Flutter/iOS:如何在我的 NotificationServiceExtension Info.plist 文件中使用 pubspec.yaml 的应用程序版本?

问题描述

pubspec.yaml 中的 Flutter App 版本可以通过将条目更改为在常规的 iOS Info.plist 文件中使用

<key>CFBundleShortVersionString</key>
<string>$(FLUTTER_BUILD_NAME)</string>

<key>CFBundleVersion</key>
<string>$(FLUTTER_BUILD_NUMBER)</string>

但是,我创建了一个通知服务扩展来启用 FCM 富文本推送通知,它工作正常。但是当我将此扩展的 Info.plist 值更改为与上面相同的值时,应用程序失败并显示以下构建错误:

Unable to install /Users/pa/development/FlutterApps/myApp/build/ios/iphonesimulator/Runner.app on <ID>. This is sometimes caused by a malformed plist file:
ProcessException: Process exited abnormally:
An error was encountered processing the command (domain=IXErrorDomain,code=2):
Failed to create plugin placeholder for /Users/pa/development/FlutterApps/myApp/build/ios/iphonesimulator/Runner.app/PlugIns/NotificationService.appex
Failed to create promise.
Underlying error (domain=IXErrorDomain,code=2):

    Failed to create promise.
  Command: xcrun simctl install <ID> /Users/pa/development/FlutterApps/myApp/build/ios/iphonesimulator/Runner.app
Error launching application on iPhone 11 Pro.

如何在 Extensions Info.plist 文件中也使用相同的变量?我认为这只是一些配置,但我无法弄清楚。

谢谢!!

解决方法

Flutter 生成一个 xcconfig 文件,其中包含 FLUTTER_BUILD_NAMEFLUTTER_BUILD_NUMBER 等变量

要在扩展中使用这些变量,我们需要执行以下操作:

  1. 转到您的扩展程序 Info.plist 并添加这些变量。 Like this

捆绑版本字符串 -- $(FLUTTER_BUILD_NAME)

捆绑版本 -- $(FLUTTER_BUILD_NUMBER)

  1. 转到您的项目设置并为每个配置的扩展程序选择一个 Generated 配置文件。 Like this
