null safety ?

[yoirgla]

Here's the message a I get when installing the plugin :)

/c:/Flutter/.pub-cache/hosted/pub.dartlang.org/cyclop-0.6.1/lib/src/widgets/color_button.dart:111:29: Error: Method 'insert' cannot be called on 'OverlayState?' because it is potentially null.

• 'OverlayState' is from 'package:flutter/src/widgets/overlay.dart' ('/c:/Flutter/packages/flutter/lib/src/widgets/overlay.dart'). Try calling using ?. instead. Overlay.of(rootContext).insert(pickerOverlay!); /c:/Flutter/.pub-cache/hosted/pub.dartlang.org/cyclop-0.6.1/lib/src/widgets/eyedrop/eye_dropper_layer.dart:123:25: Error: Method 'insert' cannot be called on 'OverlayState?' because it is potentially null.

I hope it helps
