  <p><strong>My current code :</strong></p>
  
  <pre><code>Container(
                    height: 1 / 3 * deviceSize.height,
                    width: double.infinity,
                    child: Text(
                      'Add New Location',
                      style: TextStyle(color: Colors.black, fontSize: 20.0),
                    ),
                    decoration: BoxDecoration(
                      borderRadius: BorderRadius.only(
                          bottomLeft: Radius.elliptical(300, 100),
                          bottomRight: Radius.elliptical(300, 100)),
                      color: Color(0xFFFAD02E),
                    ),
                  )
