我尝试将 maxLines 属性赋予 Textfield，但没有成功。

                                   TextField(
                                         onChanged:
                                         bloc.changeRole,
                                         decoration: new InputDecoration(
                                             contentPadding:
                                             EdgeInsets.symmetric(

只需设置isDense:true

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