@override void bindTarget([ RenderTarget? renderTarget ])

Implementation

@override
void bindTarget([RenderTarget? renderTarget]) {
  if (renderTarget is _WGLRenderTarget) {
    _context.bindFramebuffer(
        web_gl.WebGL.FRAMEBUFFER, renderTarget._framebufferHandle);
    _context.viewport(
        0, 0, renderTarget.texture.width, renderTarget.texture.height);
  } else if (renderTarget == null) {
    _context.bindFramebuffer(web_gl.WebGL.FRAMEBUFFER, null);
    _context.viewport(0, 0, backWidth, backHeight);
  }

  super.bindTarget(renderTarget);
}
