使用 Getx widget-Flutter 运行时显示错误

如何解决使用 Getx widget-Flutter 运行时显示错误

此错误仅在我使用 get package 时发生。为了解决这个问题,我从 .pub-cache/hosted/pub.dartlang.org 目标中删除了 get 文件夹,然后再次导入它,但没有任何反应。

Launching lib\main.dart on sdk gphone x86 arm in debug mode...
Running Gradle task 'assembleDebug'...

我使用了很多其他的包,但只有在使用 get 包时才会出现错误。

解决方法

打开你的安卓工作室终端

1 - 清理你的项目

flutter clean 

2 - 将颤振通道更改为稳定

Flutter channels:
  master
  dev
  beta
* stable

确保您使用的是稳定频道

3 - 现在你需要升级 flutter upgrade(在终端上)

flutter upgrade 

输出

Flutter is already up to date on channel stable
Flutter 2.0.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision c5a4b4029c (2 days ago) • 2021-03-04 09:47:48 -0800
Engine • revision 40441def69
Tools • Dart 2.12.0

4 - 再次清洁

flutter clean 

如果你使用 flutter 2 那么一切都很好:)
