Upgrade Info from Guide:

Sometimes your block should also register some css or js files, therfore you can access the global {{\luya\web\View}} Object inside of your PHP view template. Its like registering other assets, by the difference that you are accessing the global scope view instead of the view on $this. An example of how to integrate an asset file:

Assuming the blow code is the PHP View of your Block:

MyBlockAsset::register($this->appView);

Now your [[app-assets.md]] is registered in the appliation view object.
