LinearGradient in Flutter?

I'm trying to use this code from Github in my app, but not sure why it shows some errors. A class to use later. It says The LinearGradient has a problem ( "colors, not defined ) but just checked the source code of Flutter and it has this property.

import 'package:flutter/material.dart';

class Palette {
  static const Color scaffold = Color(0xFFF0F2F5);

  static const Color facebookBlue = Color(0xFF1777F2);

  static const Gradient createRoomGradient = LinearGradient(
    colors: [Color(0xFF496AE1), Color(0xFFCE48B1)],
  );

  static const Color online = Color(0xFF4BCB1F);

  static const LinearGradient storyGradient = LinearGradient(
    begin: Alignment.topCenter,
    end: Alignment.bottomCenter,
    colors: [Colors.transparent, Colors.black26],
  );
}

This solution worked for me: https://github.com/flutter/flutter/issues/67084#issuecomment-702397222

in your pubspec.yml

change this to :

environment: sdk: ">=2.8.0 <3.0.0" and flutter pub get

i'm using android studio, then i invalidate cache and restart, done!

The latest Flutter version (1.22.0) is broken, I'd say.

My LinearGradient code worked until 10 minutes ago. Then I updated Flutter. After the update the same errors you see were coming up - no code changes were made.

However, the code still runs, regardless of the non-error, so that's the good news.
