Leaflet 1.9.1 does not include L.GeometryUtil

[Concequence]

Recently updated to Leaflet 1.9.1 and the L object does not have GeometryUtil, which this package relies on to work.
I could not find a way to get this working without just downgrading Leaflet.

Also do you plan to update this for React 17/18 ?

Hmmmm, I have not tried this with 1.9 yet, but I imagine the removal of the L global in leaflet 1.9 is going to cause alot of problems with tons of plugins in the leaflet ecosystem. The 1.9 release notes do mention

we will provide a shim that can be imported manually that will restore this functionality

Though I have no idea when that will happen. Ultimately this problem is upstream, with leaflet-geometryutil and leaflet itself. But, it does bother me, so there's a pretty simple shim you can do yourself to get this working with leaflet ^1.9

Install leaflet-geometryutil as a dependency of your project

npm i leaflet-geometryutil

When you import 'leaflet-arrowheads', attach GeometryUtil to L yourself:

import L from "leaflet";
import "leaflet-arrowheads";
import GeometryUtil from "leaflet-geometryutil";

L.GeometryUtil = GeometryUtil;

Seems to work fine

I think they've reversed the change in 1.9.2
