Flutter MapLibre GL

Free

Starter

Standard

Professional

Flutter MapLibre GL is a Flutter wrapper around MapLibre Native and MapLibre GL JS which we recommend for most Flutter users building an iOS/Android app with vector maps. This quickstart guide shows you the quickest way to get a map in your app.

Quickstart

First, add the library to your pubspec under dependencies.

pubspec.yaml
dependencies:
  ...
  maplibre_gl:
    git:
      url: https://github.com/maplibre/flutter-maplibre-gl.git
      ref: main

Tip

You can pin to a release branch rather than main for stability. Note that the library is still under fairly active development and has not yet hit a v1.0 release.

Second, add the necessary dependencies to your Podfile.

iOS/Podfile
source 'https://github.com/m0nac0/flutter-maplibre-podspecs.git'

pod 'MapLibre'
pod 'MapLibreAnnotationExtension'

Finally, you're ready to instantiate a MaplibreMap widget and add it to your app! Here is an example of how to use it with a Stadia Maps vector style.

const styleUrl = "https://tiles.stadiamaps.com/styles/alidade_smooth_dark.json";
const apiKey = "YOUR-API-KEY";
MaplibreMap(
  styleString: "$styleUrl?api_key=$apiKey",
  myLocationEnabled: true,
  initialCameraPosition: const CameraPosition(target: LatLng(0.0, 0.0)),
  trackCameraPosition: true,
)

Tip

You can browse our map style library for additional map styles, or create your own.

Sign up for a Stadia Maps API key

Before you can run this, you'll need a Stadia Maps API key. You can sign up for free, and no credit card is required! After signing up, create a property and an API key (there's a button at the bottom of the property detail page in the dashboard).

Warning

Make sure to test your application thoroughly on all platforms that you target. In our experience, even trivial applications can exhibit differing behavior and/or subtle bugs on one or more platforms.

If you are targeting web, you should additionally make sure to add the MapLibre GL JS script reference in the head section of your index.html.

<head>
    <!-- MapLibre GL JS -->
    <script src="https://unpkg.com/maplibre-gl@3.6.2/dist/maplibre-gl.js"></script>
    <link href="https://unpkg.com/maplibre-gl@3.6.2/dist/maplibre-gl.css" rel="stylesheet" />

Next Steps

We have published a full example repository on GitHub which visualizes a set of earthquake data. This is analogous to the cluster example for MapLibre GL JS.

The Flutter MapLibre GL GitHub repo is the authoritative source for documentation and further information. You can find browsable API documentation hosted here.
