compositeFrame method

void compositeFrame ()

Uploads the composited layer tree to the engine.

Actually causes the output of the rendering pipeline to appear on screen.

Implementation

void compositeFrame() {
  Timeline.startSync('Compositing', arguments: timelineWhitelistArguments);
  try {
    final ui.SceneBuilder builder = ui.SceneBuilder();
    final ui.Scene scene = layer.buildScene(builder);
    if (automaticSystemUiAdjustment)
      _updateSystemChrome();
    _window.render(scene);
    scene.dispose();
    assert(() {
      if (debugRepaintRainbowEnabled || debugRepaintTextRainbowEnabled)
        debugCurrentRepaintColor = debugCurrentRepaintColor.withHue((debugCurrentRepaintColor.hue + 2.0) % 360.0);
      return true;
    }());
  } finally {
    Timeline.finishSync();
  }
}
