根因分析

使用未位于 Navigator 小部件下的 BuildContext 调用 Navigator.push/pop/replace，通常来自无路由的覆盖层、对话框或 MaterialApp 构建之前。

English

Navigator.push/pop/replace is called using a BuildContext that is not under a Navigator widget in the widget tree, typically from a context in a route-less overlay, dialog, or before MaterialApp is built.

解决方案

  1. Use Navigator.of(context, rootNavigator: true) to explicitly access the root navigator, or ensure the context is from a widget inside a MaterialApp/CupertinoApp.
  2. Wrap the navigation call in a post-frame callback to ensure the widget tree is built and the context is valid.

无效尝试

常见但无效的做法:

  1. 80% 失败

    The context may become stale or detach from the tree; the error persists if the widget is no longer in a route.

  2. 90% 失败

    The root context is above the Navigator; navigator operations require a descendant context.

  3. 70% 失败

    GlobalKey may still reference a disposed widget, yielding a context without a Navigator.
