来自flutter内部的dart-sdk问题

Question

我运行flutter升级，得到以下消息

C:\Users\lenovo\IdeaProjects\simple>flutter upgrade
Flutter is already up to date on channel stable
Flutter 2.5.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 18116933e7 (3 weeks ago) • 2021-10-15 10:46:35 -0700
Engine • revision d3ea636dc5
Tools • Dart 2.14.4

但是当我尝试升级包时，包括riverpod，它今天已经稳定发布了

我收到了以下消息

The current Dart SDK version is 2.13.4.

    Because simple depends on flutter_riverpod >=1.0.0 which requires SDK version >=2.14.0 <3.0.0, version solving failed.
    pub get failed (1; Because simple depends on flutter_riverpod >=1.0.0 which requires SDK version >=2.14.0 <3.0.0, version solving failed.)

在当前使用的编辑器设置中检查dart sdk时，dart sdk的版本为2.13.4

有人知道如何解决这个问题吗?？

尝试删除版本，只保留pubspec.yaml中的依赖项名称。然后运行flutter pub get。它将自动下载所有兼容版本。
