将所有依赖项迁移到andriodx包将解决此问题。https://developer.android.com/jetpack/androidx/migrate

在这里，您的地理定位器最新使用的是androidx包，其中image_picker依赖使用android包。您需要将image_picker库更新到最新的https://pub.dev/packages/image_picker#-changelog-tab-

或

快速修复:将geo-locator降级到2.1.1以解决此问题。这不是一个最好的方法。

将所有依赖项升级到androidx compatable是您可以尝试的最佳方法。
