Place Tracker

A sample place tracking app that uses the google_maps_flutter plugin. Keep track of your favorite places, places you've visited, and places you want to go. View details about these places, show them on a map, and get directions to them.

Goals

Learn how to create an interface composed of GoogleMap and other widgets.
Learn how to show, control, and modify a GoogleMap widget.
Learn how to place a marker on a map.

The important bits

`place_map.dart`

This page shows a full-screen GoogleMap widget with place markers. Provides examples of how to stack other widgets on top of a GoogleMap widget, how to add markers to a map, and how to make other flutter widgets interact with the GoogleMap widget.

`place_details.dart`

This page shows a detailed view of a single place. Provides examples of how to place a GoogleMap widget inside of a ListView and how to disable certain touch gestures on the map.

Getting Started

To run this sample app, you will need an API key.

Get an API key at https://cloud.google.com/maps-platform/.

Android

Specify your API key in the application manifest android/app/src/main/AndroidManifest.xml:

<manifest ...
  <application ...
    <meta-data android:name="com.google.android.geo.API_KEY"
               android:value="YOUR KEY HERE"/>

iOS

Specify your API key in AppDelegate.swift:

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    GMSServices.provideAPIKey("YOUR API KEY HERE")
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Web

Add your API key to web/index.html in the <head> tag:

<script src="https://maps.googleapis.com/maps/api/js?key=<YOUR_API_KEY_HERE>"></script>

For additional help setting up the plugin, see the plugin's README page.

Caveat

The google_maps_flutter plugin is in developer preview until dynamic thread merging is finished.
