Event Scheduler #

A powerful Flutter package that provides flexible event scheduling capabilities based on time or count triggers, with support for recurring events.

Features #

• ⏰ Time-based Triggers: Schedule events to occur at specific times or intervals
• 🔢 Count-based Triggers: Trigger events after a specific number of occurrences
• 🔄 Recurring Events: Support for both time-based and count-based recurrence
• ⚡ Customizable Intervals: Set custom intervals for recurring events
• 🎯 Maximum Recurrence Limits: Limit how many times an event can recur
• 📅 End Time Support: Set when events should stop recurring
• 🔔 State Management: Track event states and get notified of changes
• 🏗️ Builder Pattern: Easy configuration using a fluent interface

Getting started #

Add this to your package's pubspec.yaml file:

dependencies:
  event_scheduler: ^1.0.0

Usage #

Time-based Trigger #

EventSchedulerBuilder()
  .setEventKey('my_time_event')
  .setTriggerType(TriggerType.time)
  .setTriggerTime(DateTime.now().add(Duration(minutes: 5)))
  .setRecurrenceInterval(Duration(minutes: 30))
  .setOnEvent(() {
    print('Event triggered!');
  })
  .build();

Count-based Trigger #

EventSchedulerBuilder()
  .setEventKey('my_count_event')
  .setTriggerType(TriggerType.count)
  .setTriggerCount(5)
  .setOnEvent(() {
    print('Event triggered after 5 occurrences!');
  })
  .build();

// Track the event
SchedulerCore.track('my_count_event');

Hybrid Trigger with Recurrence #

EventSchedulerBuilder()
  .setEventKey('my_hybrid_event')
  .setTriggerType(TriggerType.time)
  .setTriggerTime(DateTime.now().add(Duration(minutes: 5)))
  .setRecurrenceType(RecurrenceType.count)
  .setRecurrenceCount(3)
  .setMaxRecurrences(5)
  .setOnEvent(() {
    print('Initial event triggered!');
  })
  .setRecurrenceOnEvent(() {
    print('Recurrence event triggered!');
  })
  .build();

Detailed Features #

Trigger Types #

• Time-based: Events trigger at specific times or intervals
• Count-based: Events trigger after a specific number of occurrences
• Hybrid: Combine both time and count-based triggers

Recurrence Types #

• None: Event triggers only once
• Time: Event recurs at specific time intervals
• Count: Event recurs after specific count intervals

Customization Options #

• Event Key: Unique identifier for each event
• Trigger Time: When time-based events should trigger
• Trigger Count: How many occurrences needed for count-based events
• Recurrence Interval: Time between recurring events
• Recurrence Count: Number of occurrences between recurrences
• Max Recurrences: Maximum number of times an event can recur
• End Time: When the event should stop recurring
• Callbacks: Custom handlers for events and state changes

Example Applications #

The package includes several example applications demonstrating different use cases:

• Basic time-based scheduling
• Count-based event tracking
• Recurring event management
• State management integration
• Builder pattern usage
