Description:

flutter json path

[FlutterJsonPath] in Dart #
A way to get and set json Map values using key paths! #

NOTE: A valid Map<String, dynamic> can be obtained using json encode/decode functions. This package will not work properly if your Map variable was initialized using Map Literals

Features #
Now you can read and write your json files without converting them to a model mapped version. Just use the key path to go directly where you want and get, set, delete or gen keys and values!
Installing #
Add FlutterJsonPath to your pubspec.yaml file:
dependencies:
flutter_json_path: latest_version

Import FlutterJsonPath in files that it will be used:
import 'package:flutter_json_path/flutter_json_path.dart';

Getting started #
Just create an instance of FlutterJsonPath and start working:
final parser = FlutterJsonPath();
final result = parser.gen('foo/bar/baz');
print('gen: $result'); // gen: {foo: {bar: baz: {}}}
copied to clipboard
Usage #
import 'dart:convert';
import 'package:flutter_json_path/flutter_json_path.dart';

void main() {
// Just to use as an example.
// This is Map Literals initialization.
Map<String, dynamic> target = {
'foo': {
'bar': {
'baz': 42,
},
},
};
// This package does not work with Map Literals.
// Must convert your Map to Json string and to Map again.
// (if this is the case)
target = jsonDecode(jsonEncode(target));

final parser = FlutterJsonPath();

var json1 = {...target};
var value = parser.get(json1, 'foo/bar/baz');
print('get: $value'); // get: 42

var json2 = {...target};
parser.set(json2, 'foo/bar', null);
print('set: $json2'); // set: {foo: {bar: CLUB}}

var json3 = {...target};
parser.delete(json3, 'foo/bar');
print('del: $json3'); // del: {foo: {}}
}
