Flutter iOS 应用程序在启动时显示白屏并在该屏幕上挂断

Question

我有一个使用 firebase auth 库的 flutter 应用程序。 当我启动它的 iOS 版本时，它向我显示一个空白的白色屏幕并在该屏幕上挂断。 我按照所有步骤将一些与 firebase 相关的标志添加到 Info.plist 中，例如 FirebaseScreenRecordingEnabled - NO、FirebaseScreenRecordingDeactiv - YES 以及一两个。 我试图清理构建文件夹和颤振缓存。 刚刚也尝试了以下答案： iOS Flutter with Firebase : white screen and SIGABRT in FlutterAppDelegate on launch

~/Documents/Work/Workspaces/flutter/myapp $ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):

仅供参考，我正在将 Android Studio 用于 Flutter 应用程序。

以下是来自 xCode 记录器的日志：

但到目前为止没有运气。 任何人都可以在这里帮助我。 谢谢

Answer 1

错误日志清楚地说

项目的 Bundle ID 与“GoogleService-Info.plist”中的 Bundle ID 不一致，或者如果您使用的是自定义选项，则与 options 中的 Bundle ID 不一致。 为了确保一切都可以正确配置，您可能需要使 Bundle ID 保持一致。 要继续使用此 plist 文件，您可以将应用程序的包标识符更改为“com.tethys.client”。 或者，您可以从https://console.firebase.google.com/下载与您的包标识符匹配的新配置文件并替换当前配置文件。

尝试从 iOS 项目替换您的GoogleService-Info.plist 。 确保它有一个有效的 Bundle ID

另外，请确保在创建存档或分发存档之前您是否正在运行以下命令。

flutter build ios --release

或者

flutter build ios

flutter build默认为--release 。

Answer 2

扑干净

颤振构建 --release

然后 XCode/存档

Answer 3

截至 2021 年 4 月 28 日，对我有用的方法（经过几天的斗争）：

在 AppDelegate.swift (flutter-project/ios/Runner) 中：添加以下两行：

FirebaseApp.configure()
GeneratedPluginRegistrant.register(with: self)

在终端：

颤振构建 ios

然后在 XCode 中运行你的项目

Answer 4

哦，我终于发现 iOS 14 及更高版本的设备存在 Flutter 框架问题，请在此处查看更多详细信息： https : //github.com/flutter/flutter/issues/60657#issuecomment-688478590

Answer 5

我遇到过这个问题。

我的方法是：

在 pubspec.yaml 文件中运行包升级

希望能帮到你。

Answer 6

可能是package_info_plus plugin ，调用PackageInfo packageinfo = await PackageInfo.from Platform();时出现白屏 runApp(App());之前的方法runApp(App());
