crash - 为什么升级到 Flutter v0.7.3 beta 会阻止我的应用程序运行？

Question

我已将 Flutter 版本从 0.5.1 beta 升级到 0.7.3 beta，因为少数插件无法正常工作，建议我升级到最新版本，包括插件和 Flutter 本身。但是，这完全破坏了应用程序，因为它甚至无法启动。下面是 Android Studio 运行控制台输出

以下是 flutter 医生的输出

我确信 allElements() 不是飞镖或 flutter 代码。它是 Java 内部代码，意味着插件或 Flutter 本身已损坏。

我感到非常尴尬，因为这是我自己的行为导致了这个问题。我终于通过转到Android list 文件来修复它并删除了有问题的

tools:replace="android:label"

出于某种我不知道的原因，我将其放入标签中。那我就..

flutter clean

然后运行应用程序工作!瞧!
