# Flutter GL
cross-platform call OpenGL API by Dart through dart:ffi. Provides OpenGL with Texture Widget on Flutter.
Support iOS, Android, Web, macOS, Windows
Linux TODO
Used by [three_dart](https://github.com/wasabia/three_dart)
## OpenGL API
the api is similar to WebGL
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 _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);
```
### why use NativeArray replace Dart List
Dart List convert to ffi pointer need memeory copy.
### Run Examples
Clone or download this repo
```
cd flutter_gl/flutter_gl/example
flutter run
```
## share opengl context with flutter_gl
### Android
when init the plugin, save share opengl context with ThreeEgl,
```
ThreeEgl.setContext("shareContext", shareEglEnv.eglContext);
```
so you can get it use ThreeEgl lib, then create yourself opengl context share with "shareContext"
```
shareContext = ThreeEgl.getContext("shareContext");
```
### iOS
for iOS the key is 3 ...
```
eAGLShareContext = ThreeEgl.getContext(key: 3);
```
### Web
no need ? just webgl
### Windows
not support get share context now
## Android
check the example project
copy the example/android/app/libs/aars/threeegl.aar
to your app android project same path
change minSdkVersion 24
