flutter boost 5.0.2 集成
背景：
直接下载了flutter boost main，所有代码。iOS项目构建不通过。

flutter boost
FlutterBoost 5.0.0 虽然是一个官方发布的正式版本，但它所属的版本区间 [4.5.0, 5.0.0) 被官方定义为了专用于适配鸿蒙（HarmonyOS）的版本

所以需降级到 4.3.2, 或者升级到 5.0.2

升级到5.0.2之后
先是
flutter 项目本身的依赖冲突，
使用 flutter outdated,
flutter pub upgrade --major-versions,
处理flutter 项目依赖冲突。

再重新安装 相关依赖。

然后pod install iOS项目。
报错：

 pod install
Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "image_picker_ios":
  In Podfile:
    image_picker_ios (from `.symlinks/plugins/image_picker_ios/ios`)

Specs satisfying the `image_picker_ios (from `.symlinks/plugins/image_picker_ios/ios`)` dependency were found, but they required a higher minimum deployment target.

其实是podfile 中的image_picker_ios和 platatform :ios, '11.0'冲突了。
需要升级配置platatform :ios, '15.0'

问题解决

之后，构建 XCode中 workspace.
发现：
很多flutter错误，可以查看Xcode编译错误：

排查后发现，还是 webview_flutter 的问题。
webview 示例中的版本都废弃了，官方使用了WebViewController，
使用阿里的灵码搞定。

lib/case/bottom_navigation_bar_demo.dart

lib/case/platform_view_perf.dart

lib/case/webview_flutter_demo.dart

lib/case/simple_webview_demo.dart

这四个文件中关于WebView的代码，全部替换为：

//lib/case/simple_webview_demo.dart 中
  final String viewType = '<simple-text-view>';
  //添加
  late final WebViewController controller;


  @override
  void initState() {
    super.initState();
    controller = WebViewController()        //添加  
      ..setJavaScriptMode(JavaScriptMode.unrestricted) //添加  
      ..loadRequest(Uri.parse(url));        //添加  
    // Enable virtual display.
    // if (Platform.isAndroid) WebView.platform = AndroidWebView();
  }

     child: WebView(        //删除
        initialUrl: url,    //删除

      child: WebViewWidget(     //添加  
        controller: controller, //添加  
  

//以下3个文件中，有类似操作
lib/case/bottom_navigation_bar_demo.dart

lib/case/platform_view_perf.dart

lib/case/webview_flutter_demo.dart

之后再运行 fultter：
flutter pub get
// 可选
flutter build ios //如果证书配置不正确，会失败。

xCode:
pod install

build.
项目成功运行。
