Question

我遇到了一些奇怪的抖动错误，因此我用谷歌搜索了它们，并被告知要升级抖动，这似乎没有帮助。我没有触摸任何这些文件，这是一个错误吗？之前工作还不错。我已经尝试过清理干净，升级Flutter，清理Doctor和修复pub pub缓存这是扑扑的医生：

Answer 1

在我的情况下，对pubspec.yaml的建议编辑导致其中一个依赖项发生版本冲突。我只是在pubspec.yaml的“依赖项”部分中添加了对flushbar稳定旧版的引用

    dependencies:
        flushbar: 1.9.1

Answer 2

问题似乎是由flushbar_route插件引起的。

尝试编辑位于

的 flushbar-1.9.1 / lib / flushbar_route.dart

“％YOURFLUTTERPATH％.pub-cache \ hosted \ pub.dartlang.org \ flushbar-1.9.1 \ lib \ flushbar_route.dart”

Line 273
void install() {

And line 281
super.install();

或者第二个解决方法是将下面的行放在pubspec.yaml文件中

flushbar:
    git:
      url: git://github.com/valterh4ck3r/flushbar
      ref: master

Answer 3

（在极少数情况下）似乎是不稳定的插件或抖动。

我建议您切换到稳定的抖动通道（如果在开发人员或Beta中）

flutter channel stable

并应用flutter升级

flutter upgrade

即使您正在编写升级，也始终可以获得稳定的最新版本。这解决了我的情况。希望这会有所帮助。
