Stroke color different to fillcolor?

[coppertank]

I was wondering if it was possible to change the color of the polygons' border and make it different from the fill color. On light colored polygons, in fact, the border is not very visible.

I don't think this is supported by the upstream repo.

Same issue. So not possible to change the border color and width?

If not, a workaround is to addGlPolylines for this purpose.

Sorry @mtennekes I don't think leaflet.glify supports this. In mapview I simply render the borders on top of the polygons. See https://github.com/r-spatial/mapview/blob/master/R/sf.R#L317-L331
