flutter inappwebview 中的 flutter 警告

Question

我正在我的 flutter 应用程序中实现一个 YouTube 播放器，当我运行它时，构建将失败并抛出贬值错误。

\n

我目前使用的是 2012 年中的 MacBook，所以我无法使用最新版本的 x 代码。我当前的版本是 Version 12.4 。因此，为了在 ios 上使用 flutter，我使用 flutter 2.5。

\n

所以现在当我尝试使用 youtube 播放器时它不会构建应用程序。

我正在使用的包是youtube_player_flutter: ^8.0.0. 该消息指示在应用程序 Web 视图中。

\n

if #available(iOS 10.0, *) {\n                configuration.ignoresViewportScaleLimits = options.ignoresViewportScaleLimits\n                \n                var dataDetectorTypes = WKDataDetectorTypes.init(rawValue: 0)\n                for type in options.dataDetectorTypes {\n                    let dataDetectorType = Util.getDataDetectorType(type: type)\n                    dataDetectorTypes = WKDataDetectorTypes(rawValue: dataDetectorTypes.rawValue | dataDetectorType.rawValue)\n                }\n                configuration.dataDetectorTypes = dataDetectorTypes\n                \n                configuration.mediaTypesRequiringUserActionForPlayback = options.mediaPlaybackRequiresUserGesture ? .all : []\n            } else {\n                // Fallback on earlier versions\n                configuration.mediaPlaybackRequiresUserAction = options.mediaPlaybackRequiresUserGesture\n            }\n

\n

以及应用程序网络视图选项

\n

if #available(iOS 10.0, *) {\n                realOptions["mediaPlaybackRequiresUserGesture"] = configuration.mediaTypesRequiringUserActionForPlayback == .all\n                realOptions["ignoresViewportScaleLimits"] = configuration.ignoresViewportScaleLimits\n                realOptions["dataDetectorTypes"] = Util.getDataDetectorTypeString(type: configuration.dataDetectorTypes)\n            } else {\n                realOptions["mediaPlaybackRequiresUserGesture"] = configuration.mediaPlaybackRequiresUserAction\n            }\n

\n

我取消注释platform: ios, '9.0'并在最后替换为

\n

post_install do |installer|\n  installer.pods_project.targets.each do |target|\n    flutter_additional_ios_build_settings(target)\n    target.build_configurations.each do |config|\n      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'\n    end\n  end\nend\n

\n

替换这些可以解决其他错误（不包含在这个问题中），但它似乎不适用于这些。我怎样才能解决这个问题？我之前没用过xcode。

我从过去两天就面临这个问题。

您不需要下载 X-code-14 版本。

只需打开 X-code 并运行显示错误的项目，然后单击错误并点击修复。
