json_utilities

Description:

json utilities

json_utilities #
Dart/Flutter package to enhance the experience of working with json based models.
Can be used in conjunction with json_serializable.
See Examples for more details.
General Idea #
The general/basic idea was to have something similar like lodash or ramda when working with 'JSON' / Map<String,dynamic>
in Dart.
Some operations like checking for existence of certain JSON leafs can be tedious, that's where this package is
supposed to come in and save the day!
This is a growing library, contributions are welcome!
Usage #
To use this plugin, add json_utilites as a dependency in your pubspec.yaml file
Examples #
Basic Example #
import 'package:json_utilities/json_utilities.dart';

var json = <String, dynamic>{
'root': 'value',
'root2': <String, dynamic>{'leaf': 'fruit'}
};

JSONUtils().get(json,'root.leaf', 'defaultValue') // returns String defaultValue
JSONUtils().get(json,'root', 'defaultValue') // returns String value
JSONUtils().get(json,'root2', 'defaultValue') // <String, dynamic>{'leaf': 'fruit'}
JSONUtils().get(json,'root.leaf.deeperLeaf', 'defaultValue') / returns String defaultValue

json_serializable Example #
// model/Condition.dart
import 'package:json_annotation/json_annotation.dart';

part 'Condition.g.dart';

@JsonSerializable()
class Condition {

String text;
String language;

Condition({this.text,this.language});

/*
* Json to Location object
*/
factory Condition.fromJson(Map<String, dynamic> json) =>
_$ConditionFromJson(json);

/*
* Location object to json
*/
Map<String, dynamic> toJson() => _$ConditionToJson(this);

}
