如何减少flutter中Textfield的额外填充

Question

I have a Textfield which is having some default padding. I want to remove the top and bottom padding. How can I do it?

Below is the image

I tried giving maxLines property to Textfield but it didn't work.

                                   TextField(
                                         onChanged:
                                         bloc.changeRole,
                                         decoration: new InputDecoration(
                                             contentPadding:
                                             EdgeInsets.symmetric(
                                                 vertical: 0,
                                                 horizontal: 15.0),
                                             border: new OutlineInputBorder(
                                                 borderSide:
                                                 const BorderSide(
                                                     width: 2.0,
                                                     style:

                                                     .circular(
                                                     50.0)),

Just set isDense:true

TextField(
      decoration: new InputDecoration(
        isDense: true,
        contentPadding: const EdgeInsets.symmetric(vertical: 0, horizontal: 15.0),
      ),
),
