flutter_map

Flutter's №1 non-commercially aimed map client: it's easy-to-use, versatile, vendor-free, fully cross-platform, and 100% pure-Flutter

Welcome to v8! Find out What's New In v8?, or if you're new here, check out the Code Demo & Installation instructions to get started.

v7 documentation is still available: v7. Some plugins may require some time to update to support v8.

Why choose flutter_map?

🗺️ No more vendor lock-in: better flexibility, quality, and price

We natively support any static tiles! Bring your own tiles from your own server, the user's device, a tile container, or another externally-operated tile server. Use any service, but always be free to change to get the best fit, quality, and price.

Still want to use those familiar maps? Consider great quality and better priced alternatives, or use the more mainstream Google Maps or Mapbox Maps with flutter_map.

🚀 Stress-free setup & easy-to-use

Migrating from a commercial library (such as Google Maps) has never been easier. No more complex platform-specific setup, no more buggy & limited platform views (we're 100% pure-Flutter), and no more lacking-documentation & support. Just setup a simple widget, grab a string from your tile server, and you're done! And, it'll work across all the platforms Flutter supports. Check out our Code Demo to see just how simple it is.

🧩 Customize and expand endlessly

Add interactive and highly customizable polygons, polylines, and markers (which support widget children) to your map easily and quickly. And because we're 100% Flutter, it's easy to add your own stuff on top without messing around in platform views. A huge community of developers maintain an ecosystem of plugins for you to supercharge flutter_map with.

👋 But don't just take it from us...

Hundreds of thousands of apps and users choose flutter_map for mapping in their Flutter app, making us Flutter's №1 non-commercially aimed map client on pub.dev. Check out some independent reviews, comparisons, and studies, and see who's using flutter_map right now: Showcase & Case Studies

🌟Showcase & Case Studies

If you're looking for vector tiles, we don't currently support them natively. We only support raster tiles at the moment.

However, options are available, and the we and the community are actively exploring & developing future support!

Code Demo

Setting up an interactive and map is simpler than making your lunch-time coffee! It can be accomplished in just under 30 lines and a minute or two to install.

This code snippet demonstrates everything you need for a simple map (in under 30 lines!), but of course, FM is capable of much more than just this, and you could find yourself lost in the many options available and possibilities opened!

import 'package:flutter_map/flutter_map.dart';
import 'package:latlong2/latlong.dart';

@override
Widget build(BuildContext context) {
  return FlutterMap(
    options: MapOptions(
      initialCenter: LatLng(51.509364, -0.128928), // Center the map over London
      initialZoom: 9.2,
    ),
    children: [
      TileLayer( // Bring your own tiles
        urlTemplate: 'https://tile.openstreetmap.org/{z}/{x}/{y}.png', // For demonstration only
        userAgentPackageName: 'com.example.app', // Add your app identifier
        // And many more recommended properties!
      ),
      RichAttributionWidget( // Include a stylish prebuilt attribution widget that meets all requirments
        attributions: [
          TextSourceAttribution(
            'OpenStreetMap contributors',
            onTap: () => launchUrl(Uri.parse('https://openstreetmap.org/copyright')), // (external)
          ),
          // Also add images...
        ],
      ),
    ],
  );
}

FAQs

We get quite a lot of similar questions, so please check if your question is here before you ask!

❔How Does It Work?

How can I use a custom map style? How can I prevent POI/labels rotating when the map rotates? How can I remove certain POI/labels from the map?

Unfortunately, this library cannot change the tiles you give it: it has no control over the tiles displayed in the TileLayer. This is a limitation of the technology, not this library.

This is because raster tiles are just images generated by a 3rd party tile server (dictated by your URL template), and therefore cannot be changed by the library that displays the tiles. Filters can be applied to the entire tile, such as an emulated dark mode, but these effects do not look great.

However, tilesets can be styled. This is the most effective way of using custom styles. These methods may help you with this:

• You may wish to use a commercial service like Mapbox Studio, which allows you to style multiple tilesets. See Using Mapbox.

• Alternatively, you can experiment with vector tiles. These are not pre-rendered, and so allow any style you desire to be applied on the fly. See Vector Tiles.
• Your last option is to serve tiles yourself. See Other Options.

How can I route a user between two locations? Why does the Polyline only go in a straight line between two points?

See Routing/Navigation.

How can I add a Marker where the user's location is? How can I center the map on the user's location?

This is beyond the scope of flutter_map. However, you can use the community maintained plugin 'flutter_map_location_marker' to do this.

Alternatively, use the 'location' and 'compass' packages to generate a stream of the user's location and heading, and feed that to a Marker using a StreamBuilder.

Why don't any map tiles appear?

If no tiles are appearing (if tiles are appearing on some zoom levels but not others, see below), try performing the following debugging steps:

1. Is the templateUrl or WMS configuration correct (to the best of your knowledge)?

2. Have you followed the platform specific setup (Additional Setup) instructions (if applicable for your platform)?
3. Check the Network tab either in Flutter DevTools or the browser DevTools to see why/if the tile requests are failing.

4. If none of those solved the issue, check if there are any widgets covering the map, or any errors in the console (particularly in release mode)?

Why does the map disappear/go grey when I zoom in far? Why does the map stop zooming in even though I know there are more zoom levels?

If tiles are disappearing when you zoom in, the default grey background of the FlutterMap widget will shine through. This usually means that the tile server doesn't support these higher zoom levels.

If you know that there are more tiles available further zoomed in, but flutter_map isn't showing them and scaling a particular zoom level instead, it's likely because the TileLayer.maxNativeZoom property is set too low (it defaults to 19).

To set/change the zoom level at which FM starts scaling tiles, change the TileLayer.maxNativeZoom property. To set/change the max zoom level that can actually be zoomed to (hard limit), use MapOptions.maxZoom.

How can I make the map 3D, or view it as a globe?

Unfortunately, this isn't supported, partially due to lack of time on the maintainer's part to implement this feature, partially due to technical limitations. PRs are welcome!
