hn_easy_model #


A more easy way to do Flutter JSON serialization and deserialization.

Installation #

Add a dependency on hn_easy_model in your pubspec.

    hn_easy_model: any
    build_runner: any

Usage #

Initialization #


Create a dart file to aggregate headers. For example you created a dart file named easy_model_headers.dart.


Create a file named build.yaml,in the same path with pubspec.yaml. The content is as follows. lib/easy_model_headers.dart replace with right path.

          - lib/easy_model_headers.dart 


Switch to the command line run flutter packages pub run build_runner build. It will create a file named easy_model_headers.hneasymodel.dart.


At the beginning of the program import previous file import 'easy_model_headers.hneasymodel.dart';. Execute code initializeEasyModel();

Use model #


Model must extends HNEasyModel and annotation model with @hn_easy_model.

class Person extends HNEasyModel {
  int age;
  double weight;
  String name;
  bool married;
  Person mother;
  Person father;

0x22 json to model

Use hn_easyInitFromJson method, example model().hn_easyInitFromJson(map);

0x23 model to json

Use hn_easyToJson method, example model.hn_easyToJson();


While model change you need run flutter packages pub run build_runner build. If there is an error you can run flutter packages pub run build_runner build --delete-conflicting-outputs or just delete easy_model_headers.hneasymodel.dart file.

Supported #

  • [x] int
  • [x] double
  • [x] bool
  • [x] String
  • [x] Custom model (need annotation with@hn_easy_model)
  • [x] Map (cannot specify type)
