[google_maps_flutter] Add methods to programmatically show/hide marker's infowindow

[giancarlopro]

Description

I needed to programmatically show marker's infowindow when a user tapped a polyline, so i've implemented those method and i'm currently using them and trying to maintain my repo current with this one.

I want a opinion on this implementation, because i don't think it's the optimal. I've tried to use a method channel for each Marker so i would be able to call marker.showInfoWindow(), but i can't create method channel's on the fly.

@SenseiBunny only one info window is displayed at a time as stated in the google documentation

I want to show multiple infoWindow in one map and in one time, how to do that?

in javascript I can do this :

function initMap() {
  const uluru = { lat: -25.363, lng: 131.044 };
  const map = new google.maps.Map(document.getElementById("map"), {
    zoom: 4,
    center: uluru,
  });
  
  const infowindowA = new google.maps.InfoWindow({
    content: "a",
  });
  
  const infowindowB = new google.maps.InfoWindow({
    content: "b",
  });
  
  
  const markerA = new google.maps.Marker({
    position: uluru,
    map,
    title: "A",
  });
  
  infowindowA.open({
  	anchor: markerA,
    map,
    shouldFocus: false,
  });
  
  
  const markerB = new google.maps.Marker({
    position: {lat: -22.925286, lng: 139.912982},
    map,
    title: "B",
  });
  
  infowindowB.open({
  	anchor: markerB,
    map,
    shouldFocus: false,
  });
}

I see in flutter to show the infoWindow we should do something like this :

GoogleMapsFlutterPlatform.instance.showMarkerInfoWindow(MarkerId("0"), mapId: controller.mapId);
// or
mapController.showMarkerInfoWindow(MarkerId("0"));

but if I do showMarkerInfoWindow twice It's still show just one infoWindow

for full code i want to this :

can I do something like this in flutter ?
