######Problem 1.上传App Store构建版本，上传成功，App Store Connect并不显示构建版本？
权限未配置齐全 升到iOS10之后，需要设置权限的有： 麦克风权限：Privacy - Microphone Usage Description 是否允许此App使用你的麦克风？ 相机权限： Privacy - Camera Usage Description 是否允许此App使用你的相机？ 相册权限： Privacy - Photo Library Usage Description 是否允许此App访问你的媒体资料库？ 通讯录权限： Privacy - Contacts Usage Description 是否允许此App访问你的通讯录？ 蓝牙权限：Privacy - Bluetooth Peripheral Usage Description 是否许允此App使用蓝牙？ 语音转文字权限：Privacy - Speech Recognition Usage Description 是否允许此App使用语音识别？ 日历权限：Privacy - Calendars Usage Description 定位权限：Privacy - Location When In Use Usage Description 定位权限: Privacy - Location Always Usage Description 位置权限：Privacy - Location Usage Description 媒体库权限：Privacy - Media Library Usage Description 健康分享权限：Privacy - Health Share Usage Description 健康更新权限：Privacy - Health Update Usage Description 运动使用权限：Privacy - Motion Usage Description 音乐权限：Privacy - Music Usage Description 提醒使用权限：Privacy - Reminders Usage Description Siri使用权限：Privacy - Siri Usage Description 电视供应商使用权限：Privacy - TV Provider Usage Description 视频用户账号使用权限：Privacy - Video Subscriber Account Usage Description
######Problem 2.上传App Store构建版本，上传成功，App Store Connect显示正在处理中，过一会版消失?
工程中引用权限插件有问题 预估为私有api访问 去除插件上传成功 权限处理插件 permission_handler: 2.1.2 提交应用到iTunes Connect时构建版本“正在处理”后直接消失——此构建版本无效
######Problem 3.Flutter不在代码中设置不能抓包？ Flutter中http请求抓包解决方案
######Problem 4.Error: Expected an identifier, but got ''. const flutter clean
######Problem 5.Flutter杂症（ flutter packages pub run build_runner build ） --delete-conflicting-outputs //清除之前生成的文件，如果直接运行下面的不行。可以先尝试运行这个 flutter packages pub run build_runner clean //可以直接运行这个 flutter packages pub run build_runner build --delete-conflicting-outputs Flutter杂症（ flutter packages pub run build_runner build ）

######Problem 6.Flutter在安卓部分真机上不显示图标(显示为flutter icon) 安卓系统图标缓存问题 切换主题即可 （究极大法：出厂重置）
######Problem 7.Flutter项目中在代码端判断当前运行模式并取不同的url地址
static String initHost() {
const String inProduction = const String.fromEnvironment("dart.vm.product");
if (inProduction == "true") {
// 线上地址
} else if (inProduction == "false") {
// 线下地址
} else {
// 测试地址
}
}
