颤振-升级破坏了我的应用程序

Question

我正在构建一个应用程序，它运行良好，直到我选择运行flutter-upgrade命令来升级我的安装。现在，我使用ListView的应用程序的一部分已经完全失效，在尝试访问应用程序中使用ListView的部分之后，应用程序的其余部分中断，小部件停止正常呈现。

在我升级我的颤振安装之前，一切都很好，我需要在下周之前完成这个应用程序。

这是日志：

我的颤振版本:颤振0.5.7

我目前在主频道，但应用程序仍然打破了最新的版本，从测试版渠道。

Answer 1

您可以随时通过在所需版本中克隆颤振存储库来降低颤振的级别。然后运行flutter doctor。

Answer 2

在前面的答案中添加，您可以使用dev分支而不是master。随着越来越多的人参与颤振，master可能变得不稳定。dev通常比主版晚一周，对于开发来说要稳定得多。
