最近升级时出现颤振错误

Question

我遇到了一些奇怪的颤振错误，所以我用谷歌搜索它们并被告知升级颤振似乎没有帮助。我没有碰过这些文件中的任何一个，这是一个错误吗？前一段时间它工作得很好。 我尝试过flutter clean、flutter upgrade、flutter doctor和flutter pub cache repair 这里是扑医生：

Answer 1

问题似乎是由flushbar_route插件引起的。

尝试编辑 flushbar-1.9.1/lib/flushbar_route.dart，它位于

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

Line 273
void install() {

And line 281
super.install();

或者第二个修复方法是将下面的行放在您的 pubspec.yaml 文件中

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

Answer 2

在我的情况下，对 pubspec.yaml 的建议编辑导致与其中一个依赖项发生版本冲突。 我刚刚在 pubspec.yaml 的依赖项部分中添加了对稳定旧版本flushbar 的引用

    dependencies:
        flushbar: 1.9.1

Answer 3

似乎（在极少数情况下）不稳定的插件或颤振。

我建议你切换到稳定的颤振频道（如果是开发版或测试版）

flutter channel stable

并应用颤振升级

flutter upgrade

即使您正在编写升级，也可以随时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。
