颤动| Android Gradle 插件仅支持 Kotlin Gradle 插件版本 1.3.0 及更高版本

可以找到依赖哪个包google_api_availability通过跑步flutter packages pub deps在项目的根目录上 - 这将在树视图中列出项目的所有直接和传递依赖项。

我找不到显示包的插件依赖项的方法 - 我猜你只有在尝试构建它时才会发现。

问题是你使用的版本3.3.1Android Gradle 插件的一部分，它强制执行 Kotlin1.3.0或以上。与此同时，geolocator包取决于google_api_availability，似乎正在使用 Kotlin1.2.71。目前还没有版本google_api_availability使用 Kotlin1.3.0或以上，所以你只有 1 个解决方案 - 将 Android Gradle 插件降级到版本3.2.1.
