                        checkColor: Theme.of(context).cursorColor,
                        onChanged: (value) {
                          isChecked = !isChecked;
                          setState(() {});
                        },

                    ),

在CheckBoxListTile中，可能很难达到你想要的效果。但是，总是有一个解决方案，这就是使用Row()。此外，我们将使用FlatButton()来获得相同的效果。
这里的问题是，在FlatButton()中，您只需执行与Checkbox()中的onChanged相同的操作

解决方案

bool _myBool = false;

     Container(
        child: FlatButton(
          // here toggle the bool value so that when you click 
          // on the whole item, it will reflect changes in Checkbox
          onPressed: () => setState(() => _myBool = !_myBool),
          child: Row(
            mainAxisAlignment: MainAxisAlignment.start,
            children: [
              SizedBox(
                height: 24.0,
                width: 24.0,
                child: Checkbox(
                  value: _myBool,
                  onChanged: (value){
                     setState(() => _myBool = value);
                  }
                )
              ),
              // You can play with the width to adjust your
              // desired spacing
              SizedBox(width: 10.0),
              Text("افزودن به فهرست پرکاربردها")
            ]
          )
        )
      )

结果

如果你想让Checkbox()在右边，你可以把Text()和Checkbox()的位置交换一下，其余的都一样。

尝试将ListTileTheme替换为以下内容：

Padding(
  padding: EdgeInsets.only(right: 20.0),
  child: Row(
    mainAxisAlignment: MainAxisAlignment.end,
    children: <Widget>[
      Text(
        "افزودن به فهرست پرکاربردها"
      ),
      SizedBox(
        width: /* The spacing in between the checkbox and text */ 20,
      ),
      Checkbox(
        value: false,
        onChanged: (value) {},
      ),
    ],
  ),
),

这帮助我在ListTileTheme horizontalTitleGap中添加了以下内容：0,
