mirai

Mirai is a Server-Driven UI (SDUI) library for Flutter. Mirai allows you to build beautiful cross-platform applications with JSON in real time.
Developed with 💙 by Securrency
Installation 🚀 #
First, we need to add Mirai to our pubspec.yaml file.
Install the plugin by running the following command from the project root:
flutter pub add mirai

Usage 🧑‍💻 #
Now that we have successfully installed Mirai, we can import Mirai in main.dart.
import 'package:mirai/mirai.dart';
copied to clipboard
Next, within main function initialize Mirai.
void main() async {
await Mirai.initialize();

runApp(const MyApp());
}

You can also specify your custom Parsers in Mirai.initialize and Dio instance.
void main() async {
final dio = Dio();

await Mirai.initialize(
parsers: const [
ExampleScreenParser(),
],
dio: dio,
);

runApp(const MyApp());
}

Finally, replace your MaterialApp with MiraiApp. And call your json with Mirai.fromJson(json, context).
import 'package:flutter/material.dart';
import 'package:mirai/mirai.dart';

void main() async {
await Mirai.initialize();

runApp(const MyApp());
}

class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);

@override
Widget build(BuildContext context) {
return MiraiApp(
title: 'Mirai Demo',
homeBuilder: (context) => Mirai.fromJson(json, context),
);
}
}

Note:
Mirai provides multiple methods to parse JSONs into Flutter widgets. You can use Mirai.fromNetwork(), Mirai.fromJson() & Mirai.fromAsset()

That's it with just few lines of code your SDUI app is up and running.
