[BUG] Unable to change the basemap_style about lonboard HOT 2 CLOSED

The string is not the name of the basemap style; it's the URL where the style is located. You can use CartoBasemap as a helper to not need to recall the URL.

from lonboard.basemap import CartoBasemap
from lonboard import Map

Map(layers=[], basemap_style=CartoBasemap.DarkMatter)

if you print the value of that enum variant, you can see the URL it points to:

print(CartoBasemap.DarkMatter.value)
# https://basemaps.cartocdn.com/gl/dark-matter-gl-style/style.json

So it would also work if you passed that str into the Map directly

from lonboard.basemap import CartoBasemap
from lonboard import Map

Map(
    layers=[],
    basemap_style="https://basemaps.cartocdn.com/gl/dark-matter-gl-style/style.json",
)

from lonboard.

We can probably make a better error message by asserting that the str input to basemap_style is a URL of some kind

from lonboard.
