Now the api is similar to WebGL

How to use #

Now this is only support draw to FBO. then share the FBO texture to Native side.

import #

import 'package:flutter_gl/flutter_gl.dart';

Usage #

int width = 200;
int height = 200;
num dpr = 1.0;

flutterGlPlugin = FlutterGlPlugin();

Map<String, dynamic> _options = {
    "width": width, 
    "height": height, 
    "dpr": dpr,
    "antialias": true,
    "alpha": false
};    
await flutterGlPlugin.initialize(options: _options);

// on web this need called after web canvas dom was added to document
await flutterGlPlugin.prepareContext();

// you can get gl by
gl = flutterGlPlugin.gl;

// then you can call OpenGL ES API by gl like
gl.clearColor(0.0, 0.0, 0.0, 1.0);
gl.clear(gl.COLOR_BUFFER_BIT);

// use this method to notify Flutter update Texture Widget
// sourceTextue is a texture which bind to FBO framebuffer
flutterGlPlugin.updateTexture(sourceTexture);
