Question

我正在尝试构建容器小部件的水平轮播-即用户只需水平滚动即可查看我拥有的6个容器小部件。

我该如何实现？

我已经尝试过使用SingleChildScrollView（）-并在其中放置了Row（）小部件，但这没有任何作用..没有任何滚动。

Row(children: [
Container(child: Card(child: Text('Unit 1'))),
Container(child: Card(child: Text('Unit 2'))),
Container(child: Card(child: Text('Unit 3'))),
Container(child: Card(child: Text('Unit 4'))),
Container(child: Card(child: Text('Unit 5'))),
Container(child: Card(child: Text('Unit 6'))),

]),

我希望每个容器都位于同一行，并且最终用户能够水平滚动以查看每个项目，

您将如何实施？

您可以在下面复制粘贴运行完整代码
您可以使用软件包https://pub.dev/packages/flutter_mobile_carousel
您可以使用rowCount来定义需要同时显示多少个项目

代码段

 Carousel(rowCount: 4, children: [
              Container(child: Card(child: Text('Unit 1'))),
              Container(child: Card(child: Text('Unit 2'))),
              Container(child: Card(child: Text('Unit 3'))),
              Container(child: Card(child: Text('Unit 4'))),
              Container(child: Card(child: Text('Unit 5'))),
              Container(child: Card(child: Text('Unit 6'))),
            ]),
