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 create keys and values!

Installing

Add JsonByPath to your pubspec.yaml file:

dependencies:
  json_by_path:

Import JsonByPath in files that it will be used:

import 'package:json_by_path/json_by_path.dart';

Getting started

Just create an instance of JsonByPath and start working:

    JsonByPath jbp = JsonByPath();
    String v = jbp.getValue(target, 'config.tcp.url');
    int i = jbp.getValue(target, 'config.tcp.port');
    jbp.setValue(target)

Usage

import 'dart:convert';
// just to use as an example, this is Map Literals initialization
Map<String, dynamic> target = {
    'config': {
        'tcp': {
            'url': 'http://localhost',
            'port': 8083
        }
    }
};

// this package does not work with Map Literals
// convert your map to json string and to Map again
// (if this is the case)
target = json.decode(json.encode(target));

JsonByPath jbp = JsonByPath();

print(jbp.getValue(target, 'config.tcp.url'));
jbp.setValue(target, 'config.tcp.doLog', true);
print(target);
