EasterEggTrigger class

The EasterEggTrigger widget allow you to easily call a function when a combination of gestures have been detected on a given widget

Please find a working and concrete example here: https://gitlab.com/mrdiez/flutter_scaffold in the ./lib/components/images/main.logo.dart file

Sample call :

    EasterEggTrigger(
      action: () => print("Easter Egg !!!"),
      child: Image.network('https://picsum.photos/250?image=9')
    );

This example will print "Easter Egg !!!" in your console when you do these gestures on the image:

Swipe Up, Swipe Up, Swipe Down, Swipe Down, Swipe Left, Swipe Right, Swipe Left, Swipe Right, Tap, Long Press

Yes this is the famous Konami code: ↑ ↑ ↓ ↓ ← → ← → B A note that I replaced B button by Tap and A button by Long Press
