FlowXML #

A modern Flutter library that converts XML code into Flutter components with real-time streaming support. Perfect for AI chat interfaces, dynamic content rendering, and real-time data visualization.

🚀 Features #

• 🔄 Real-time Streaming: Handle partial XML content as it streams from APIs
• 🧩 Dynamic Components: Automatically convert XML tags into interactive Flutter widgets
• 🎨 Customizable: Easy to add custom component types and styling
• 📱 Flutter Native: Built specifically for Flutter with Material Design 3 support
• ⚡ High Performance: Efficient parsing and rendering with minimal overhead
• 🛡️ Error Resilient: Graceful handling of malformed or incomplete XML
• 📦 Extensible: Modular architecture for easy expansion

📦 Installation #

Add FlowXML to your pubspec.yaml:

dependencies:
  flowxml: ^1.0.0

Then run:

flutter pub get

🏗️ Supported Components #

Built-in Components #

🎯 Quick Start #

Basic Usage #

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

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    const xmlContent = '''
      <ChatResponse>
        <Message>Hello! Welcome to FlowXML 🚀</Message>
        <Card title="Getting Started" subtitle="Learn the basics">
          This card was generated from XML and rendered as a Flutter widget!
        </Card>
        <Image src="https://picsum.photos/300/200">
          Beautiful scenery
        </Image>
        <OptionSelector options="Yes,No,Maybe" title="Do you like it?">
          What do you think about FlowXML?
        </OptionSelector>
      </ChatResponse>
    ''';

    return FlowXML.renderer(
      xmlContent: xmlContent,
      onComponentInteraction: (action, data) {
        print('Component interaction: $action with data: $data');
      },
    );
  }
}

Real-time Streaming #

class StreamingExample extends StatefulWidget {
  @override
  _StreamingExampleState createState() => _StreamingExampleState();
}

class _StreamingExampleState extends State<StreamingExample> {
  late XmlStreamController _controller;
  List<ParsedComponent> _components = [];

  @override
  void initState() {
    super.initState();
    _controller = FlowXML.createStreamController();

    // Listen to parsed components
    _controller.componentsStream.listen((components) {
      setState(() {
        _components = components;
      });
    });

    _simulateAIResponse();
  }

  void _simulateAIResponse() async {
    _controller.startStreaming();

    final chunks = [
      '<ChatResponse>',
      '<Message>Analyzing your request...</Message>',
      '<Loader type="circular">Processing</Loader>',
      '<Card title="Analysis Complete">',
      'Based on your input, here are the results.',
      '</Card>',
      '<Button action="download">Download Report</Button>',
      '</ChatResponse>'
    ];

    for (final chunk in chunks) {
      await Future.delayed(Duration(milliseconds: 800));
      _controller.addChunk(chunk);
    }

    _controller.completeStreaming();
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children: _components.map((component) {
        return FlowXML.renderer(
          xmlContent: component.content,
          isStreaming: !component.isComplete,
          onComponentInteraction: (action, data) {
            // Handle user interactions
            ScaffoldMessenger.of(context).showSnackBar(
              SnackBar(content: Text('Action: $action')),
            );
          },
        );
      }).toList(),
    );
  }

  @override
  void dispose() {
    _controller.dispose();
    super.dispose();
  }
}

🎨 Customization #

Custom Components #

Create and register your own components:

class AlertComponent extends XmlComponent {
  const AlertComponent({super.key, required super.props});

  @override
  String get componentType => 'Alert';

  @override
  Widget build(BuildContext context) {
    final type = props.getAttribute('type', 'info');
    final title = props.getAttribute('title', 'Alert');

    return Container(
      padding: EdgeInsets.all(16),
      decoration: BoxDecoration(
        color: _getAlertColor(type),
        borderRadius: BorderRadius.circular(8),
        border: Border.all(color: Colors.grey.shade300),
      ),
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Text(title, style: TextStyle(fontWeight: FontWeight.bold)),
          SizedBox(height: 8),
          Text(props.content),
        ],
      ),
    );
  }

  Color _getAlertColor(String type) {
    switch (type) {
      case 'error': return Colors.red[50]!;
      case 'warning': return Colors.orange[50]!;
      case 'success': return Colors.green[50]!;
      default: return Colors.blue[50]!;
    }
  }
}

// Register the component
FlowXML.registerComponent('Alert', (props) => AlertComponent(props: props));

Now you can use it in XML:

<Alert type="success" title="Success!">
  Your operation completed successfully.
</Alert>

Custom Styling #

final customStyle = ComponentStyle(
  backgroundColor: Colors.grey[50],
  textColor: Colors.black87,
  fontSize: 16.0,
  padding: 20.0,
  margin: 12.0,
);

FlowXML.renderer(
  xmlContent: xmlContent,
  style: customStyle,
);

🔧 Advanced Features #

Component Registry Management #

// Check if component is registered
if (FlowXML.isComponentRegistered('CustomComponent')) {
  // Component is available
}

// Get registry statistics
final stats = FlowXML.registry.statistics;
print('Registered components: ${stats['registeredComponents']}');

// Register component aliases
FlowXML.registry.registerAlias('Img', 'Image');

Error Handling #

FlowXML.renderer(
  xmlContent: xmlContent,
  errorBuilder: (error) => Container(
    padding: EdgeInsets.all(16),
    child: Text('Error: $error', style: TextStyle(color: Colors.red)),
  ),
  loadingBuilder: () => CircularProgressIndicator(),
);

Component Interactions #

FlowXML.renderer(
  xmlContent: xmlContent,
  onComponentInteraction: (action, data) {
    switch (action) {
      case 'button_press':
        handleButtonPress(data['action'] as String);
        break;
      case 'option_select':
        handleOptionSelect(data['selected'] as List<String>);
        break;
      case 'copy':
        copyToClipboard(data['content'] as String);
        break;
    }
  },
);
