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';

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),
    );
  }
}

Example

Here is an example of a basic form screen build with Mirai.

Flutter

import 'package:flutter/material.dart';
import 'package:mirai/mirai.dart';

void main() {
  runApp(const MyApp());
}

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

  @override
  Widget build(BuildContext context) {
    return MiraiApp(
      title: 'Mirai Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: Mirai.fromNetwork(
        MiraiRequest(
          url: _url,
          method: Method.get,
        ),
      ),
    );
  }
}

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.
