  Gender _gender = Gender.male;

I have tried giving my Column a Fixed height and width but still no luck.

child: Expanded(
          child: Container(
            width: double.infinity,
            height: 200,
            child: ListView(
              children: [
                InputField(
                  icon: Icon(
                    Icons.person,
                    color: Colors.white,
                  ),

Just in case any other person get stuck with this, I was able to make this work by wrapping my Row widget with IntrinsicHeight and also wraping each RadioListTile widget with Flexible. I was able to find help here. BoxConstraints forces an infinite width

class EditUserProfile extends StatefulWidget {
  static String id = 'edit-profile';
  @override
  _EditUserProfileState createState() => _EditUserProfileState();
}

enum Gender { male, female }

class _EditUserProfileState extends State<EditUserProfile> {
  Gender _gender = Gender.male;

  @override
