本地安装多个Flutter SDK版本埋的一个坑

将Flutter module 嵌入到原生做混合开发时，遇到一个奇怪现象，模拟器能正常跑起来，但一运行到真机，进入到flutter模块就直接白屏。

通过查看控制台打印的log，发现了如下错误信息：

   [VERBOSE-2:shell.cc(103)] Dart Error: Can't load Kernel binary: Invalid SDK hash. 
   [VERBOSE-2:dart_isolate.cc(171)] Could not prepare isolate.
   [VERBOSE-2:runtime_controller.cc(415)] Could not create root isolate.
   [VERBOSE-2:shell.cc(588)] Could not launch engine with configuration. 

搜索最后一条信息 Could not launch engine with configuration 时看到网上给出了对应的答案：

尝试了对应的方案，无果。

接着搜索第一条信息Can't load Kernel binary: Invalid SDK hash，总算是找到了对我有用的答案：

问题的根源就是在于我本地存在多个Flutter SDK版本，当时同一个项目需要切换不同版本时，进行对应的套件安装估计出了问题，所以就导致我在运行项目时无法正常显示。
