You can change the height by changing the minLines value just try this

               TextFormField(
                           keyboardType: TextInputType.multiline,
                           controller: _opTextController,
                           decoration: InputDecoration(
                               isDense: true,
                             border: OutlineInputBorder(
                               borderSide: BorderSide(color: Colors.black)
                             )

                           ),
                           maxLines: 5,
                           minLines: 3,
                           // controller: cpfcontroller,
                         )
