for the texture part, linux didn't handle GLES extension OES_EGL_image_external, which is an extension of GLES. so things are different.

I don't quite understand what you mean. I told nothing about linux in the above comment. You may build the current flutter-2.0.1-tizen branch yourself and understand what the current problem is.

sorry, it's windows, not linux. I mean windows/linux like desktop use GL instead of GLES.
I think, windows texture is applied in scenario like webrtc, the texture data is from CPU, but in our case, the data we use is from GPU, we can't do CPU-GPU copy, so a handle is tranferred instead of a buffer in ExternalTextureGL::CopyPixelBuffer

For the texture part.
The common part is get data from pixel buffer(CPU->GPU)
Our implementation is get data from tbm surface(GPU->GPU)
so we need provider two sets of interface:
1.we need modify tbm interface name to make it more clearly.
2.we should implement pixel buffer part.

2.0.1 has landed. Actually a new hotfix (2.0.2) was released in the upstream but will not update to it since there's no or little difference.
