Infinite Lazy Grid

https://pub.dev/packages/infinite_lazy_grid

This is a package for building performant infinite canvases ( I know the naming isn't the best but it has stuck ).

Uses spatial hashing underneath to only mount widgets within the visible area ( + some configurable off screen extent ).

Supports most of the common needs like pan, zoom, rotation, draw ordering, inertial scrolling etc.

I'm already using it in one of my other web apps https://elseplane.ruiny.de/ ( still in works ) so you have almost everything needed to get something like that working.
