recurrence_kit library

A standalone recurrence rule system — data models, computation engine, and a configurable picker UI widget.

Quick start

import 'package:recurrence_kit/recurrence_kit.dart';

// Create a rule
final rule = RecurrenceRule(
  type: RecurrenceType.weekly,
  daysOfWeek: [1, 3, 5],
);

// Check if a date matches
RecurrenceEngine.occursOnDate(rule, someDate, startDate);

// Full picker widget
RecurrencePicker(
  rule: rule,
  onChanged: (updated) => setState(() => _rule = updated),
  startDate: DateTime.now(),
)

What's included

• Models: RecurrenceRule, RecurrenceType, RecurrenceEndType — immutable data with JSON serialization.
• Engine: RecurrenceEngine — pure, stateless occurrence logic.
• Widget: RecurrencePicker — a configurable inline editor for building recurrence rules, themed via RecurrencePickerTheme.
