Google Map Navigation in Flutter

问题

I'm new to flutter.

I found Flutter doesn't support inline map, only a static map view.

I wanted to build an app which I need to show the driving directions on the map.

Is it possible to create the same in flutter?

you can use android_intent library in flutter for starting googlemaps and get diection in android.

library : https://pub.dartlang.org/packages/android_intent

and in ios you can use both google api like comgooglemaps or google map url {i choose this one} and maps.apple.com.

String origin="somestartLocationStringAddress or lat,long";  // lat,long like 123.34,68.56
String destination="someEndLocationStringAddress or lat,long";
if (new LocalPlatform().isAndroid) {
      final AndroidIntent intent = new AndroidIntent(
          action: 'action_view',
          data: Uri.encodeFull(
              "https://www.google.com/maps/dir/?api=1&origin=" +
                  origin + "&destination=" + destination + "&travelmode=driving&dir_action=navigate"),
          package: 'com.google.android.apps.maps');
      intent.launch();
    }
    else {
        String url = "https://www.google.com/maps/dir/?api=1&origin=" + origin + "&destination=" + destination + "&travelmode=driving&dir_action=navigate";
        if (await canLaunch(url)) {
              await launch(url);
       } else {
            throw 'Could not launch $url';
       }
    }

i hope it helps.

At the time of writing this answer, the work on inline maps is still in progress. But since the guys at flutter have given others the ability to develop plugins, there are some alternatives.
