Flutter plugin for launching maps

Map Launcher

Map Launcher is a flutter plugin to find available maps installed on a device and launch them with a marker or show directions.

Marker	Navigation

Currently supported maps:
Google Maps
Apple Maps (iOS only)
Google Maps GO (Android only)
Baidu Maps
Amap (Gaode Maps)
Waze
Yandex Maps
Yandex Navigator
Citymapper
Maps.me
OsmAnd
2GIS
Tencent (QQ Maps)

Migrating to v1

Breaking change: map_launcher does not depend on flutter_svg anymore which means you will have to add flutter_svg in your project if you want to use images.

This should allow you to use any version of flutter_svg and it also fixes bunch of issues related to that like #45, #40, etc

The icon property from AvailableMap now returns String instead of ImageProvider so to get it working all you have to do is to go from

Image(
  image: map.icon,
)

to

import 'package:flutter_svg/flutter_svg.dart';

SvgPicture.asset(
  map.icon,
)

Get started

Add dependency

dependencies:
  map_launcher: ^1.1.3
  flutter_svg: # only if you want to use icons as they are svgs

For iOS add url schemes in Info.plist file

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>comgooglemaps</string>
    <string>baidumap</string>
    <string>iosamap</string>
    <string>waze</string>
    <string>yandexmaps</string>
    <string>yandexnavi</string>
    <string>citymapper</string>
    <string>mapswithme</string>
    <string>osmandmaps</string>
    <string>dgis</string>
    <string>qqmap</string>
</array>

Usage

Get list of installed maps and launch first

import 'package:map_launcher/map_launcher.dart';

final availableMaps = await MapLauncher.installedMaps;
print(availableMaps); // [AvailableMap { mapName: Google Maps, mapType: google }, ...]

await availableMaps.first.showMarker(
  coords: Coords(37.759392, -122.5107336),
  title: "Ocean Beach",
);

Check if map is installed and launch it

import 'package:map_launcher/map_launcher.dart';

if (await MapLauncher.isMapAvailable(MapType.google)) {
  await MapLauncher.showMarker(
    mapType: MapType.google,
    coords: coords,
    title: title,
    description: description,
  );
}

Example

Using with bottom sheet

import 'package:flutter/material.dart';
import 'package:map_launcher/map_launcher.dart';
import 'package:flutter_svg/flutter_svg.dart';

void main() => runApp(MapLauncherDemo());

class MapLauncherDemo extends StatelessWidget {
  openMapsSheet(context) async {
    try {
      final coords = Coords(37.759392, -122.5107336);
      final title = "Ocean Beach";
      final availableMaps = await MapLauncher.installedMaps;

      showModalBottomSheet(
        context: context,
        builder: (BuildContext context) {
          return SafeArea(
            child: SingleChildScrollView(
              child: Container(
                child: Wrap(
                  children: <Widget>[
                    for (var map in availableMaps)
                      ListTile(
                        onTap: () => map.showMarker(
                          coords: coords,
                          title: title,
                        ),
                        title: Text(map.mapName),
                        leading: SvgPicture.asset(
                          map.icon,
                          height: 30.0,
                          width: 30.0,
                        ),
                      ),
                  ],
                ),
              ),
            ),
          );
        },
      );
    } catch (e) {
      print(e);
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Map Launcher Demo'),
        ),
        body: Center(child: Builder(
          builder: (context) {
            return MaterialButton(
              onPressed: () => openMapsSheet(context),
              child: Text('Show Maps'),
            );
          },
        )),
      ),
    );
  }
}

Known issues

• Google Maps for Android have a bug that setting label for a marker doesn't work. See more on Google Issue Tracker

• On iOS it's possible to "delete" Apple Maps which actually just removes it from homescreen and does not actually delete it. Because of that Apple Maps will always show up as available on iOS. You can read more about it here
