IMPORTANT: This plugin is no longer under development


We initially built this plugin to fill an early gap in flutter. Since then, Google has made progress on their Google Map plugin.

Meanwhile, at AppTree, we've moved on to building a pure Dart implementation for mapping based off of leaflet, which you can find here. This plugin has the following important features:

  • Allows inline maps within your Widget hierarchy (rather than full screen)
  • Pins are just widgets. Very easy to customize
  • 0 dependencies on native libraries. No more Google Play or Cocoapod dependencies!
  • You can use any OpenStreetMap tiles as well as paid tile providers like MapBox and ESRI. Unfortunately, Google Map tiles are not available. You can find more about available tile providers here.


A flutter plugin for displaying google maps on iOS and Android

Please note: API changes are likely as we continue to develop this plugin.

Getting Started

Generate your API Key

  1. Go to:
  2. Enable Maps SDK for Android
  3. Enable Maps SDK for iOS
  4. Under Credentials, choose Create Credential.
    • Note: For development, you can create an unrestricted API key that can be used on both iOS & Android. For production it is highly recommended that you restrict.

The way you register your API key on iOS vs Android is different. Make sure to read the next sections carefully.


The maps plugin will request your users location when needed. iOS requires that you explain this usage in the Info.plist file

  1. Set the NSLocationWhenInUseUsageDescription in ios/Runner/Info.plist. Example:
    <string>Using location to display on a map</string>
  1. Prior to using the Map plugin, you must call MapView.setApiKey(String apiKey). Example:
   import 'package:map_view/map_view.dart';
   void main() {
     runApp(new MyApp());

Note: If your iOS and Android API key are different, be sure to use your iOS API key here.

  1. Add code to show the MapView.

    //Create an instance variable for the mapView
    var _mapView = new MapView();
    //Add a method to call to show the map.
    void showMap() { MapOptions(showUserLocation: true));
  2. Run your application on an iOS device or simulator. Confirm that when you display the map you see map detail. If you only see a beige screen it's possible that your API key is incorrect. When your API key is incorrect you'll see messages like this in the console:

ClientParametersRequest failed, 7 attempts remaining (0 vs 12). Error Code=400 "(null)" UserInfo={data=<>}

Common API Key problems for iOS

  1. Your Bundle ID does not match what is registered in the Google API Console. When you create an restricted API key in the Google API console it asks you to specify your iOS bundle ID. Make sure that your iOS Bundle Identifier matches the one you registered in the console.

  2. Using the wrong key. If you made a separate key for iOS and Android, make sure you are using the iOS key in the MapView.setApiKey() call.


You will be making multiple edits to your AndroidManifest.xml file. In your Flutter project, you can find this file location under android/app/src/main

  1. In your AndroidManifest.xml, add the following uses-permission above the tag.

        <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
        <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
  2. In your AndroidManifest.xml, add the following lines inside of the application tag. Be sure to replace your_api_key with the one you generated.

        <meta-data android:name="" android:value="your_api_key"/>
        <meta-data android:name="" android:value="@integer/google_play_services_version"/>
  3. Add the MapActivity to your AndroidManifest.xml

        <activity android:name="com.apptreesoftware.mapview.MapActivity" android:theme="@style/Theme.AppCompat.Light.DarkActionBar"/>
  4. In your android/build.gradle file. Under buildScript dependencies add:

        classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.1.2-4'
  5. Run your application on an Android device or simulator. Confirm that when you display the map you see map detail. If you only see a beige screen it's possible that your API key is incorrect.

Static Maps for Inline display

This plugin does not currently support displaying a Google Map within the Flutter widget hierarchy. A common workaround for this is to show a static image using the Google Static Maps API. Included in this Plugin is the StaticMapProvider class which will allow you to easily generate a static map. The Static Maps API also requires an API Key and you must enable the API within the Google API Console.

  1. Go to:
  2. Enable Maps Static API
  3. Once enabled, you can use the same API key you generated for iOS/Android.
  4. Initialize the StaticMapProvider
    var provider = new StaticMapProvider('your_api_key');
  5. The StaticMapProvider offers a few different APIs for generating static maps. If you want to generate an image for the current viewport of your full screen interactive map you can use:
var uri = staticMapProvider.getImageUriFromMap(mapView,
                  width: 900, height: 400);

You can refer to the example project if you run into any issues with these steps.

