英文:
Prevent re-initialization of Provider in Flutter web
问题
我目前遇到了一个关于我的Flutter web应用的问题。当我在新标签页中打开一个页面时，提供程序会重新初始化。这种行为类似于传统Web应用程序中页面刷新的方式。因此，我丢失了我的保存状态。有没有办法在不依赖本地存储的情况下保存它，并在所有标签页中访问它？请查看我用来在新标签页中打开页面的代码：
html.window.open('/#${Result.routeName}', "_blank");
英文:
I am currently experiencing an issue with my Flutter web app. When I open a page in a new tab, the providers reinitialize. This behavior is similar to how a page refresh works in a traditional web application. As a result, I have lost my saved state. Is there any way to save it without relying on local storage and access it across all my tabs? Please find below the code I am using to open the page in a new tab:
html.window.open('/#${Result.routeName}', "_blank");

作为一种替代的状态管理包，bloc 提供了一个解决方案，在 hydrated_bloc 包下可以找到你需要的东西。
但是在提供者方面，也许你可以使用 BroadcastChannel 类来解决问题，但创建一个本地存储会更加简单和有效。
你可以使用以下方式创建一个本地存储：
flutter_secure_storage:
或者
shared_preferences:
然后，你可以简单地创建一个方法来写入你希望在路由后恢复的状态。在新页面上，只需恢复这些状态并删除恢复存储。
这可能是最简单的解决方案，或者你也可以考虑迁移到 bloc。
祝你编码愉快 
英文:
As an alternative state management package, bloc offers a solution under hydrated_bloc package what you are looking for.
But on provider side maybe you can use BroadcastChannel class to solve that but creating a local storage would be much easier and effective.
You can create a local storage with
flutter_secure_storage:
or
shared_preferences:
Then you can simply create a method to write which states you want to recover after routing. After it on the new page just recover those states and delete that recovery-storage.
That will be the easiest solution I guess or you can move up to bloc.
Have a great coding session
