大佬教程收集整理的这篇文章主要介绍了如何实现 Flutter Provider 5.0.0 以将数据从其他一些子屏幕传递到带有底部标签栏的主屏幕,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
我有 2 个底部 Tabbar 导航,从第二个 Tabbar 转到另一个页面,如果我单击一个按钮,然后我必须将数据发送到主屏幕,即使用 ProvIDer 的第一个 Tabbar 中的页面,但正在获取
Error: Could not find the correct ProvIDer<ServiceReportProvIDer> above this ReportDetail Widget
This happens because you used a `BuildContext` that does not include the provIDer
of your choice. There are a few common scenarios:
- You added a new provIDer in your `main.dart` and performed a hot-reload.
To fix,perform a hot-restart.
- The provIDer you are trying to read is in a different route.
ProvIDers are "scoped". So if you insert of provIDer insIDe a route,then
other routes will not be able to access that provIDer.
- You used a `BuildContext` that is an ancestor of the provIDer you are trying to read.
Make sure that ReportDetail is under your MultiProvIDer/ProvIDer<ServiceReportProvIDer>.
This usually happens when you are creating a provIDer and trying to read it immediately.
