Display (walking) direction/route to a custom markers

Is your feature request related to a problem? Please describe.

I'm working on creating a map which has ability to show current location (already done using LocateControl plugin) and has custom markers. I would like to be able to show (walking) route to custom markers from my current location.

Going through bug reports, I found similar request in #484, but in my case it's definitely not solved as part of #669

Describe the solution you'd like

I would like to be able to use plugins such as:

• Leaflet Routing Machine
• Leaflet.Routing

as pointed on Leaflet Routing plugins list

Describe alternatives you've considered

From my current research alternative would be to use different library/backend with Google Maps, but unfortunately there isn't a lot of information on this either.

Additional context

Functionality I would like to achieve

Implementation
folium is maintained by volunteers. Can you help make a PR if we want to implement this feature?

If the time allows yes.

查看相关 issue #484 和 #669，然后调查请求中链接的 Leaflet Routing Machine 和 Leaflet.Routing 插件。定义如何将当前位置和自定义标记连接到步行路线，包括 folium 与 Leaflet 之间的集成边界；当用户可以显示到所选自定义标记的该路线时，此功能即完成。
