Google Maps

In the event payload the return type of layer is `L.Layer? so it needs to be casted to the Layer-Type.

layer.on('pm:edit', (e) => {
  if(e.shape === 'Polygon'){
     (e.layer as Polygon).getLatLngs();
  }
});

I think following should work too: (But not tested)

layer.on('pm:edit', (e) => {
  if(e.layer instanceof L.Polygon){
     (e.layer as Polygon).getLatLngs();
  }

Suggestion

Add a section to the README about how to test this component.

Motivation

I've come across countless issues and questions in the gitter about how to test or mock this library. If anyone has done this before, please consider adding a testing guide to the README.

Thank you @JustFly1984 for your work !

Documentation is hard to read, could you just add a little description on each method ?

For example i don't really know what this method is usefull for :

The waypoint feature is awesome! Can you also expose the Duration and distance to each waypoint in the callback for onReady?
I believe Google's direction API response already contains that information.

Thanks for a great library!

The drawing layer can currently draw lines and polygons, but it would be useful to also draw circles (cf this tweet).

The GoogleMaps JavaScript API supports circles (see docs).

To implement this, I suggest looking at the current implementation for
