title: Is there any way to set elevation color in the RaisedButton widget?
body: <p>Here is an example:</p>
  <pre><code>RaisedButton(
   shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(10),
   ),
   padding: EdgeInsets.zero,
   elevation: 5, //Here is the elevation size
   onPressed: onPressed,
  ),
  </code></pre>
  <p>I guess it should work with this wrap <a href="https://api.flutter.dev/flutter/material/ElevatedButtonThemeData-class.html" rel="nofollow noreferrer">ElevatedButtonThemeData</a>, but it doesn't work</p>
  <pre><code>MaterialApp(
    title: 'Demo',
    theme: ThemeData(
      elevatedButtonTheme: ElevatedButtonThemeData(
        style: ButtonStyle(
          shadowColor: MaterialStateProperty.all&lt;Color&gt;(
            Colors.red, //Here
          ),
        ),
      ),
    ),
  </code></pre>
  <p>How to solve this?</p>
