错误截图 #

解决方案 #

从错误截图来看，问题是Google Play服务相关依赖版本冲突导致重复类，具体是com.google.android.gms.common.api.zza等类在多个jar包中重复出现。可以按以下步骤解决：

• 统一Play服务依赖版本：在项目的android/build.gradle文件中，找到allprojects节点，添加版本强制策略，确保所有依赖使用相同版本的Play服务库：

allprojects {
    repositories {
        google()
        mavenCentral()
    }
    configurations.all {
        resolutionStrategy {
            force 'com.google.android.gms:play-services-base:18.1.0'
            force 'com.google.android.gms:play-services-basement:18.1.0'
            // 若还有其他重复类，可根据错误提示添加对应的库版本强制
        }
    }
}

• 清理缓存并重建：

  1. 执行命令清理项目缓存：flutter clean
  2. 重新获取依赖：flutter pub get
  3. 尝试重新构建Release APK：flutter build apk --release

• 查看详细冲突报告：如果问题仍存在，可查看android/app/build/outputs/mapping/release/duplicate_classes.txt文件，里面会列出所有重复的类和对应的依赖库，针对性调整版本或排除冲突依赖。

• 调整pubspec依赖：检查pubspec.yaml中依赖的版本，比如geolocator、firebase系列、google_maps_flutter这些依赖Play服务的库，尝试升级到兼容的版本，或者在dependency_overrides中强制统一相关依赖的版本。
