json_to_ui

json_to_ui is a Flutter package that enables dynamic UI generation from JSON configurations. It simplifies building flexible and dynamic user interfaces, making it ideal for applications that require runtime UI changes or user-generated layouts.

Features

• Dynamic UI Rendering: Generate Flutter widgets such as Scaffold, Container, Text, Button, and more from JSON.
• Customizable Styling: Apply colors, fonts, padding, borders, and other styles via JSON.
• Supports Common Widgets: Works with Text, Row, Column, Container, Padding, ElevatedButton, etc.
• Hive Integration: Store and retrieve JSON-based UI configurations locally for offline support.
• Network Fetching: Load UI configurations from a remote server via HTTP requests.

Example Flutter Code

Use this Flutter code to render the UI from a network JSON request:

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: JsonNetworkUiBuilder.fromNetwork(
        request: NetworkRequest(
          url: 'https://raw.githubusercontent.com/atiquehossain/testjson/refs/heads/main/testservermain.json',
          method: Method.get,
        ),
        isSaveOnHive: true,
      ),
    );
  }
}
