flutter - Flutter ListView.builder 在警报对话框中不起作用

Question

我想在警报对话框中显示项目列表，以确认付款。但它不起作用，我尝试了很多解决方案。

AlertDialog(
      titlePadding: EdgeInsets.all(0),
      contentPadding: EdgeInsets.symmetric(horizontal: 10, vertical: 0),
      title: Text("Heading"),
      content: ListView.builder(
          shrinkWrap: true,
          itemCount: items.length,
          itemBuilder: (ctx, i) {
            return getRowWidget(i);
          }),
    );

这将解决您的问题，添加Container宽度。

     showDialog(
                context: context,
                builder: (context) => AlertDialog(
                  titlePadding: EdgeInsets.all(0),
                  contentPadding: EdgeInsets.symmetric(horizontal: 10, vertical: 0),
                  title: Text("Heading"),
                  content: Container(
                    width: double.maxFinite,
                    child: ListView.builder(
                        shrinkWrap: true,
                        itemCount: items.length,
                        itemBuilder: (ctx, i) {
                          return Text(items[i].toString());
                        }),
                  ),
                ),
              );

使用此代码。

       showDialog(
              context: context,
              builder: (context) => AlertDialog(
                titlePadding: EdgeInsets.all(0),
                contentPadding:
                    EdgeInsets.symmetric(horizontal: 10, vertical: 0),
                title: Text("Heading"),
                content: Container(
                  height: 100,
                  child: ListView.builder(
                      shrinkWrap: true,
                      itemCount: 1,
                      itemBuilder: (ctx, i) {
                        return Text("text");
                      }),
                ),
              ),
            );
