This event is fired when the map is created using the map.getMap() method.
<div id="map_canvas"></div>var div = document.getElementById("map_canvas");
var map = plugin.google.maps.Map.getMap(div);
// At this time, the map instance is not ready yet.
// So don't do anything.
//
// map.setCameraZoom(3); <--- This is bad timing.
// After the MAP_READY event, you can modify the map.
map.one(plugin.google.maps.event.MAP_READY, function() {
});
