flutter-windows-ANGLE-OpenGL-ES

OpenGL ES hardware accelerated rendering on Flutter Windows Texture Widget using ANGLE.

Introduction

ANGLE (Almost Native Graphics Layer Engine) is used in this example, which translates these OpenGL ES calls to DirectX 11 (which Flutter Windows now supports) calls internally. The example uses the new Direct3D texture interop capability for Flutter Windows added by @jnschulze.

I compiled ANGLE for Windows on my machine & .DLLs / .LIBs are present in this repository, which are used by the application. The code in this repository is very straightforward & procedurally written without any boilerplate. I hope this serves as a great example.
