Question

我正在开发一个使用本地数据库的Flutter项目。对于本地数据库，我正在使用sqflite插件https://pub.dartlang.org/packages/sqflite。我的应用程序运行正常，无需安装sqflite。但是，一旦我安装sqflite。它停止为ios运行。我收到以下错误消息。

导入产生1个错误。 ===具有配置调试功能的项目运行器的构建目标运行器=== 在/Users/user/Documents/DEVELOPMENT/Flutter_Dev/Flutter_project/FlutterDatabaseSQFLite-master/ios/Runner/AppDelegate.m中包含的文件中：1： / Users /用户/文档/DEVELOPMENT/Flutter_Dev/Flutter_project/FlutterDatabaseSQFLite-master/ios/Runner/AppDelegate.h:2:9：致命错误：未找到“ Flutter / Flutter.h”文件进口 ^ ~~~~~~~~~~~~~~~~~~ 产生1个错误。 / Users /用户/Documents/DEVELOPMENT/Flutter_Dev/Flutter_project/FlutterDatabaseSQFLite-master/ios/Runner/main.m:2:9：致命错误：找不到“ Flutter / Flutter.h”文件进口 ^ ~~~~~~~~~~~~~~~~~~ 产生1个错误。 ===具有配置调试功能的项目运行器的构建目标运行器=== ld：找不到文件：/Users/user/Library/Developer/Xcode/DerivedData/Runner-ctqhqjwcexxoquevqxydctppmagio/Build/Intermediates.noindex/Runner.build/Debug-iphonesimulator/Runner.build/Objects-normal/x86_64/AppDelegate.o clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）无法为模拟器构建应用程序。在iPhone 8 Plus上启动应用程序时出错。

。而奇怪的是，在发生此错误之后，如果我创建了一个新的flutter项目，它将给我以下错误。

该应用程序停止工作。这是flutter doctor命令的输出。
