The json_helpers contains functions that make it easier decoding JSON objects directly from strings, lists and maps.

Version 0.0.1

Allows you to simplify decoding JSON objects directly from String, List and Map values.

Examples (better examples comming soon):

import 'dart:convert';

import 'package:json_helper/json_helper.dart';
import 'package:test/test.dart';

void main() {
  final data1 = Data(name: 'test1');
  final data2 = Data(name: 'test1');
  final dataList = [data1, data2];
  final dataMapList = [data1.toJson(), data2.toJson()];
  final data1AsString = jsonEncode(data1);
  Map data1AsMap = data1.toJson();
  final dataListAsString = jsonEncode(dataList);
  test('String.decodeJson', () {
    final result = data1AsString.decodeJson((e) => Data.fromJson(e));
    expect(result, data1);
  });

  test('String.decodeJsonList', () {
    final result = dataListAsString.decodeJsonList((e) => Data.fromJson(e));
    expect(result, dataList);
  });

  test('Map.fromJson', () {
    final result = data1AsMap.fromJson((e) => Data.fromJson(e));
    expect(result, data1);
  });

  test('List.fromJson', () {
    final result = dataMapList.fromJson((e) => Data.fromJson(e));
    expect(result, dataList);
  });
}

class Data {
  final String name;

  Data({required this.name});

  factory Data.fromJson(Map<String, dynamic> json) {
    return Data(name: (json['name'] as String?) ?? '');
  }

  @override
  bool operator ==(other) {
    if (other is Data) {
      return name == other.name;
    }

    return false;
  }

  Map<String, dynamic> toJson() => {'name': name};
}

New features will be added soon...
