致命错误：未找到 Flutter 2.2.3 的“Flutter/Flutter.h”文件答案

【问题标题】：fatal error: 'Flutter/Flutter.h' file not found for Flutter 2.2.3致命错误：未找到 Flutter 2.2.3 的“Flutter/Flutter.h”文件
【发布时间】：2021-09-29 11:25:33
【问题描述】：

自从我升级到 Flutter 2.2.3 后，我就一直遇到这个问题

致命错误：找不到“Flutter/Flutter.h”文件 #import "Flutter/Flutter.h"

两个插件

共享首选项
URLLauncher

我的 pod 文件的后安装是

post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
end
end
end

但是，当我将其更改为

post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end

它给出了以下错误

iOS 模拟器部署目标“IPHONEOS_DEPLOYMENT_TARGET”设置为 8.0，但支持的部署目标版本范围为 9.0 到 14.5.99。

我已经尝试了所有方法，包括删除 Podfile、Podfile.lock、Pods 文件夹、升级 Flutter、将频道从 Stable 更改为 Master 到 Beta、创建新项目和复制 iOS 文件夹

没有任何效果，我已经被困了好几天了。

感谢任何帮助

谢谢！

我尝试了很多解决方案，但只有一个对我有用。

rm -rf ios
flutter create .
flutter pub get

我会在iOS和其他一些东西上丢失应用程序图标，但如果你使用git，可以轻松恢复你需要的文件。
