcam.
The camera in your webcam being used on emulators will likely be rotated sideways (incorrectly). The actual camera output will be correctly oriented, it's only the preview on emulators that present the preview incorrectly. This issue shouldn't be present on real devices due to the camera being oriented correctly on the device vs. a webcam in a computer.
NOTE: You may want to run: npm run nuke first to clear and reset directories.
