Summary
Hello all. I am using streamlit to build an app where I have a map, perform some spatial operations through a function, and then want to add these polygons/points/lines to my main map. I do these by adding them through the st.session_state bit. I want these shapes to have a particular style, and usually I’d do that by adding some info to the style function in the folium.GeoJson(…) code snippet. But they don’t seem to pick up the style.
Steps to reproduce
Code snippet:
if 'markers' not in st.session_state:
st.session_state["markers"] = []
fg = folium.FeatureGroup(name="Markers")
for marker in st.session_state["markers"]:
fg.add_child(marker)
m = create_map()
map = st_folium(m,
feature_group_to_add=fg,
width=1800,
height=500)
def make_polygons():
...
style1 = {'lineColor': '#000000'}
intersect = folium.GeoJson(intersecting_polygons, style_function= lambda x: style1)
st.session_state["markers"].append(intersect)
...
I expect it to pick up the style I have put in, but I get the default style.
