title: What's the best practice to keep all the constants in Flutter?
body: <p>What's the best programming practice to create a constant class in Flutter to keep all the application constants for easy reference?</p>
  <p>I know that there is <code>const</code> keyword in Dart for creating constant fields, but is it okay to use <code>static</code> along with <code>const</code>, or will it create memory issues during runtime.</p>
  <pre><code>class Constants {
    static const String SUCCESS_MESSAGE = &quot;You will be contacted by us very soon.&quot;;
  }
  </code></pre>
