flashlight with the flash of the camera

as I can make a program in App Inventor to handle the camera flash as a flashlight

--

Developers cannot use the camera flash as a flashlight using App Inventor programming.  Not possible.

Perhaps, try something like this if you want a kind of flashlight app?:

You need a button, a Canvas (with dimensions about 320 x 400 pixels) and some imagination. Clicking the Turn on button makes the screen bright.  Click again and the device screen goes dark.
