[!] CocoaPods could not find compatible versions for pod "BaiduMapKit/Base": In Podfile: flutter_baidu_mapapi_base (from `.symlinks/plugins/flutter_baidu_mapapi_base/ios`) was resolved to 3.3.1, which depends on BaiduMapKit/Utils (= 6.5.5) was resolved to 6.5.5, which depends on BaiduMapKit/Base (= 6.5.5) flutter_baidu_mapapi_map (from `.symlinks/plugins/flutter_baidu_mapapi_map/ios`) was resolved to 3.1.0, which depends on BaiduMapKit/Map (= 6.5.1) was resolved to 6.5.1, which depends on BaiduMapKit/Base (= 6.5.1)

这个错误提示说明了 `flutter_baidu_mapapi_base` 依赖于 `BaiduMapKit/Base` 版本为 6.5.5，而 `flutter_baidu_mapapi_map` 依赖于 `BaiduMapKit/Base` 版本为 6.5.1，两者版本不兼容导致冲突。

可以尝试更新 `flutter_baidu_mapapi_base` 或 `flutter_baidu_mapapi_map` 的版本，使其依赖的 `BaiduMapKit/Base` 版本保持一致，或者升级 `BaiduMapKit/Base` 到一个兼容两者的版本。

具体操作步骤：

1. 打开项目目录下的 `Podfile` 文件。
2. 在文件中找到 `flutter_baidu_mapapi_base` 和 `flutter_baidu_mapapi_map` 两个依赖项，并指定它们的版本号，使它们依赖的 `BaiduMapKit/Base` 版本保持一致。例如：

   pod 'flutter_baidu_mapapi_base', '3.3.1'
   pod 'flutter_baidu_mapapi_map', '3.1.0'

3. 保存 `Podfile` 文件，并在终端中执行 `pod install` 命令，让 CocoaPods 安装指定版本的依赖库。

如果以上方法无法解决问题，可以尝试升级 `BaiduMapKit/Base` 到一个兼容两者的版本，或者联系 `flutter_baidu_mapapi_base` 和 `flutter_baidu_mapapi_map` 的开发者寻求帮助。
