How to do it...

To add markers to the map in your project, perform the following steps:

import 'package:http/http.dart' as http;
import 'dart:convert';

3. At the top of the _MyMapState class, and a new List of Marker objects:

class _MyMapState extends State<MyMap> {
LatLng userPosition;
List<Marker> markers = [];

4. In the AppBar contained in the build method of the _MyMapState class, add the actions property, containing an IconButton, which, when pressed, calls a findPlaces method that we will create in the next steps:

@override
Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
