Question

启动Flutter应用程序时出现以下错误：

══╡ EXCEPTION CAUGHT BY FLUTTER FRAMEWORK ╞═════════════════════════════════════════════════════════
The following message was thrown:
Could not navigate to initial route.
The requested route name was: "/animals/cats/lolcats"
The following routes were therefore attempted:
 * /
 * /animals
 * /animals/cats
 * /animals/cats/lolcats
This resulted in the following objects:
 * MaterialPageRoute<dynamic>("/", animation: null)
 * MaterialPageRoute<dynamic>("/animals", animation: null)
 * null
 * MaterialPageRoute<dynamic>("/animals/cats/lolcats", animation: null)
One or more of those objects was null, and therefore the initial route specified will be ignored and
"/" will be used instead.
════════════════════════════════════════════════════════════════════════════════════════════════════

我已经声明了路线/animals/cats/lolcats：

'/animals': (context) => AnimalsScreen(context),
'/animals/dogs': (context) => DogsScreen(context),
'/animals/cats/lolcats': (context) => LolcatsScreen(context),

并将我的initialRoute设置为

initialRoute: '/animals/cats/lolcats',

为什么即使声明了路由也出现上述错误？

我认为错误日志非常明确。

由于您使用'/'划分了路线，因此将其解释为“子路线”。实际上，它试图一个接一个地通过这些路线：

* /
* /animals
* /animals/cats
* /animals/cats/lolcats

由于未定义/animals/cats，因此t出现错误，然后返回初始路径：/

如果您想解决此问题，请使用下划线重新命名您的路线，如下所示： /animals_cats_lolcats 因此，它将不会尝试获取不存在的/animals/cats

颤振错误“无法导航到初始路线”
