已尝试操作 #

• 执行flutter clean
• 执行.\gradlew clean build

解决措施 #

1. 对齐Gradle插件与Gradle版本兼容性 #

shared_preferences_android-2.1.0依赖的Android Gradle插件版本为7.2.2，而项目根配置的是7.2.0，同时Gradle版本7.5与7.2.0插件不兼容（官方兼容表中7.2.x插件对应Gradle 7.3）。可二选一调整：

• 调整项目插件版本：修改项目/android/build.gradle中的插件版本为7.2.2，与依赖库一致：

  dependencies {
      classpath 'com.android.tools.build:gradle:7.2.2'
      // 其余依赖保持不变
  }
  

• 调整Gradle版本：修改gradle-wrapper.properties中的Gradle版本为7.3：

  distributionUrl=https\://services.gradle.org/distributions/gradle-7.3-bin.zip
  

2. 彻底清除Gradle缓存 #

仅执行flutter clean和gradlew clean不够，需手动删除全局Gradle缓存目录：

• 删除C:\Users\rakhtama\.gradle\caches
• 重新执行flutter pub get和flutter run

3. 升级shared_preferences版本 #

若上述方案无效，升级到最新稳定版可修复兼容性问题：

• 修改pubspec.yaml中的依赖：

  shared_preferences: ^2.2.2 # 替换为最新稳定版
  

• 执行flutter pub upgrade
