flutter attach - Oops；flutter意外退出

Question

从android studio终端运行flutter attach不起作用。显示错误Oops；flutter意外退出。

终端输出：

flutter attach
Checking for advertised Dart observatories...

Oops; flutter has exited unexpectedly.
Sending crash report to Google.
Crash report sent (report ID: 50ca8df4de508ad3)

Crash report written to /Users/johnnykuttymathew/Documents/Work/Code/<project>/flutter_04.log;

如何避免这种情况？所有的项目都会发生这种情况。甚至是以前创建的项目。

要安装Flutter和Dart插件：

->启动Android Studio。

->打开插件首选项( macOS上的首选项>插件，Windows和Linux上的文件>设置>插件)。

->选择Browse repositories，选择Flutter插件并单击Install。

->当系统提示安装Dart插件时，单击是。

->出现提示时，单击重新启动。

Answer 2

a)请仔细检查所有依赖组件是否正确安装。b)您还需要检查是否有多个android-sdk没有安装，如果是，卸载两个sdk可能会产生问题。c)如果设置为Android_Home，则重置Android-sdk路径(许多开发人员执行了此操作并将其修复) d)有时flutters依赖项会遇到权限问题，如果您是在Mac上，可以通过在终端上运行sudo su或在Windows上运行命令提示符来解决。

Answer 3

尝试升级Flutter / Dart插件，并使用flutter channel stable将通道更改为稳定。
