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(31.233568, 121.505504),
  title: "Shanghai Tower",
  description: "Asia's tallest building",
);

Check if map is installed and launch it

import 'package:map_launcher/map_launcher.dart';

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

Example using bottom sheet

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

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

class MapLauncherDemo extends StatelessWidget {
  openMapsSheet(context) async {
    try {
      final title = "Shanghai Tower";
      final description = "Asia's tallest building";
      final coords = Coords(31.233568, 121.505504);
      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,
                          description: description,
                        ),
                        title: Text(map.mapName),
                        leading: Image(
                          image: 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'),
            );
          },
        )),
