title: Flutter: Showing both helpText and labelText in TextFormField
body: <p>I am trying to build a login page using Flutter.</p>
  
  <p>I want to have both hintText and labelText shown for the TextFormField that I'm using, however it only shows me the labelText when I click on the field, that is, when the cursor is in that field.</p>
  
  <pre class="lang-dart prettyprint-override"><code>  TextFormField(
      keyboardType: TextInputType.emailAddress,
      decoration: const InputDecoration(
      hintText: 'example@email.com',
      labelText: 'Username',
      labelStyle: TextStyle(
        color: Colors.blue,
        ),
      ),
    );
  </code></pre>
