here, I created _inputfields Widget for the text fields and I just want to remove underlines from the text fields but it doesn't allow me to do that

Question

              _inputfields(context,"Username",_userName.focusNode,                 
                           _userName.mycontroller,false),

              _inputfields(context, "Password", _password.focusNode,
                           _password.mycontroller, true),

...........

Widget _inputfields(BuildContext context, String hinttext, FocusNode _focusnode, TextEditingController _controller, bool obscure, {bool optional = false}) { return Container( decoration: BoxDecoration( color: Colors.purple,

  borderRadius: const BorderRadius.all(Radius.circular(100)),


),

You need to apply a TextStyle without an underline like so:

TextStyle(decoration: TextDecoration.none);

Now Assuming you are using a TextFormField:

    TextFormField(style: TextStyle(decoration: TextDecoration.none),
                  decoration: InputDecoration(labelText: 'Enter your sample Username'), 

                  validator: (input) { return null;});
