how to add custom color to flutter? : <p>i want to change the color of appbar and use a custom color for it, i tried many options but none seem to work.
Is there any thing im missing?</p>

<pre><code>import 'package:flutter/material.dart';

final ThemeData CompanyThemeData = new ThemeData(
  brightness: Brightness.light,
  primaryColorBrightness: Brightness.light,
  accentColor: CompanyColors.black[500],
  accentColorBrightness: Brightness.light
);

class CompanyColors {
  CompanyColors._(); // this basically makes it so you can instantiate this class

 static const _blackPrimaryValue = 0xFF000000;

  static const MaterialColor black = const MaterialColor(
    _blackPrimaryValue,
    const &lt;int, Color&gt;{
      50:  const Color(0xFFe0e0e0),
      100: const Color(0xFFb3b3b3),
      200: const Color(0xFF808080),
      300: const Color(0xFF4d4d4d),
      400: const Color(0xFF262626),
      500: const Color(_blackPrimaryValue),
      600: const Color(0xFF000000),
      700: const Color(0xFF000000),
      800: const Color(0xFF000000),
      900: const Color(0xFF000000),
    },
  );
}
</code></pre>

<p>and then i have used it in main.dart as</p>

<pre><code>Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Demo',
      theme: new ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or press Run &gt; Flutter Hot Reload in IntelliJ). Notice that the
        // counter didn't reset back to zero; the application is not restarted.
        primarySwatch:Theme1.CompanyColors.black[50],
      ),
      home: new MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
</code></pre>

<p>but after execution it says </p>

<blockquote>
  <p>type Color is not of subtype MaterialColor</p>
</blockquote>
