Error: Gradle task assembleDebug failed with exit code 1

解决方案 #

1. 强制指定兼容的google_maps_flutter_android版本 #

在项目根目录的pubspec.yaml中添加dependency_overrides，锁定与你的google_maps_flutter版本匹配的Android端依赖版本：

dependency_overrides:
  google_maps_flutter_android: 2.15.0

执行命令更新依赖：

flutter pub get

2. 彻底清理缓存并重新构建 #

执行以下命令清除旧缓存和构建文件，再重新编译：

flutter clean
flutter pub cache clean
flutter pub get
flutter run

原理说明 #

你当前使用的google_maps_flutter 2.12.1与自动拉取的google_maps_flutter_android 2.16.0存在版本不兼容问题，后者的Gradle配置依赖更高版本的Flutter Gradle插件特性，而你的环境无法满足。通过锁定兼容的Android端依赖版本，可以解决该属性找不到的错误。
