Flutter Firebase 版本解决失败 - 专家请指定版本

Question

因为 cloud_firestore_web 0.2.1+2 依赖于 http_parser ^3.1.3 并且没有 cloud_firestore_web 的版本匹配 >0.2.1+2 =0.13.0 依赖于 http_parser ^4.0.0 而 cloud_firestore 0.14.4 依赖于 cloud_firestore_web ^0.2.1+2，所以 http >=0.13.0 与 cloud_firestore 0.14.4 不兼容。 因此，由于市场同时依赖于 cloud_firestore 0.14.4 和 http 0.13.2，版本求解失败。 pub get failed (1; 因此，由于市场同时依赖于 cloud_firestore 0.14.4 和 http 0.13.2，版本解析失败。)

我是flutter新手，请帮我解决这个问题

尝试运行“Flutter pub upgrade”。您可以在 Android Studio 的终端窗口中键入命令。或者，如果您打开 pubspec.yaml 文件，您将在顶部看到 Pub upgrade 命令，在 Pub get 旁边。运行该命令将获得最新版本的库，并且可能会解决问题。

如果这不起作用，请尝试运行“Flutter pub outdated”和“Flutter pub upgrade --major-versions”。

编辑：

这将返回 'Pub get' 而不会出错：

  cupertino_icons: ^1.0.3
  google_maps_flutter: ^2.0.6
  #google_map_location_picker: 4.1.7
  mvc_pattern: ^7.4.0
  global_configuration: ^2.0.0-nullsafety.1
  html: ^0.15.0
  shared_preferences: ^2.0.6
  flutter_html: ^2.1.0
  flutter_svg: ^0.22.0
  location: ^4.3.0
  webview_flutter: ^2.0.9
  url_launcher: ^6.0.9
  firebase_messaging: ^10.0.3
  cached_network_image: 2.5.0
  fluttertoast: ^8.0.7
  flutter_staggered_grid_view: ^0.4.0
  intl_utils: 2.3.0
  carousel_slider: ^4.0.0
  cloud_firestore: ^2.3.0
  firebase_auth: ^2.0.0
  firebase_core: 1.3.0

我不得不注释掉 google_map_location_picker，因为那是一个过时的库。该库的作者似乎已经放弃了该项目。 google_maps_place_picker 可能是一个合适的选择。
