'Place Picker Null Result

I am using Flutter Place Picker 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;

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

flutter

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:

In the code below press CTRL(cmd for MAC) on PlacePicker() and navigate to place_picker.dart file:

void showPlacePicker() async {
LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
    builder: (context) =>
        PlacePicker("YOUR_API_KEY")));
print(result);

}

Inside place_picker.dart file of the library replace the whole method void reverseGeocodeLatLng(LatLng latLng) async{....} with the following:

 void reverseGeocodeLatLng(LatLng latLng) async {
try {
  final response = await http.get(
      "https://maps.googleapis.com/maps/api/geocode/json?" +
          "latlng=${latLng.latitude},${latLng.longitude}&" +
          "key=${widget.apiKey}");

  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 &&
        result['address_components'].length >= 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);
}

}

Close the app. Uninstall it and Run it once again your problem will be solved.

Note: Maps SDK for Android, Places API, and Geocoding API must be enabled for using place_picker.

I had to enable Geocoding API:

Solution 4:^[4]

Try this.

Void showPlacePicker() async {
    LocationResult result = await Navigator.of(context).push(MaterialPageRoute(
        builder: (context) =>
            PlacePicker("your_api_key",
                        displayLocation: customLocation,
                        )));
    print(result);
}
