Project mention: Seeking Guidance and Implementation Tips for Vanta.js-like Effects in Flutter | /r/flutterhelp | 2023-06-01

Looking that the source code, it seems that these are implemented using shaders. Those are a new thing in Flutter, so I'd try to go that road. You probably need a CustomPaint with a CustomPainter, painting a Rect with a Paint using that Shader, feeding it all input parameters. I've absolutely no experience with shaders in Flutter, but that's what I'd try for something simple like the fog. For the birds, you'd probably need to implement a lot of 3D geometry yourself.

A fast, flexible, and small SEO-friendly lazy loader.

Project mention: Tips For Building Faster Websites with Efficient CSS Optimisation | dev.to | 2023-08-14

Developers also employ alternative methods for lazy loadings, such as the scroll event listener, besides the Intersection Observer API and the loading property. Unlike the Intersection Observer API, which only monitors the elements targeted for lazy loading, developers attach a scroll event listener to every element on the page. Once the element marked for lazy loading is within the visibility range of the user, a function is invoked to switch the image or video URL with the attribute previously holding it, just like with the Intersection Observer API. This approach is costly for a web project. As the developer seeks to optimise page load by integrating lazy loading to some elements on the webpage, the developer slows down the page's performance due to multiple firing of an event as the function meets each element. Moreover, packages for JavaScript that deal with lazy loading exist. For instance, the LazyLoad library uses the Intersection Observer API, a lightweight JavaScript library. It supports many lazy loading features, such as preloading, responsive image loading, and custom loading animations. Additional lazyloading libraries include Yall.js, Lozad.js, LazyLoad XT for jQuery, and many more.
