Flutter如何解决AndroidX不兼容问题

Question

当我在 Flutter 项目中安装 geolocator 包时，我收到第一张图片中的错误。当我将 minSdkVerison 值设置为 21 时，错误发生了变化，我得到了第二个错误。但我猜第二个错误与 geolocator 无关，因为如果我卸载 geolocator 包，当 minSdkVersion 为 21 时我会收到该错误。我尝试 flutter clean 并将 multiDexEnabled 设置为 true 但它没有修复。我该如何解决这个问题？

您使用的是哪个版本的 Firestore？ 将 SDK 设置为 21 并保持 multidex 不变，版本 21 处理它。根据您的无效安全状态使用最新版本的地理定位器和 Firestore。
