I didn't test it on iOS yet

Actually neither TorchCompat.turnOn or tornOff works in Android

I think that the problem is that I'm trying to toggle the flash with the camera open...

Anyway flutter clean has no effect, you example app works and the device is a Huawei/Honor JSN-L21.

Indeed, this project can not work if you have another camera session opened. Android doesn't allow to have multiple instances at the same type.

I close the issue, since it's not related to the plugin itself. Please open a new one, if necessary :)
