推荐答案

虽然您可以同时使用操作和目的地来导航屏幕，但还是有区别的.

Though you can able to navigate screens using both actions and destination but there is difference.

根据谷歌按操作导航比按目的地导航有以下优点:

1) 您可以通过您的应用可视化导航路径

1) You can visualize the navigation paths through your app

2) Actions 可以包含你可以设置的附加关联属性，例如过渡动画、参数值和 backstack 行为

2) Actions can contain additional associated attributes you can set, such as a transition animation, arguments values, and backstack behavior

3) 您可以使用插件安全参数进行导航

3) You can use the plugin safe args to navigate
