我正在尝试运行 Flutter pub run build_runner build,生成用于导航的 router.g.dart 文件。
我已经运行了一个 build_runner clean,一个完整的项目,然后构建但没有运气。我正在学习一个教程,他似乎只是用我拥有的代码来运行它并且它很好。评论中似乎没有其他人有这个问题,我在网上找不到任何相关信息。
它没有说:

最佳答案
自 0.6.0
版本以来,auto_route package 中出现了一些重大变化。 ,最重要的是将路由声明方式从类字段更改为静态列表。您可以查看更多详情here .
因此,为了修复它,只需使用静态列表更新它,如下所示:
@MaterialAutoRouter(
routes: <AutoRoute>[
MaterialRoute(page: StartupView, initial: true),
MaterialRoute(page: HomeView),
MaterialRoute(page: CoverView),
],
)
class $Router {}
然后运行构建运行器命令:flutter pub run build_runner watch --delete-conflicting-outputs
另一个选项可以使用早期版本,如 0.5.0
,但建议保持更新,有关更多信息,请查看 auto route package 中的文档。 .
