我想删除 Row 小部件中两个 IconButton 之间的一些额外空间我尝试了更多，但仍然无法删除小部件之间的空间

Column(
  children: <Widget>[
    Row(
      mainAxisAlignment: MainAxisAlignment.spaceBetween,
      children: <Widget>[
        Text("Home",
          style: TextStyle(
            fontWeight: FontWeight.bold,
            fontSize: 15,
            color: Colors.black
          )
        ),
        Row(
          mainAxisAlignment: MainAxisAlignment.end,
          children: <Widget>[
            IconButton(
              icon: Icon(
                Icons.edit,
                color: Colors.black,
                size: 20,
              ),
              onPressed: () {
                IntelUtility.navigateToScreen(
                  context, EditHomeAddressScreen()
                );
              },
            ),
            IconButton(
              icon: Icon(
                Icons.delete,
                color: Colors.black,
                size: 20,
              ),
              onPressed: () {},
            ),
          ],
        ),
      ],
    ),
  ],
),

请帮助解决这个问题，我遇到了麻烦:(

在我的代码中Container(height: 1, color: UtilColors.grey),没有给出预期的输出

Container(
              margin: EdgeInsets.only(left: 52, right: 48),
              child: DropdownButton<String>(
                isExpanded: true,
                //Container(height: 1, color: UtilColors.grey),
                value: _selectedUser,
                items: _userTypes.map((String value) {
                  return new DropdownMenuItem<String>(value: value, child: new Text(value));
                }).toList(),
               /* decoration: InputDecoration(contentPadding: EdgeInsets.only(left: 15), suffixIcon: IconButton(onPressed: () {
                 // _userTypes.map((String value){return new DropdownMenuItem<String>(value: value, child: new Text(value));}).toList();
                   }, icon: Icon(null),)),*/
                icon: Icon(Icons.keyboard_arrow_down),
                hint: Text(UtilString.userType),
                onChanged: (value) => setState(() => _selectedUser = value),
              ),
            ),
