In addition to enabling Places API, Maps SDK for Android and Maps SDK for iOS for the API key, you should also enable Geocoding API. I hope the documentation will be updated.

Follow the steps below and your issue will be solved:
<ol>
<li>In the code below press CTRL(cmd for MAC) on PlacePicker() and navigate to place_picker.dart file:
<pre><code>void showPlacePicker() async {
LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
 builder: (context) =&gt;
 PlacePicker(&quot;YOUR_API_KEY&quot;)));
print(result);
</code></pre>
}
</li>
<li>Inside place_picker.dart file of the library replace the whole method
<code>void reverseGeocodeLatLng(LatLng latLng) async{....}</code> with the following:
<pre><code> void reverseGeocodeLatLng(LatLng latLng) async {
try {
 final response = await http.get(
 &quot;https://maps.googleapis.com/maps/api/geocode/json?&quot; +
 &quot;latlng=${latLng.latitude},${latLng.longitude}&amp;&quot; +
 &quot;key=${widget.apiKey}&quot;);

 if (response.statusCode != 200) {
 throw Error();
 }

 final responseJson = jsonDecode(response.body);
 print('Google maps response body ' + response.body);

 if (responseJson['results'] == null) {
 throw Error();
 }

 final result = responseJson['results'][0];

 setState(() {
 if (result['address_components'] is List &amp;&amp;
 result['address_components'].length &gt;= 7) {
 this.locationResult = LocationResult()
 ..name = result['address_components'][0]['short_name']
 ..locality = result['address_components'][1]['short_name']
 ..latLng = latLng
 ..formattedAddress = result['formatted_address']
 ..placeId = result['place_id']
 ..postalCode = result['address_components'][7]['short_name']
 ..country = AddressComponent.fromJson(
 result['address_components'][6])
 ..administrativeAreaLevel1 = AddressComponent.fromJson(
 result['address_components'][5])
 ..administrativeAreaLevel2 = AddressComponent.fromJson(
 result['address_components'][4])
 ..city = AddressComponent.fromJson(result['address_components'][3])
 ..subLocalityLevel1 = AddressComponent.fromJson(
 result['address_components'][2])
 ..subLocalityLevel2 = AddressComponent.fromJson(
 result['address_components'][1]);
 }
 else {
 this.locationResult = LocationResult()
 ..latLng = latLng
 ..formattedAddress = result['formatted_address']
 ..placeId = result['place_id']
 ..name = result['address_components'][0]['short_name']
 ..locality = result['address_components'][1]['short_name']
 ..administrativeAreaLevel1 = AddressComponent.fromJson(
 result['address_components'][2])
 ..city = AddressComponent.fromJson(result['address_components'][3])
 ..country = AddressComponent.fromJson(
 result['address_components'][4]);
 }
 });
} catch (e) {
 print(e);
}
</code></pre>
}
</li>
<li>Close the app. Uninstall it and Run it once again your problem will be solved.
</li>
</ol>
Note: Maps SDK for Android, Places API, and Geocoding API must be enabled for using place_picker.

I am using <a href="https://pub.dev/packages/place_picker" rel="nofollow noreferrer">Flutter Place Picker</a> to select a location but the results are null.

I have used the example provided but I am getting NULL result with "Unnamed Location" as per the photo below;

<pre><code> void showPlacePicker() async {
 LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
 builder: (context) =&gt;
 PlacePicker("AIzaSyBJ4Q0lFgGPr6at5IXD6j5YLAFuAKe1Nbo")));
 print(result);
 }
</code></pre>
