Change the color and the width to your likings providing errorBorder and focusedErrorBorder inside InputDecoration as decoration for TextFormField:

TextFormField(
        decoration: InputDecoration(
          focusedErrorBorder:UnderlineInputBorder(
            borderSide: const BorderSide(color: Colors.blue, width: 2.0))
          errorBorder: UnderlineInputBorder(
            borderSide: const BorderSide(color: Colors.blue, width: 2.0),
          ),
        ),
      ),
