    Chắc em cần paste code của em xem anh có làm gọn hơn được không thôi chứ bản chất Isolate nó cũng chỉ là 1 cái event loop, anh nghĩ cũng không có gì đơn giản hơn nữa em ạ.

      Hi a,
      Bây giờ em có khá nhiều usecase cần sử dụng khoảng 10 method có trong local repository (database query heavy search & similarity search). Có cách nào để hạn chế phải viết 10 cái top-level function kia ko ạ, hoặc a có từng dùng lib nào đỡ boilerplate code thì cũng giảm được effort ạ.
      Thank a.

        This answer was edited.

        Vậy tức là câu hỏi của em là: có thư viện nào có thể giảm được số lượng dòng code phải viết cho 10 method kia đúng không em? Nếu đúng, em có thể dùng thư viện rxdart nhé.

          Dạ đúng ạ,
          Em đang tham khảo lib này:
          https://github.com/alphamikle/isolator
          anh có từng dùng lib khác, hoặc từng viết riêng thành 1 module để reuse code cho vụ này thì cho em tham khảo ạ
          Thank a

    Nếu vậy, anh thấy em có thể tách thành lớp DataFetcher để common code em ạ:

    class Data {
      late String data1;
      late String data2;
    
      String toJson() {
        return '{"data1":' + data1 + ',' + '"data2": ' + data2 + '}';
      }
    }
    
    class DataFetcher {
      Data getData() {
        var data = new Data();
        data.data1 = 'data1';
        data.data2 = 'data2';
        return data;
      }
    }
    
    void getData(SendPort sendPort) {
      var data = DataFetcher().getData();
      sendPort.send(data.toJson());
    }
    
    void getDataAsync() async {
      var receivePort= ReceivePort(); //port for isolate to receive messages.
      var isolate = await Isolate.spawn(getData, receivePort.sendPort);
      receivePort.listen((data) {
        stdout.write('Receiving: ' + data + ', ');
        isolate.kill();
      });
    }
    
    void main(){
      getDataAsync();
    }
