Question

当我将 pubnub: ^1.4.4 添加到 pubspec.yaml 时出现此异常

<块引用>

因为 pubnub >=1.0.2 <3.2.0 依赖于 dio ^3.0.0 和 talad_flutter 取决于 dio ^4.0.0，禁止 pubnub >=1.0.2 <3.2.0。所以，因为 talad_flutter 依赖 pubnub ^1.4.4，版本解析失败。

我已经尝试减少每个库的版本，但仍然没有运气。

这是我的完整 pubspec.yaml

根据 PubNub 工程

这是一个非常过时的 pubnub 软件包版本。目前我们在 3.x 上，即将发布 4.x
通常，您始终可以使用 Dart 使用依赖项覆盖来解决此类问题

Answer 2

如果您更新了最新版本。可能是错误版本。你可以使用

  provider: 
  http: 
  flutter_staggered_grid_view: 
  carousel_slider:
  countdown_flutter: 
  intl: 
  percent_indicator: 
  custom_refresh_indicator: 
  material_design_icons_flutter:
  flutter_spinkit: 
  image_picker: 
  firebase_ml_vision:
  firebase_core: 
  cached_network_image:
  font_awesome_flutter: 
  cloud_firestore: 
  url_launcher: 
  rflutter_alert:
  shared_preferences:
  smooth_star_rating:
  share:
  flutter_html: 
  dio: 
  flutter_tags: 
  package_info:
  smart_select: 
  google_maps_flutter: 
  geolocator: 
  timeago:
  firebase_storage: 
  firebase_messaging: 
  fl_chart: 
  webview_flutter: 
  pubnub:

然后扑到酒吧。它对你有用。
