记录一次flutter项目更新到3.27

本人小白，正在学习flutter，之前看见一个大佬发的joker fun（段子乐）Flutter仿写段子乐app来咯～Flutter仿写段子乐app，项目整体基于GetX实现路由跳转、依赖注入、状态管理 - 掘金的项目，下载下来后一直没时间看，最近打开编译发现一堆问题，最后总结两个路线，第一条是尽可能最小改动运行起来，不保证第三库最新，第二条是保证所有库最新以及运行起来，所以在解决方案上有2条路本地环境：

android studio：最新LadyBug 2024.2.1 patch3
flutter 3.27.1
dart 3.6.0
kotlin 1.9.23

打开项目，打开控制台，运行flutter pub get 运行flutter run -v ，这里报了很多错，一个个看

DecoderCallback类找不到，这是因为在flutter 3.16移除了这个类，详情看3.16.0 release notes | Flutter，然后我发现并没有主动获取photo_manager这个库，它是从何而来呢？在官方plugin商店搜索集成这个库的库：然后我发现了wechat_assets_picker，这个库也集成了，那解决方式就像之前说的有两条：
【最小改动】就是添加photo_manager并且版本为3.0.0，不要升级太高，可能会出另外的问题(~~当然你可以试试~~ )，版本问题也可以看看官方：flutter_photo_manager/MIGRATION_GUIDE.md at main · fluttercandies/flutter_photo_manager · GitHub 再次运行flutter pub get和run -v gradle版本问题，compileSdkVersion 33改为34，gradle改为8.3-all，build gradle为8.1.1，kotlin为1.8.22。第三方库的改动：

注释签名

统一设置namespace: 代码修改：到这应该就没问题了，接下来在这基础上把所有第三库更新到最新，如果你没有特别需要，就不用往下看了

注：最新库有新的问题，后面说

【更新到最新】基本上每个都有更新，这里重点说下pull_refresh，有个flutter3版本，所以需要更新： json_serizble这个库最新和retrofit冲突，所以注释掉：全体更新pull_refresh build_runner: 完整如下：
