Could not build the application for the simulator.
Error launching application on iPhone SE (2nd generation).

这些是我在这个应用程序中使用的包：

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter
  json_annotation:
  audioplayers: ^0.15.1
  wakelock:
  shared_preferences:
  vibration: ^1.4.0
  flutter_local_notifications: ^1.1.5+1
  flutter_icons: ^1.0.0+1
  flutter_launcher_icons: ^0.7.4
  url_launcher: ^5.4.2
  get: ^1.15.2

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  build_runner:
  json_serializable:
  flutter_test:
    sdk: flutter

我也尝试创建一个新项目并将之前项目中的所有代码复制到新项目中，但仍然无法正常工作。谁能帮我解决这些问题。

【问题讨论】：

你能发布flutter --version的输出吗？

【参考方案1】：

您的问题似乎与 get 包有关。你落后了很多版本。较新的版本在调用super.install() 时不传递参数，这是您的错误的来源。

升级到更新版本的软件包可能会解决您的问题。除非您有理由不购买最新版本，否则我建议您将 pubspec.yaml 中的 get: ^1.15.2 行更改为 get: ^3.2.2，如下所示：

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter
  json_annotation:
  audioplayers: ^0.15.1
  wakelock:
  shared_preferences:
  vibration: ^1.4.0
  flutter_local_notifications: ^1.1.5+1
  flutter_icons: ^1.0.0+1
  flutter_launcher_icons: ^0.7.4
  url_launcher: ^5.4.2
  get: ^3.2.2

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  build_runner:
  json_serializable:
  flutter_test:
    sdk: flutter

当您使用它时，不妨看看您正在使用的所有其他软件包。将它们升级到较新的版本也可能会消除一些其他警告消息。
