Example #

import 'package:flutter/material.dart';
import 'package:flutter_map/flutter_map.dart';
import 'package:geolocator/geolocator.dart';
import 'package:livemap/livemap.dart';
import 'package:latlong/latlong.dart';

class LiveMapPage extends StatelessWidget {
  LiveMapPage() () {
    mapController = MapController();
    liveMapController = LiveMapController(mapController: mapController);

  MapController mapController;
  LiveMapController liveMapController;

  Widget build(BuildContext context) {
    return Scaffold(
        body: LiveMap(
          mapController: mapController,
          liveMapController: liveMapController,
          mapOptions: MapOptions(
            center: LatLng(51.0, 0.0),
            zoom: 13.0,
          titleLayer: TileLayerOptions(
              urlTemplate: "https://{s}{z}/{x}/{y}.png",
              subdomains: ['a', 'b', 'c']),
        bottomNavigationBar: LiveMapBottomNavigationBar(
          liveMapController: liveMapController,

  void dispose() {

Changefeed #

A changefeed is available: it's a stream with all state changes from the map controller. Ex:

   import 'dart:async';

   StreamSubscription _changefeed;
   int _myzoom;

   liveMapController.onReady.then((_) {
       _myzoom = liveMapController.zoom;
       _changefeed = liveMapController.changeFeed.listen((change) {
        if ( == "zoom") {
          setState(() {
              _myzoom = change.value;

   // dispose: _changefeed.cancel();
