Flashlight plugin is not installed

Hey there!

I’m trying to get a simple console.log from this.flashlight.isSwitchedOn(); but I caught every time these warning:

console.warn: Native: tried calling Flashlight.isSwitchedOn, but the Flashlight plugin is not installed.
console.warn: Install the Flashlight plugin: ‘ionic cordova plugin add cordova-plugin-flashlight’

The Problem: I have installed the Flashlight Plugin.

Tried many times uninstall and install again, but I got this every time.
