循环时插入复选框

Question

创建这样的复选框：

 for (var a in user.poll.questions[i].options) {
        children.add(
          new Row(
            children: [
              new Checkbox(
                value: checkBoxValue,
                onChanged: (bool newValue) {
                  setState(() {
                    checkBoxValue = newValue;
                  });
                }
              ),
              new Text(a.text),
            ],
          ),
        );
      }

这将创建它：

这是我所需要的..但​​是问题是当一个被选中的所有内容将被更新并被检查并反转时...

我要检查一个..，只有这一项将被检查，我得到它的值..

该怎么做？是否有复选框ID或什么？

Answer 1

您可以保存选定的问题-类似于：

it('renders a filter tab with expected props after clicking', () => {
    const comp = shallowRender({});
    comp.find(FilterTab).simulate('click');
    expect(comp).toMatchSnapshot();
});

it('calls callback passed after clicking on filter tab', () => {
    const filterByNeedsReviewFn = jest.fn()
    const comp = shallowRender({ filterByNeedsReviewFn });
    comp.find(FilterTab).simulate('click');
    // let's ensure callback has been called without any unexpected arguments
    expect(filterByNeedsReviewFn ).toHaveBeenCalledWith(); 
});

UPD 进行多次检查：

1-设置列表而不是一个值

Question selectedQuestion = null;
.....

 for (var a in user.poll.questions[i].options) {
    children.add(
      new Row(
        children: [
          new Checkbox(
            value: selectedQuestion == a,
            onChanged: (bool newValue) {
              setState(() {
                selectedQuestion = a;
              });
            }
          ),
          new Text(a.text),
        ],
      ),
    );
  }

2-更改CheckBox行为

final List<Question> questionList = [];
