,You just have no json['candidates'][0]. Try to print json and look at it's structure:

    var json = convert.jsonDecode(response.body);
    //var placeId = json['candidates'][0]['place_id'] as String;
    print(json);
    return "";

Also look if You enable Billing on the Google Cloud Project. If no it will return empty structure. And be careful, don't publish Your API key:

    final String _apiKey = 'AIz......';

Generate the new one, so nobody can use it!

Have a nice time!
