You are building a fat APK that includes binaries for android-arm, android-arm64.
创新互联坚持“要么做到，要么别承诺”的工作理念，服务领域包括：成都网站制作、做网站、外贸营销网站建设、企业官网、英文网站、手机端网站、网站推广等服务，满足客户于互联网时代的商州网站设计、移动媒体设计的需求，帮助企业找到有效的互联网解决方案。努力成为您成熟可靠的网络建设合作伙伴！
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
To generate an app bundle, run:
flutter build appbundle --target-platform android-arm,android-arm64

To split the APKs per ABI, run:
flutter build apk --target-platform android-arm,android-arm64 --split-per-abi

Flutter-02编译器选择
1.打开 VS Code。
2.打开 查看 命令面板…。
3.输入 “install”，然后选择 扩展: 安装扩展(就是点击选择第一行内容)。
4.在扩展搜索输入框中输入 “flutter”，然后在列表中选择 Flutter 并单击 安装。此过程中会自动安装必需的 Dart 插件。（选择第一行并安装）
5.退出然后重新启动 VS Code。
1.打开 查看 命令面板…。
2.输入 “doctor”，选择 Flutter: Run Flutter Doctor。
3.打开 输出 (OUTPUT) 面板查看是否有错误，确保在不同的输出选项 (Output Options) 的下拉列表中选择了 Flutter。
我们在上篇文章已经用命令行创建了一个 my_app 的flutter项目了，这里我们就可以使用 vscode 打开看看了
创建新项目 ，则是在命令面板输 flutter , 选择 Flutter: New Application Project
运行项目 ，找到 VS Code 的状态栏(窗口底部蓝色的条)
1.打开 Android Studio。
2.打开插件设置（在 v3.6.3.0 以上的系统打开 Configure Plugins）。
这里需要先改一下网络请求的设置
3.然后搜索Flutter 插件，选择并点击 安装。
4.当弹出安装 Dart 插件提示时，点击 Yes。
5.退出重新启动编译器，然后在编译器主页面就可以看到多了了 create new flutter project 可供选择，代表flutter插件安装成功，我们试着点击来创建一个新项目。
2022-04-22iOS项目混编flutter，iOS真机debug模式下打不开flutter页面
最近项目中要集成flutter来进行混编，但是在集成后，突然遇到一个很神奇的问题，在debug模式下，用数据线连接真机打包可以打开flutter页面，但是一旦拔掉数据线，再打开flutter页面就不行了，开始以为是因为flutterSDK的原因，但是一查资料才发现，原来是因为debug模式下flutter实现了热重载，默认的编译方式是JIV,但是iOS14+之后的系统限制了JIV这种编译方式，所以连接Xcode重新run一个release包就可以了，因为flutter在release模式下的编译方式是AOT，iOS14+的系统是支持这种编译方式的，具体解决方案如下图
再运行就可以了。
当然还有另外一种解决方案，就是修改flutter的编译配置，强制设为release
Flutter工程化之iOS混编集成
在flutter官网上推荐了iOS项目中两种混编方式：
笔者在采用两种集成方式的过程中，因为iOS项目结构设计导致这两种简单的集成方式都有些麻烦，所以在实践中更改和优化了集成方式，使之在笔者的项目中能够更加简单和快速的集成。
问题：在不更改flutter tool中相关脚本的前提下，添加的Script Phase中的脚本相对路径错误，如果只是开发，手动更改下路径就可以了，但是在考虑到CI中不能每次在pod install之后都去更改，所以在开发调试中采用该集成方式，结合flutter attach的方式去调试。
通过编译相关的 xcframework + Cocoapods私有库的集成方式在CI中集成，这样QA的CI不需要配置flutter的相关依赖
根据flutter编译工具的提示： 上面的编译命令是打包flutter工程项目和插件的产物，在实际开发过程中可以发现是否引入了依赖Native的插件会导致贬义编译产物的不同。
根据上面的对比：
第一部分：基础的 Flutter Engine + Flutter App 编译后的产物 Flutter.xcframwork -- Flutter引擎的包 App.xcframework -- 工程项目对应的AOT的编译产物 第二部分：三方插件的注册中心 FlutterPluginRegistrant.xcframework -- 第三方插件的注册中心，其实是Native + iOS通信的集合 第三部分：依赖iOS Native的原生 FMDB . xcframwork path_provider_ios.xcframework sqflite.xcframework -- cached_network_image依赖的原生实现
根据上面的编译产物可以知道Flutter和App是编译后必有的包，后面的两个部分完全是服务于三方插件的，到这可以解答第二个问题：笔者App的混编过程中混编插件失效是因为笔者在NativeApp中重写了Flutter的容器，使用了FlutterEngineGroup动态创建多引擎去对应进入不同的功能模块，混合插件是因为重写过程中没有通过GeneratedPluginRegistrant注册插件，所以需要在Native的Flutter容器中注册插件，使之生效。
在这为什么使用commit的hash作为flutter-libs的依赖，因为pod install的时候会有缓存，除了版本好，commit hash也能保证每次CI编译通过 pod install 来更新flutter-libs依赖产物
完成！！！
【Android开发学Flutter】Xcode编译问题汇总
Xcode编译经常遇到各种问题，处理起来费时费力，挺打击学习积极性的。记录下这些问题，方便自己也帮助后来人。
编译的时候遇到：
网上有很多解决方法，我是用这个方法解决的：
编译的时候遇到：
解决办法：
Project - User-Defined - FLUTTER_ROOT 改成本地 flutter SDK路径
感谢 issues 上的小哥，给你个????
在项目目录下执行 flutter run 可以正常运行到手机，但是在Xcode build 还是有问题。
这时需要手动添加 FLUTTER_ROOT 到 User-Defined ：
添加之后：
就可以正常在Xcode build 安装到手机了。
flutter build ios 后出现：
pod install 后出现：
解决办法：
这是因为terminal没有走代理的流量，
使用 git config --global http.proxy "localhost:port" ，设置代理。
port是端口号，根据不同的vpn不一样，我的端口是10080。
执行 git config --global http.proxy "localhost:10080"
Xcode build 的时候出现：
解决办法：打开 ios/Podflie 文件：
关于 bitcode 的问题，我检查了下用到的第三方SDK，应该是百度地图的问题，我引入了个第三方插件（吐槽下没官方插件），百度地图有支持和不支持 bitcode 的两个SDK，我取消这个插件就没有报这个错了，奇怪的是，再次引入同一个插件，也可以正常打包，所以说这个问题还没有完全解决。
大家可以试下这个处理方法：
TARGETS - Build Seettings 搜 arm ，试一下把其他删除，只留下armv7跟armv7s或者只留下armv7
解决办法：
我是clean Xcode之后就可以了
解决办法：
用的是P12证书，改成手动签名：
