运行合作方Flutter应用时遭遇flutter_local_notifications编译错误

运行合作方的Flutter应用时，flutter_local_notifications插件出现编译错误，具体错误信息如下：

C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\flutter_local_notifications-9.9.1\android\src\main\java\com\dexterous\flutterlocalnotifications\FlutterLocalNotificationsPlugin.java:1554: error: cannot find symbol

错误提示无法找到TIRAMISU和POST_NOTIFICATIONS符号，导致Gradle构建失败。

解决方案 #

这两个符号对应Android 13（API 33）的专属API，错误原因是Android构建环境未配置对应版本的编译SDK，可通过以下方式解决：

• 修改项目根目录下android/app/build.gradle文件，将compileSdkVersion和targetSdkVersion设置为33或更高版本：

  android {
    compileSdkVersion 33 // 或更高版本
    defaultConfig {
      targetSdkVersion 33 // 或更高版本
    }
  }
  

• 若使用Flutter 3.3及以上版本，同步更新android/build.gradle中的全局compileSdkVersion配置：

  buildscript {
    ext {
      compileSdkVersion = 33 // 或更高版本
      // 其他配置项保持不变
    }
  }
  

• 清理缓存并重新构建项目：
  执行以下命令：

  flutter clean
  flutter pub get
  flutter run
  

• 若无法升级SDK版本，可降级flutter_local_notifications插件至不依赖Android 13 API的版本（比如9.8.0），修改pubspec.yaml：

  dependencies:
    flutter_local_notifications: ^9.8.0
  

  执行flutter pub get重新拉取依赖即可。
