要求：
- Macos 已经配置好flutter开发环境；
- 支持Cocopods
可用如下命令查看Flutter是否配置成功
flutter doctor -v
如果终端打印如下，基本就OK了,Android的环境不用管，iOS可以就行；

问题
很久之前，也不能说很久，大概2个月前吧，公司决定未来要迁移到跨平台开发中，需要拿APP部分功能做一个尝试，看实际效果，然后我就看了下Flutter，按照Flutter中文网配置了开发环境，并且编译了一个 Hello Word 示例程序，成功运行；
项目组专门有一个同学负责写Flutter功能模块，我只需要集成并且跟Flutter数据交互，完成业务即可；
问题就出在这儿，我把Flutter模块更换成公司私有仓库时，更新代码，执行编译打包，发现Xcode编译通过，但是，Flutter无法渲染界面；我就很崩溃；重新查了下资料，发现网上用Pod集成Flutte的资料很少，很多的是，手动集成；
手动集成
手动集成，真是太不方便了，可以看看这个文章:iOS老项目集成Flutter（iOS混编Flutter),t太繁琐了，各种配置，如果你喜欢手动的话，就看那个文章就可以；
现在项目基本都是模块化，Flutter基本也是以Framework的形式引入在项目中，如果Flutter模块更新后，我们只需要执行 pod 更新一下，就可以了，真是太方便了；
Pod集成
- 在 Podfile 中，引入 Flutter 模块，具体就是下面两行代码
## Flutter 模块的路径
flutter_application_path = '/Users/ly/Desktop/所有/项目/APP/fighting_flutter_common_user'
eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)
加完后，你的Podfile大概就是下面这个样子的：
target 'fireCommonUser' do
# Uncomment this line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!
# Pods for FireControl
pod 'AFNetworking'
pod 'AMapLocation'
pod 'AMap2DMap'
pod 'AMapSearch'
pod 'MQTTClient'
## Flutter 模块的路径
flutter_application_path = '/Users/ly/Desktop/所有/项目/APP/fighting_flutter_common_user'
eval(File.read(File.join(flutter_application_path, '.ios', 'Flutter', 'podhelper.rb')), binding)
target 'fireCommonUserTests' do
inherit! :search_paths
# Pods for testing
end
target 'fireCommonUserUITests' do
inherit! :search_paths
# Pods for testing
end
end
- 可用如下命令更新Pod，会自动生成 flutter.framework
pod update –verbose –no-repo-update
- 增加编译选项
打开iOS项目，选中项目的Build Phases选项，点击左上角+号按钮,选择New Run Script Phase,将下面的shell脚本添加到输入框中：
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" build
"$FLUTTER_ROOT/packages/flutter_tools/bin/xcode_backend.sh" embed
具体如下：
结束
Pod集成到这里就结束了，真的很方便，Flutter 功能更新后，我这边就一个 Pod update 就好了；
如果需在项目中调用Flutter模块，并且跟Flutter进行数据交互，比如，
- Flutter怎么获取通讯录权限；
- 获取到的通讯录以什么样的格式传递呢
后面会专门整理一片文章介绍；
最后有问题欢迎大家留言讨论；
