颤动中非动态容器小部件的水平旋转木马

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？

我试过使用 SingleChildScrollView() - 并在其中放置了一个 Row() 小部件，但是那没有做任何事情.. 没有滚动。

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'))),

]),

我希望每个容器都在同一行，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？

Answer 1

您可以复制粘贴运行下面的完整代码
您可以使用包 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

代码片段

 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'))),
            ]),
