Shows a places picker dialog in ios and android, returning the data in the places picker to the app.
Generate your API Key
- Go to: https://console.developers.google.com/
Google Maps Android API
Google Maps SDK for iOS
- 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.
- More detailed instructions for Android can be found here: https://developers.google.com/maps/documentation/android-api/signup
- More detailed instructions for iOS can be found here: https://developers.google.com/maps/documentation/ios-sdk/get-api-key
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
- Set the NSLocationWhenInUseUsageDescription in
<key>NSLocationWhenInUseUsageDescription</key> <string>Using location to display on a map</string>
Note: If your iOS and Android API key are different, be sure to use your iOS API key here.
- Add code to show the MapView.
//Create an instance variable for the mapView var _place = await FlutterPlacesDialog.getPlacesDialog();
- 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, or if it outright crashes.
Common API Key problems for iOS
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.
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
AndroidManifest.xml, add the following uses-permission above the
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
In your AndroidManifest.xml, add the following lines inside of the
applicationtag. Be sure to replace
your_api_keywith the one you generated.
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your_api_key"/> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>
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.
Show the places picker ( with autocomplete )
PlaceDetails place = await FlutterPlacesDialog.getPlacesDialog();
Dialog shows up and drops almost immediately
Verify you have your google api key setup correctly. If using iOS you need to set this via the API call, on android you need to setup the google-services.json correctly in your app deployment or it will not correctly show the screen, dropping out basically immediately. You should get an error back from the api call to the client saying it dropped.
