Simple Remote Config

A simple plugin for helping you to change your application's behaviors, settings,.. without updating the application via network JSON.

Features

• Fetch Remote Config via network JSON.
• Cache in-memory configs
• Provide get data via key and default value when data isn't found.

You can get started by looking at the example.

Install

Dart

dart pub add simple_remote_config

Flutter

flutter pub add simple_remote_config

First step

Android

Don't forget to add network permission in the Android manifest (AndroidManifest.xml)

<manifest xmlns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <application ...
</manifest>

macOS

macOS apps must allow network access in the relevant *.entitlements files.

<key>com.apple.security.network.client</key>
<true/>

How to use

Initialization

Create your SimpleRemoteConfig instance.

import 'package:simple_remote_config/simple_remote_config.dart';

final remoteConfig = SimpleRemoteConfig();

SimpleRemoteConfig has a param Client from http package so you can pass your custom Client object when create SimpleRemoteConfig instance.

import 'package:simple_remote_config/simple_remote_config.dart';
import 'package:http/http.dart' as http;

final client = http.Client();

final remoteConfig = SimpleRemoteConfig(client: client);

Fetch remote config data

SimpleRemoteConfig provides initilize function and you must pass an url to start fetching remote config data from network.

Remember: Url must return JSON format.

import 'package:simple_remote_config/simple_remote_config.dart';

final remoteConfig = SimpleRemoteConfig();

const configUrl = "https://dungngminh.github.io/remote_config/test.json";

await remoteConfig.initilize(configUrl: configUrl);

Get data from remote

SimpleRemoteConfig fetchs data in JSON format, data is returned in key-value format, you can key to get value via get functions, currently SimpleRemoteConfig supports String, int, double, bool, Map.

Example JSON format:

```json
{
    "key1": true, // boolean
    "key2": 10, // int
    "key3": "value from key 3", // string,
    "key4": {
        "key4_1": "value from key 4_1",
        "key4_2": 20
    }, // map
    "key5": 10.5 // double
}

And get data:

final valueKey1 = remoteConfig.getBool('key1');
print(valueKey1); // true

final valueKey2 = remoteConfig.getInt('key2');
print(valueKey2); // 10

final valueKey3 = remoteConfig.getString('key3');
print(valueKey3); // value from key 3

final valueKey4 = remoteConfig.getMap('key4');
print(valueKey4); // {key4_1: value from key 4_1, key4_2: 20}

final valueKey5 = remoteConfig.getDouble('key5');
print(valueKey5); // 10.5

If provided key is not found or provided T is incorrect, get functions will return null.

final valueKey7 = remoteConfig.getString('key7');
print(valueKey7); // null

You can pass defaultValue when get functions returns null.

final valueKey7 = remoteConfig.getString('key7', defaultValue: 'this is default value');
print(valueKey7); // this is default value

Get all data from remote

SimpleRemoteConfig provides getAll function to get all data from remote.

final allData = remoteConfig.getAll();
print(allData); /// {key1: true, key2: 10, key3: value from key 3, key4: {key4_1: value from key 4_1, key4_2: 20}, key5: 10.5}
