Works out of the box. No permissions are required since the CameraManager.setTorchMode() API (introduced in Android 6.0) does not require camera permission.
Optionally, you can declare the flash hardware feature in your AndroidManifest.xml:
<uses-feature android:name="android.hardware.camera.flash" android:required="false" />Works in Chrome and Chromium-based browsers on mobile devices. Uses the MediaDevices API with torch constraint. Call isAvailable() first to check if torch control is supported on the current browser/device.
