How would I add a custom handler for tap events for Google Maps Marker (google_maps_flutter)? I can only see consumeTapEvents which doesn't actually take in any functions but only bool. I've thought of using GestureDetector but doesn't seem quite right.
What is the standard way of handling events on Google Map's Markers? I'm trying to navigate to a new page upon click.
Thanks
This is the simplest I could reduce it to:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<title>Google Maps Multiple Markers</title>
<script src="http://maps.google.com/maps/api/js?key=YOUR_API_KEY"
type="text/javascript"></script>
</head>
<body>
<div id="map" style="width: 500px; height: 400px;"></div>
<script type="text/javascript">
var locations = [
['Bondi Beach', -33.890542, 151.274856, 4],
['Coogee Beach', -33.923036, 151.259052, 5],
['Cronulla Beach', -34.028249, 151.157507, 3],
['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
['Maroubra Beach', -33.950198, 151.259302, 1]
];
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}
</script>

SCREENSHOT
There is some closure magic happening when passing the callback argument to the addListener method. This can be quite a tricky topic if you are not familiar with how closures work. I would suggest checking out the following Mozilla article for a brief introduction if it is the case:
http://infocenter.arm.com/help/topic/com.arm.doc.prd29-genc-009492c/index.html is a pretty good introductory document that gives an overview of something a little bit too complex to be satisfactorily explained by typing into a text box. But I'll try to answer your direct questions below.

With the release of version ^0.3.0+1 a new Marker API was introduced which handles markers as widgets (including an onTap() method). This way a Google Map has a
markers:option which admits a list of Marker objects. Each of the elements can be defined like this:Much easier than the former controller approach!
