Free tweak to make your flashlight vibrate when turning on or adjusting the brightness of it in the control center. If you hold your finger on it in the expanded CC module you get a constantly vibrating flashlight. Also has option to vibrate brightness and volume sliders.

Configure options from settings. Works on all devices with haptic feedback on iOS 11-13.3 or higher, including A12+ A13.

I open sourced this tweak for any beginner developers hoping to see how to make a simple haptic feedback tweak like this can be made.
