My Android project uses an opengl lib written in c++, I'm using an Android SurfaceView subclass, now I would like to recreate my app starting with a flutter project. Some of you know how can I achieve it? Thanks.

You may find this article helpful which shows how to use Flutters TextureRegistry to obtain SurfaceTextures that you can then render into.

But given you say you are using a SurfaceView at the moment, you'll need to find some way to wire up your c++ lib differently for Flutter.

In my use case I needed to do what you are trying to do, use a c++ library rather than Java GLES code as in the article I linked. So what I did was use EGL call in Java side to create an EGLSurface

mEGL.eglCreateWindowSurface(mEGLDisplay, mEGLConfig, texture, null)

which I could then make use of in C++ code that ran on the same thread, so I had access to the EGLSurface to render it into.

  • Hi, nice example I am doing a 3D app with flutter using OpenglES but I get memory leaks, can you explain how I can do it with C++. Do you have any github repository so I will find an example. Thank you. – George C. Feb 05 '22 at 12:12
  • Sorry @GeorgeC. I don't have any publicly available sample code for this. – Maks Feb 17 '22 at 06:12
  • Don't warry @Maks I understand. Have a nice day :) – George C. Feb 18 '22 at 10:32
  • hi @GeorgeC. did you able to find solution? – Kalana Perera May 02 '22 at 15:57
  • hi @KalanaPerera my work so far you can find it in pub.dev as "flgl" you can analyze the code, but I have stop the development. Maybe I will focus again in the future. Good luck – George C. May 05 '22 at 08:54
