Steps to Integrate Google Maps in Flutter


Step 1: Import Flutter Library

Add google_maps_flutter library to pubspec.yaml

  google_maps_flutter: ^0.5.28+1
Step 2: Get Google Maps API Key

Follow article on Get an API Key | Maps SDK for Android, Activate Library "Maps SDK for Android" & "Maps SDK for iOS" and get API Key. Once Done edit file AndroidManifest.xml:

<manifest ...
  <application ...
    <meta-data android:name=""

Now open ios/Runner/AppDelegate.m and put lines as shown:

#include "AppDelegate.h"
#include "GeneratedPluginRegistrant.h"
#import "GoogleMaps/GoogleMaps.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  // Add the following line with your API key.
  [GeneratedPluginRegistrant registerWithRegistry:self];
  return [super application:application didFinishLaunchingWithOptions:launchOptions];

You will also need to enable embedded_views_preview in file Info.plist:

Step 3: Import SDK for iOS

Once this is done we have to make sure that Google Maps SDK is available to XCode. To do that we need to update few things.

Open file Podfile and uncomment following line:

platform :ios, '9.0'

Now open your ios folder from XCode as a Project and then open file Runner as show in image below. here change the deployment target to 9.0 as shown.

Once done. Close XCode and run following command in folder /ios in terminal:

sudo gem install cocoapods
pod update

This will successfully update your pod and then we can move ahead with creating our first Map Screen:

Step 4: Create first Map Widget
import 'dart:async';
import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class GoogleMapApp extends StatefulWidget {
  _GoogleMapAppState createState() => _GoogleMapAppState();

class _GoogleMapAppState extends State<GoogleMapApp> {
  Completer<GoogleMapController> _controller = Completer();

  static const LatLng centerLoc = const LatLng(45.521563, -122.677433);

  void _onMapCreated(GoogleMapController controller) {

  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Google Map Example'),
          backgroundColor: AppTheme.topBarColor,
          leading: IconButton(
            icon: Icon(Icons.arrow_back, color: AppTheme.white),
            onPressed: () => Navigator.of(context).pop(),
        body: GoogleMap(
          onMapCreated: _onMapCreated,
          initialCameraPosition: CameraPosition(
            target: centerLoc,
            zoom: 8.0,

Here we go
