flutter - Flutter Pubnub 版本解决失败

问题描述

当我添加pubnub: ^1.4.4到 pubspec.yaml时出现此异常

因为 pubnub >=1.0.2 <3.2.0 取决于 dio ^3.0.0 而 talad_flutter 取决于 dio ^4.0.0，所以 pubnub >=1.0.2 <3.2.0 是被禁止的。所以，因为 talad_flutter 依赖于 pubnub ^1.4.4，版本求解失败。

我试图减少每个库的版本，但仍然不走运。

这是我完整的 pubspec.yaml

解决方案

根据 PubNub 工程

  • 这是pubnub包的一个非常过时的版本。目前我们在 3.x 和即将发布 4.x
  • 一般来说，你总是可以使用依赖覆盖来解决 Dart 的此类问题
