No named parameter with the name 'nullOk' on Flutter Channel greater than Stable version

Hi! First of all, congrats for the awesome plugin created, it really is amazing all the functionalities that gave :)

Recently i implement your plugin into a custom plugin named: formio_flutter. But suddenly, i receive an error saying the following:

/usr/local/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_neumorphic-3.0.3/lib/src/widget/app_bar.dart:147:57: Error: No named parameter with the name 'nullOk'. final ScaffoldState scaffold = Scaffold.of(context, nullOk: true);

I don't know if there's an update about this issue or if is solved on another version.

This is my flutter version:

Flutter` (Channel beta, 1.24.0-10.2.pre, on Linux, locale en_US.UTF-8)

As an interim fix until the package support null safety you can edit the app_bar.dart file (line 147) in the package from this:

final ScaffoldState scaffold = Scaffold.of(context, nullOk: true);

to this

final ScaffoldState scaffold = Scaffold.of(context);

PS. This is a temp fix

Well, that's good to know about that temporary fix. But is kind of weird that this only happens on flutter versions above stable. 🤔

@Crdzbird I think they implemented a fix but their CI/CD build failed to publish so it works for me using this in my pubspec:

flutter_neumorphic: git: url: git://github.com/Idean/Flutter-Neumorphic.git

on version: Flutter 1.26.0-2.0.pre.339 • channel master • https://github.com/flutter/flutter.git Framework • revision 339216d186 (3 days ago) • 2021-01-14 06:45:14 -0800 Engine • revision 1b5e16cda2 Tools • Dart 2.12.0 (build 2.12.0-223.0.dev)
