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

我正在尝试添加firebase依赖项.当我跑到跑步时,我得到了

您可以通过在项目的根目录上运行flutter packages pub deps来查找依赖于google_api_availability的程序包 – 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关系的方法 – 我想你只会在尝试构建它时找到它.

问题是您使用的是Android Gradle插件的3.3.1版本,该插件强制执行Kotlin 1.3.0或更高版本.与此同时,geolocator包依赖于google_api_availability,这似乎是使用Kotlin 1.2.71.目前没有使用Kotlin 1.3.0或更高版本的google_api_availability版本,因此您只有1个解决方案 – 将Android Gradle插件降级到版本3.2.1.
