Looks like setting
flashMode={Camera.Constants.FlashMode.torch}now works in SDK 36, but recording withflashMode={Camera.Constants.FlashMode.on}doesn’t turn on the flash, thanks for reporting againIm working in a bare react native project and i have updated expo-camera to version
11.2.1and the issue does not occur anymore. I think it has been solved in some update, because actually in iOS i can record videos with flash without any flicks or bugs. I suggest to update the package or the sdk in an expo managed project, in order to get this issue fixeddidn’t realize it worked for torch 😃 My work around right now is this before calling
recordAsync()this.setState({ isRecording: true, flashType: this.state.flashType === Camera.Constants.FlashMode.on ? Camera.Constants.FlashMode.torch: {} });
