title: How to create title in a box of TextField in Flutter?
body: <p>I want to create a <a href="https://api.flutter.dev/flutter/material/TextField-class.html" rel="nofollow noreferrer">TextField</a> as below:</p>
  <p><a href="https://i.stack.imgur.com/oOSex.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oOSex.png" alt="TextField" /></a></p>
  <p>I'm using this code:</p>
  <pre><code>       TextField(
            decoration: InputDecoration(
              contentPadding: EdgeInsets.all(20.0),
              labelText: &quot;Last Name&quot;,
              fillColor: Colors.transparent,
              border: OutlineInputBorder(
                borderRadius: BorderRadius.circular(25.0),
                borderSide: BorderSide(),
              ),
            ),
            keyboardType: TextInputType.emailAddress,
            style: new TextStyle(
              fontFamily: &quot;Poppins&quot;,
            ),
          ),
  </code></pre>
  <p>But It did not match with my expectations:</p>
