Flutter Workmanager Example

Complete working demo showing all Flutter Workmanager features and task types.

Features Demonstrated

• One-off tasks: Immediate background execution
• Periodic tasks: Scheduled recurring background work
• Processing tasks: Long-running iOS background tasks
• Task constraints: Network, battery, and device state requirements
• Debug notifications: Visual feedback when tasks execute
• Error handling: Proper task success/failure/retry logic
• Platform differences: Android vs iOS background execution

Quick Start

1. Clone and run:

   git clone https://github.com/fluttercommunity/flutter_workmanager.git
   cd flutter_workmanager/example
   flutter run

2. Platform setup:

   • Android: Works immediately ✅
   • iOS: Follow the iOS setup in ios/Runner/AppDelegate.swift and ios/Runner/Info.plist

3. Test background tasks:

   • Tap buttons to schedule different task types
   • Put app in background to see tasks execute
   • Check debug notifications to verify execution

Example Tasks

The demo includes practical examples:

• Simulated API sync: Fetches data and stores locally
• File cleanup: Removes old cached files
• Periodic maintenance: Regular app maintenance tasks
• Long processing: iOS-specific long-running tasks

Key Files

• lib/main.dart - Main app with task scheduling UI
• lib/callback_dispatcher.dart - Background task execution logic
• ios/Runner/AppDelegate.swift - iOS background task registration
• ios/Runner/Info.plist - iOS background modes configuration

Testing Background Tasks

Android:

• Tasks run reliably in background
• Enable debug mode to see notifications
• Use adb shell dumpsys jobscheduler to inspect scheduled tasks

iOS:

• Test on physical device (not simulator)
• Enable Background App Refresh in Settings
• Use Xcode debugger commands to trigger tasks immediately
