Flutter Core SDK

A comprehensive Flutter SDK for video player analytics and event tracking, designed to provide detailed insights into video playback behavior and user engagement metrics.

Features

• Comprehensive Event Tracking: Monitor all video player events including play, pause, seeking, buffering, and more
• Real-time Analytics: Track view watch time, player state changes, and user engagement metrics
• Flexible Configuration: Customizable workspace IDs, beacon URLs, and custom data fields
• Lifecycle Management: Automatic app lifecycle handling and session management
• Cross-platform Support: Works seamlessly on both iOS and Android platforms
• Performance Optimized: Efficient event dispatching and state management
• Extensible Architecture: Easy to extend with custom events and data models

Installation

Add the following dependency to your pubspec.yaml:

dependencies:
  flutter_core_sdk: ^1.0.2

Then run:

flutter pub get

Quick Start

Here's a minimal example to get you started:

import 'package:fastpix_flutter_core_data/fastpix_flutter_core_data.dart';

void main() {
  // Configure the SDK
  final metrics = FastPixMetrics.builder()
    .setWorkSpaceId('your-workspace-id')
    .setBeaconUrl('https://your-beacon-url.com')
    .setViewerId('user-123')
    .build();

  // Track player events - only dispatch play event
  // SDK automatically handles viewBegin and playerReady internally
  metrics.dispatchEvent(PlayerEvent.play);
}

Usage / API Reference

Core Classes

FastPixMetrics

The main entry point for the SDK. Handles event dispatching and configuration management.

class FastPixMetrics {
  // Dispatch player events
  // Note: Only dispatch play event - SDK automatically handles viewBegin and playerReady
  Future<void> dispatchEvent(PlayerEvent event, {Map<String, String>? attributes});
  
  // Get current player observer
  PlayerObserver get playerObserver;
}

MetricsConfiguration

Configuration class for setting up the SDK with required parameters.

class MetricsConfiguration {
  final PlayerData? playerData;
  final String? workspaceId;
  final String? beaconUrl;
  final String? viewerId;
  final VideoData? videoData;
  final bool enableLogging;
  final List<CustomData>? customData;
}

PlayerEvent

Enumeration of all supported video player events:

• play - Video playback started (automatically triggers viewBegin and playerReady)
• pause - Video playback paused
• playing - Video is currently playing
• seeking - User is seeking to a new position
• seeked - Seek operation completed
• buffering - Video is buffering
• buffered - Buffering completed
• variantChanged - Video quality/bitrate changed
• viewBegin - Video view session started (handled automatically by SDK)
• viewCompleted - Video view session completed
• playerReady - Player is ready to play (handled automatically by SDK)
• ended - Video playback ended
• error - Player error occurred
• pulse - Periodic heartbeat event

Builder Pattern

The SDK uses a builder pattern for easy configuration:

final metrics = FastPixMetrics.builder()
  .setWorkSpaceId('workspace-123')
  .setBeaconUrl('https://analytics.example.com')
  .setViewerId('user-456')
  .setPlayerData(playerData)
  .setVideoData(videoData)
  .setCustomData(customDataList)
  .isEnableLogging(true)
  .build();

Configuration

Required Parameters

• workspaceId: Unique identifier for your workspace/application
• beaconUrl: Endpoint URL for sending analytics data
• viewerId: Unique identifier for the current user/viewer

Important Note

Automatic Event Handling: The SDK automatically manages viewBegin and playerReady events when you dispatch the play event. Developers only need to dispatch the play event - the SDK handles the rest internally for optimal analytics tracking.

Optional Parameters

• playerData: Information about the video player (name, version, etc.)
• videoData: Video metadata (title, duration, quality, etc.)
• customData: Additional custom fields for your analytics
• enableLogging: Enable/disable debug logging

Environment Setup

1. Workspace Configuration: Set up your analytics workspace and obtain the workspace ID
2. Beacon Endpoint: Configure your analytics server endpoint
3. User Identification: Implement a system to generate unique viewer IDs

Examples

Basic Video Player Integration

class VideoPlayerWidget extends StatefulWidget {
  @override
  _VideoPlayerWidgetState createState() => _VideoPlayerWidgetState();
}

class _VideoPlayerWidgetState extends State<VideoPlayerWidget> {
  late FastPixMetrics metrics;
  
  @override
  void initState() {
    super.initState();
    
    // Initialize SDK
    metrics = FastPixMetrics.builder()
      .setWorkSpaceId('video-app-123')
      .setBeaconUrl('https://analytics.videoapp.com')
      .setViewerId('user-${DateTime.now().millisecondsSinceEpoch}')
      .build();
      
    // Note: No need to dispatch playerReady or viewBegin events
    // SDK handles these automatically when play event is dispatched
  }
  
  void onPlay() {
    // Only dispatch play event - SDK automatically handles viewBegin and playerReady
    metrics.dispatchEvent(PlayerEvent.play);
  }
  
  void onPause() {
    metrics.dispatchEvent(PlayerEvent.pause);
  }
  
  void onSeek(Duration position) {
    metrics.dispatchEvent(PlayerEvent.seeking);
    // After seek completes
    metrics.dispatchEvent(PlayerEvent.seeked);
  }
}

Custom Data Integration

// Create custom data fields
final customData = [
  CustomData(value: 'movie'),
  CustomData(value: 'action'),
  CustomData(value: '2024'),
];

// Configure SDK with custom data
final metrics = FastPixMetrics.builder()
  .setWorkSpaceId('workspace-123')
  .setBeaconUrl('https://beacon.example.com')
  .setViewerId('user-789')
  .setCustomData(customData)
  .build();

Advanced Event Tracking

// Track events with additional attributes
await metrics.dispatchEvent(
  PlayerEvent.variantChanged,
  attributes: {
    'height': '1080',
    'width': '1920',
    'bitrate': '5000000',
    'frameRate': '30',
    'codecs': 'avc1.640028',
    'mimeType': 'video/mp4',
  },
);
