Flutter Google Places 自动填充仅适用于地区和子地区

我想通过 Google Places API 获取仅针对地区和次地区的建议，仅此而已。

我阅读了 Google Places 网站上的文档，看来这是不可能的。所有搜索还提供有关省份、国家、邮政编码等的建议。

请在下面找到我的代码片段：

     void getSuggestion(String input) async {
     String kPLACES_API_KEY = "API_KEY";
    String type = '(region)';
    String baseURL =
        'https://maps.googleapis.com/maps/api/place/autocomplete/json';
    String request =
        '$baseURL?input=$input&key=$kPLACES_API_KEY&sessiontoken=$_sessionToken&types=$type';
    var response = await http.get(Uri.parse(request));
    if (response.statusCode == 200) {
      setState(() {
        _placeList = json.decode(response.body)['predictions'];
      });
    } else {
      throw Exception('Failed to load predictions');
    }
  }

对此有任何解决方法吗？

I want to get the suggestions through Google Places API only for Localities and Sublocalities and nothing else.

I read the documentation on the Google Places Website and it seems that this is impossible. All searches also give suggestions on Provinces, Countries, Postal Codes and etc.

Please find my snippet below:

     void getSuggestion(String input) async {
     String kPLACES_API_KEY = "API_KEY";
    String type = '(region)';
    String baseURL =
        'https://maps.googleapis.com/maps/api/place/autocomplete/json';
    String request =
        '$baseURL?input=$input&key=$kPLACES_API_KEY&sessiontoken=$_sessionToken&types=$type';
    var response = await http.get(Uri.parse(request));
    if (response.statusCode == 200) {
      setState(() {
        _placeList = json.decode(response.body)['predictions'];
      });
    } else {
      throw Exception('Failed to load predictions');
    }
  }

Is there any workaround for this?
