Quick Start

dependencies:
  map_launcher: ^5.0.0
  flutter_svg: # optional — only needed for map icons

import 'package:map_launcher/map_launcher.dart';

// Show a marker (opens the best available map)
await MapLauncher.marker(.coords(59.33, 18.07, title: 'Gamla Stan')).show();

// Show directions
await MapLauncher.directions(.coords(59.33, 18.07), mode: .walking).show();

// Search
await MapLauncher.marker(.search('Fika near Södermalm')).show();

// Specific map
await MapLauncher.marker(.coords(59.33, 18.07)).show(map: .google);

// Discover available maps
final maps = await MapLauncher.marker(.coords(59.33, 18.07)).getSupportedMaps();

Setup

iOS — Add URL schemes to Info.plist

Required for detecting installed native apps:

<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>

Android — No setup needed

Web / Desktop — No setup needed

API

Markers

// By coordinates
await MapLauncher.marker(.coords(59.33, 18.07, title: 'Gamla Stan')).show();

// With zoom level
await MapLauncher.marker(.coords(59.33, 18.07), zoom: 14).show();

// By search query (Google & Apple Maps)
await MapLauncher.marker(.search('Vasa Museum Stockholm')).show();

Error Handling

show() throws MapLaunchException if the map cannot be opened:

try {
  await MapLauncher.marker(.coords(59.33, 18.07)).show(map: .google);
} on MapLaunchException catch (e) {
  print('Failed to open map: $e');
}

Directions

// Basic
await MapLauncher.directions(.coords(59.33, 18.07)).show();

// With origin, mode, and waypoints
await MapLauncher.directions(
  .coords(59.33, 18.07),
  from: .coords(59.33, 18.10, title: 'Djurgården'),
  mode: .walking,
  waypoints: [.coords(59.32, 18.08)],
).show();

// Search-based destination
await MapLauncher.directions(.search('Vasa Museum')).show();

// Search-based origin
await MapLauncher.directions(
  .coords(59.33, 18.07),
  from: .search('Stockholm Central'),
).show();

Choosing a Map

// Specific map
await MapLauncher.marker(.coords(59.33, 18.07)).show(map: .google);

// If map is omitted, the best available map is used automatically:
// • iOS/macOS → Apple Maps
// • Other platforms → Google Maps
// • Falls back to web if native app unavailable

Discovering Maps

// Maps that support a specific marker request
final marker = MapLauncher.marker(.coords(59.33, 18.07));
final maps = await marker.getSupportedMaps();
for (final map in maps) {
  print('${map.displayName} (installed: ${map.isInstalled})');
}

// Maps that support a specific directions request
final directions = MapLauncher.directions(.coords(59.33, 18.07), mode: .walking);
final navMaps = await directions.getSupportedMaps();

// All maps available on this platform (installed + universal link)
final allAvailable = await MapLauncher.getAvailableMaps();

URL Inspection

final marker = MapLauncher.marker(.coords(59.33, 18.07, title: 'Gamla Stan'));

// Best URL for this platform (scheme on mobile, universal on web)
final url = marker.getUrl(map: .google);

// Universal (HTTPS) URL — always works in browser
final universal = marker.getUniversalUrl(map: .google);
// → https://www.google.com/maps/search/?api=1&query=59.33%2C18.07

// Native scheme URL — only works with installed app
final scheme = marker.getSchemeUrl(map: .google);
// → comgooglemaps://?q=59.33,18.07

// Preview scheme URL for a different platform
final iosScheme = marker.getSchemeUrl(map: .google, platform: .ios);
final androidScheme = marker.getSchemeUrl(map: .google, platform: .android);

Map Info & Store Links

MapType properties are synchronous:

MapType.waze.displayName  // "Waze"
MapType.waze.icon         // asset path for SVG icon
MapType.waze.appStoreUrl  // "https://apps.apple.com/app/id323229106"
MapType.waze.playStoreUrl // "https://play.google.com/store/apps/details?id=com.waze"
MapType.waze.hasUniversalLink // true

Extras

Typed helper classes for map-specific parameters:

// Google — Place IDs, navigation mode
await MapLauncher.marker(.coords(59.33, 18.07)).show(
  map: .google,
  extra: GoogleExtra(queryPlaceId: 'ChIJLU7jZClu5kcR4PcOOO6p3I0'),
);

await MapLauncher.directions(.coords(59.33, 18.07)).show(
  map: .google,
  extra: GoogleExtra(navigate: true, destinationPlaceId: 'ChIJLU7j...'),
);

// Apple — map display type, search bias location
await MapLauncher.marker(.coords(59.33, 18.07)).show(
  map: .apple,
  extra: AppleExtra(display: AppleMapDisplay.satellite),
);

await MapLauncher.marker(.search('restaurants')).show(
  map: .apple,
  extra: AppleExtra(near: LocationCoords(59.33, 18.07)),
);

// Waze — auto-navigate
await MapLauncher.directions(.coords(59.33, 18.07)).show(
  map: .waze,
  extra: WazeExtra(navigate: true), // explicitly start navigation
);

// Tencent — API key
await MapLauncher.marker(.coords(39.9, 116.4)).show(
  map: .tencent,
  extra: TencentExtra(referer: 'your-app-key'),
);

// Yandex Navigator — auth
await MapLauncher.directions(.coords(55.75, 37.62)).show(
  map: .yandexNavi,
  extra: YandexNaviExtra(client: 'your-client-id', signature: 'your-sig'),
);

// Raw map — works with any map
await MapLauncher.marker(.coords(59.33, 18.07)).show(
  map: .apple,
  extra: {'t': 'k'}, // satellite view via raw params
);

Example — Bottom Sheet Picker

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

class MapPickerSheet extends StatelessWidget {
  final LocationCoords destination;
  final String title;

  const MapPickerSheet({
    required this.destination,
    required this.title,
  });

  @override
  Widget build(BuildContext context) {
    final request = MapLauncher.marker(destination);

    return FutureBuilder<List<SupportedMap>>(
      future: request.getSupportedMaps(),
      builder: (context, snapshot) {
        if (!snapshot.hasData) return const SizedBox.shrink();
        final maps = snapshot.data!;

        return SafeArea(
          child: SingleChildScrollView(
            child: Wrap(
              children: [
                for (final map in maps)
                  ListTile(
                    onTap: () => request.show(map: map.mapType),
                    title: Text(map.mapType.displayName),
                    leading: SvgPicture.asset(
                      map.mapType.icon,
                      height: 30,
                      width: 30,
                    ),
                  ),
              ],
            ),
          ),
        );
      },
    );
  }
}

// Usage
showModalBottomSheet(
  context: context,
  builder: (_) => MapPickerSheet(
    destination: .coords(59.33, 18.07, title: 'Gamla Stan'),
    title: 'Gamla Stan',
  ),
);

Known Issues

• On iOS it's possible to "delete" Apple Maps which actually just removes it from the home screen and does not actually delete it. Because of that Apple Maps will always show up as available on iOS. More info
