pose detection modification

Hi,

First of all, thank you for spending time working up and publish this. This is very kind of you. I have tried this and it works great. However, I would like to create another version for pose detection, I have re-compile the aar, copy the tflite and binary graph as you suggest. I also modify the NativeView to set the graph name and output, but when I run it, I got segfault like following:

E/DecorView(25629): mWindow.mActivityCurrentConfig is null

Do you have any idea on what is it about and how to fix it? Actually, I can make the sample work with AAR and Java but never try with flutter before.

Thanks
