如何让屏幕导航到其他屏幕从左到右开始？

Question

我在flutter web上工作。

我有两个屏幕，当我导航到第二个屏幕时，默认动画从底部开始，然后覆盖第一个屏幕。

我希望它从左到右滑动，当我点击导航按钮。

我已经在手机上看到了屏幕滑块，但这不是我想要的。

只是正常的。我看到有人这样做，但我找不到它

谢谢你

你可以复制粘贴运行完整的代码，下面 你可以使用包 https:/pub.devpackagespage_transition。 与 PageTransitionType.leftToRight 代码段

RaisedButton(
              child: Text('Left To Right Slide Second Page'),
              onPressed: () {
                Navigator.push(
                  context,
                  PageTransition(
                    type: PageTransitionType.leftToRight,
                    child: SecondPage(),
                  ),
                );
              },
            ),
