LateInitializationError: Field 'alphaAnimation' has not been initialized.

[AlexanderShirokih]

I got the next error after updating to version 2.0.0:

The following LateError was thrown building AvatarGlow(dirty, state: _AvatarGlowState#4a8d4):
LateInitializationError: Field 'alphaAnimation' has not been initialized.

The relevant error-causing widget was: 
  AvatarGlow 
When the exception was thrown, this was the stack: 
#0      _AvatarGlowState.alphaAnimation (package:avatar_glow/avatar_glow.dart)
#1      _AvatarGlowState.build (package:avatar_glow/avatar_glow.dart:140:18)
#2      StatefulElement.build (package:flutter/src/widgets/framework.dart:4704:27)
#3      ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:4587:15)
#4      StatefulElement.performRebuild (package:flutter/src/widgets/framework.dart:4759:11)

The error occurs when I start with animate: false

I tried running the example and it works fine.
Can you let me the output of flutter doctor -v?
I guess this something to null safety on older flutter sdks

Here you go. I think everything is ok...

Hi @nurassylive Thanks for sharing information.
