NeumorphicAppBar causing: The getter 'current' was called on null.

[havocy28]

I'm trying to use the NeumorphicAppBar using Flutter-Neumorphic 3.02

The line causing the error is when building a Scaffold and the line: appBar: NeumorphicAppBar()

I saw a reference for buttons and this requiring it to be wrapped in a theme, but could not find any examples.

Here is the stacktrace:
