Flutter集成到Swift老项目 使用pod接入flutter
Xcode：Version 11.3.1 (11C504)
Swift：5.0
iOS项目地址
Flutter项目创建
cd some/path/
flutter create --template module flutter_yyframework文件路径如下：
cd 到你要混编的项目（YYFramework）同一个路径下 ,执行如下：
flutter create -t module flutter_yyframeworkPodfile 文件
#注意路径和文件夹名字正确无误 最后有一个反斜杠
flutter_application_path = '/Users/houjianan/Documents/GitHub/iOS/flutter_yyframework/'
load File.join(flutter_application_path, 'YYFramework', 'Flutter', 'podhelper.rb')
target 'YYFramework' do
install_all_flutter_pods(flutter_application_path)
end注：YYFramework 是iOS项目的文件名
添加好之后
pod install注意，如下错误：[!] InvalidPodfilefile: No such file or directory @ rb_sysopen - ./flutter_yyframework/.ios/Flutter/podhelper.rb.
需要在flutter_yyframework文件夹下执行以下命令，把.ios和.android等flutter配置生成出来。（打开模拟器。链接真机都可以。）
open -a Simulator
flutter run注意，如下错误是因为路径不对。
[!] Invalid `Podfile` file: cannot load such file -- path/to/flutter_yyframework/.ios/Flutter/podhelper.rb.
# from /Users/houjianan/Documents/GitHub/iOS/YYFramework/Podfile:7
