Developer Guide

Getting started

Create an instance of GoogleMap, configure it, add markers, polygons, etc:

GoogleMap gmaps = new GoogleMap(apiKey,null,null);
gmaps.setMapType(MapType.SATELLITE);
gmaps.setSizeFull();
gmaps.setCenter(new LatLon(0,0));
gmaps.addMarker("Center", new LatLon(0,0), true, "");
GoogleMapPolygon gmp = gmaps.addPolygon(Arrays.asList(new GoogleMapPoint(gmaps.getCenter()),
new GoogleMapPoint(gmaps.getCenter().getLat(),gmaps.getCenter().getLon()+1),
new GoogleMapPoint(gmaps.getCenter().getLat()+1,gmaps.getCenter().getLon())));
gmp.addClickListener(ev->Notification.show("polygon clicked"));

Special configuration when using Spring

By default, Vaadin Flow only includes com/vaadin/flow/component to be always scanned for UI components and views. For this reason, the add-on might need to be whitelisted in order to display correctly.

To do so, just add com.flowingcode to the vaadin.whitelisted-packages property in src/main/resources/application.properties, like:

vaadin.whitelisted-packages = com.vaadin,org.vaadin,dev.hilla,com.flowingcode

More information on Spring whitelisted configuration here.
