You can use enabledBorder like this:

 Widget TextBox() => Container(
    child: Row(mainAxisAlignment: MainAxisAlignment.center, children: [
      Container(
          height: 60,
          width: 300,
          child: TextField(
            decoration: InputDecoration(
                enabledBorder: const OutlineInputBorder(
                  borderSide: const BorderSide(color: Colors.white, width: 0.0),
                ),
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.circular(15),
                ),
                hintText: 'Enter Name',
                fillColor: Colors.white,
                filled: true
                // Border

                ),
          )),
    ]),
  );
