RN 升级版本 特别繁琐，可能会丢失某一个库的版本调整
建议使用React Native官方推荐的升级助手：https://react-native-community.github.io/upgrade-helper/?
填写好 应用名称 ，包名，现在的RN 版本，所要升级的目标版本，
点击下边的按钮，就会帮你生成 你所想要 调整的代码部分。
使用以下命令会帮你列出，package.json 总需要升级的库的版本。

└── Re-run with '--write' to fix them info Visit https://aka.ms/align-deps for more information about align-deps.会列出 dependencies部分和 devDependencies部分 需要升级的版本号。
也可使用 命令自动修复：
npx @rnx-kit/align-deps --requirements react-native@0.80.0 --write
会自动帮你升级版本。
当然 除了这部分 还是有代码需要调整：
如果执行了以上命令，可忽略这部分的调整，
按照如图调整，
其中readme 部分可忽略。
重点来了：MainApplication 中的调整，移除不必要的引用，
在 onCreate 将原先的load方法替换：
| loadReactNative(this) |
android/build.gradle中的调整
替换版本号：
android/gradle/wrapper/gradle-wrapper.properties 调整gradle 版本。建议保持一致，使用8.14.3-bin
至于IOS 不太熟悉，很抱歉，可按照文档将重要文件进行替换，
Android 的，可以打开studio 先编译通过后 再进行运行打包。
建议重新依赖
yarn cache clean //清除缓存
yarn install //重新依赖
希望对大家有所帮助。