Usage examples

Show a map ( with a toolbar )
        new MapOptions(
            mapViewType: MapViewType.normal,
            showUserLocation: true,
            initialCameraPosition: new CameraPosition(
                new Location(45.5235258, -122.6732493), 14.0),
            title: "Recently Visited"),
        toolbarActions: [new ToolbarAction("Close", 1)]);

Get notified when the map is ready

mapView.onMapReady.listen((_) {
  print("Map ready");

Add multiple pins to the map

    new Marker("1", "Work", 45.523970, -122.663081, color:,
    new Marker("2", "Nossa Familia Coffee", 45.528788, -122.684633),

Add a single pin to the map

mapView.addMarker(new Marker("3", "10 Barrel", 45.5259467, -122.687747,
        color: Colors.purple));

Edit custom Marker image

First add your assets to a folder in your project directory. The name of the folder could be any but "images" or "assets" are the more common. It should look like this.

- project_name
    # Rest of project folders and files

Then add asset to the pubspec.yaml under flutter tag.

    # Code already existent

    # Added asset.
        - images/flower_vase.png

Finally use the asset name as icon for your marker. If the width or height is not set or is equals to 0, the image original value of said attribute will be used.

new Marker(
      "Something fragile!",
      draggable: true, //Allows the user to move the marker.
      markerIcon: new MarkerIcon(
        "images/flower_vase.png", //Asset to be used as icon
        width: 112.0, //New width for the asset
        height: 75.0, // New height for the asset

Set a Marker draggable and listening to position changes

First set the draggable attribute of a marker to true.

Marker marker=new Marker(
      "Something fragile!",
      draggable: true, //Allows the user to move the marker.

Now add listeners for the events.

// This listener fires when the marker is long pressed and could be moved.
mapView.onAnnotationDragStart.listen((markerMap) {
      var marker = markerMap.keys.first;
      var location = markerMap[marker]; // The original location of the marker before moving it. Use it if needed.
      print("Annotation ${} dragging started");
// This listener fires when the user releases the marker.
mapView.onAnnotationDragEnd.listen((markerMap) {
      var marker = markerMap.keys.first;
      var location = markerMap[marker]; // The actual position of the marker after finishing the dragging.
      print("Annotation ${} dragging ended");
// This listener fires every time the marker changes position.
mapView.onAnnotationDrag.listen((markerMap) {
      var marker = markerMap.keys.first;
      var location = markerMap[marker]; // The updated position of the marker.
      print("Annotation ${} moved to ${location.latitude} , ${location

Add a single polyline to the map

mapView.addPolyline(new Polyline(
            new Location(45.519698, -122.674932),
            new Location(45.516687, -122.667014),
          width: 15.0));

Add multiple polylines to the map

        new Polyline(
            new Location(45.523970, -122.663081),
            new Location(45.528788, -122.684633),
            new Location(45.528864, -122.667195),
          jointType: FigureJointType.round,
          width: 15.0,
          color: Colors.orangeAccent,
        new Polyline(
            new Location(45.519698, -122.674932),
            new Location(45.516687, -122.667014),
          width: 15.0,

Add a single polygon to the map

mapView.addPolygon(new Polygon(
                                   new Location(45.5231233, -122.6733130),
                                   new Location(45.5233225, -122.6732969),
                                   new Location(45.5232398, -122.6733506),
                                   new Location(45.5231233, -122.6733130),
                                 jointType: FigureJointType.round,
                                 strokeWidth: 5.0,
                                 fillColor: Color.fromARGB(75, 255, 0, 0),

Add multiple polygons to the map

        new Polygon(
              new Location(42.9274334, -72.2811234),
              new Location(42.9258230, -72.2808444),
              new Location(42.9261294, -72.2779906),
              new Location(42.9275120, -72.2779155),
            //you can add a hole inside the polygon
            holes: <Hole>[
              new Hole(
                  new Location(42.9270721, -72.2797287),
                  new Location(42.9266400, -72.2796750),
                  new Location(42.9267186, -72.2790956),
                  new Location(42.9270014, -72.2790956),
            jointType: FigureJointType.round,
            strokeWidth: 5.0,
            fillColor: Color.fromARGB(75, 255, 0, 0)),
        new Polygon(
              new Location(45.5231233, -122.6733130),
              new Location(45.5233225, -122.6732969),
              new Location(45.5232398, -122.6733506),
