Flutter Web scrollwheel scrolls in slow steps on Firefox

Websites that are programmed with Flutter Web seem to have an issue when scrolling with the scrollwheel on the browser Firefox. Scrolling up and down with the scrollwheel does very small steps which gives a bad user experience. I tested this issue on alot of browser it only appears on Firefox. I also tested it on a bunch of different websites they all have the same problem. My website is https://alikortak.de if you want to try it yourself. Does anyone know how to fix this?
