我正在尝试对搜索进行 API 调用，并基于此我必须构建一个小部件。

这样对吗？

class DataSearch extends SearchDelegate<Future<Widget>> {

  Future serachdb(searchData) async {    
    var url = '$_globalUrl/api/searchdata';
    var param = {'searchby': searchData};
    var result = await http.post(url, body: param);
    if (result.body != '') {
      userData = json.decode(result.body);
    }
  }

  @override
  Widget buildResults(BuildContext context) {
    serachdb(query);  // it doesn't wait untill this completes  
    return resultContent();
  }

  Widget resultContent(){
    return new Scaffold(
      /*
      some code
      */
    );
  }
}
