Error when trying to create an "empty" sticker (only with package name)

[dhersz]

I'm trying to come up with a minimalist hex sticker, but I'm having some problems when creating an empty sticker (i.e. that contains just the package name). The first time I try to create it using sticker() it works fine, but any subsequent attempts raise an error. See the reprex below:

library(hexSticker)

a <- sticker(
  subplot = ~ plot.new(),
  package = "test",
  filename = tempfile(fileext = ".png")
)

class(a)
#> [1] "sticker" "gg"      "ggplot"

a <- sticker(
  subplot = ~ plot.new(),
  package = "test",
  filename = tempfile(fileext = ".png")
)
#> Warning in editThisGrob(grob, specs): slot 'vp' not found
#> Warning in editThisGrob(grob, specs): slot 'name' not found
#> Error in UseMethod("validGrob"): no applicable method for 'validGrob' applied to an object of class "NULL"

Can confirm. Even the demo example fails with that same error when ran a second time in a fresh R session.

I've noticed that loading hexSticker loads a bunch of other packages that I'm not sure should be there. This is part of my sessionInfo() right after loading the package:

Maaaybe that generates some conflict that triggers the reported issues?

It seems to be working with ggplot2::ggplot() + ggplot2::theme_void().
