How to open an application from a Flutter app?

Question

I am developing a Flutter app, in which I need to show navigation to the user for a place. So, how can I open a map application from my Flutter app like we do using external

Answer 1

You can just use the url_launcher plugin to open maps. It launches map if installed or falls back to open the map on a browser.

Example:

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

void main() {
  runApp(new Scaffold(
    body: new Center(
      child: new RaisedButton(
        onPressed: _launchURL,
        child: new Text('Launch Maps'),
      ),
    ),
  ));
}

_launchMaps() async {
  const url = "https://www.google.com/maps/search/?api=1&query=LATITUDE,LONGITUDE,17&query_place_id=PLACE_ID";
  if (await canLaunch(url)) {
    await launch(url);
  } else {
    throw 'Could not launch Maps';
  }
}

Hope that helps!
