Quick Start

1. Initialize AddStream

In your main.dart, initialize AddStream before running your app:

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

void main() {
  // Initialize AddStream
  AddStreamGlobal.initialize(
    AddStreamConfig(
      apiUrl: 'https://your-api-url.com',
      apiKey: 'your-api-key-here',
    ),
  );
  
  runApp(MyApp());
}

2. Use the Widget

Add the AddStreamWidget anywhere in your app:

AddStreamWidget(
  zoneId: 'your-zone-id',
  width: 320,
  height: 50,
  margin: const EdgeInsets.all(16),
  borderRadius: 12,
  onAdLoaded: () => print('Ad loaded!'),
  onAdClicked: () => print('Ad clicked!'),
  onAdFailed: (error) => print('Error: $error'),
)

Usage Examples

Basic Banner Ad

class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: Text('My App')),
      body: Column(
        children: [
          Expanded(
            child: Center(child: Text('Your content here')),
          ),
          // Banner ad at the bottom
          AddStreamWidget(
            zoneId: '123',
            width: 320,
            height: 50,
          ),
        ],
      ),
    );
  }
}

Custom Loading & Error Widgets

AddStreamWidget(
  zoneId: '123',
  width: 300,
  height: 250,
  loadingWidget: Center(
    child: CircularProgressIndicator(),
  ),
  errorWidget: Container(
    padding: EdgeInsets.all(16),
    child: Text('Ad not available'),
  ),
  onAdLoaded: () {
    print('Ad successfully loaded');
  },
  onAdFailed: (error) {
    print('Failed to load ad: $error');
  },
)

With Callbacks

AddStreamWidget(
  zoneId: '123',
  width: 320,
  height: 100,
  onAdLoaded: () {
    // Track analytics
    analytics.logEvent('ad_loaded');
  },
  onAdClicked: () {
    // Track click
    analytics.logEvent('ad_clicked');
  },
  onAdFailed: (error) {
    // Handle error
    if (error is AddStreamException) {
      showErrorDialog(error.message);
    }
  },
)

API Reference

  ),
);

AddStreamException

Custom exception class for AddStream errors.

Error Handling

The package handles errors gracefully and provides multiple ways to handle them:

// Option 1: Using callback
AddStreamWidget(
  zoneId: '123',
  onAdFailed: (error) {
    if (error is AddStreamException) {
      print('AddStream error: ${error.message}');
    }
  },
)

// Option 2: Try-catch (for initialization)
try {
  AddStreamGlobal.initialize(config);
} on AddStreamException catch (e) {
  print('Failed to initialize: ${e.message}');
}

Common Issues

Widget not showing

Make sure you've initialized AddStream:

AddStreamGlobal.initialize(AddStreamConfig(apiUrl: '...', apiKey: '...'));

"AddStream not initialized" error

Call AddStreamGlobal.initialize() before using any widgets, typically in your main() function.

No ad appearing

This is normal when there's no ad inventory for your zone. The widget will show the errorWidget or hide itself.
