v2.4.0

We are officially deprecating all persistent utility services (trackers and limiters) from the prf package. To keep prf focused purely on persistence (without embedded logic), all advanced time-based utilities are being migrated to two new dedicated packages:

Why this change?

• Improves modularity and keeps prf lightweight.
• Reduces dependencies for apps that only need persistence.
• Allows track and limit to evolve independently with focused updates.
• Removes ~300 extra tests and ~1,200 lines from the README, which had made the package heavy and harder to navigate.
• Frees up space to expand limit and track with more features and utilities while keeping prf clean, focused, and ~90% smaller in size.

✅ The APIs remain backward-compatible until v3.0 (2026) — just change your imports.

• limit package → https://pub.dev/packages/limit

  • PrfCooldown → Cooldown
  • PrfRateLimiter → RateLimiter

• track package → https://pub.dev/packages/track

  • PrfStreakTracker → StreakTracker
  • PrfPeriodicCounter → PeriodicCounter
  • PrfRolloverCounter → RolloverCounter
  • PrfActivityCounter → ActivityCounter
  • PrfHistory → HistoryTracker
  • Enums:
    • TrackerPeriod → TimePeriod
    • ActivitySpan → TimeSpan

flutter pub add track
flutter pub add limit

Deprecated in 2.4.0 (to be removed in v3.0.0 estimated 2026):

• Limit Services: PrfCooldown PrfRateLimiter
• Tracking Services: PrfStreakTracker PrfPeriodicCounter PrfRolloverCounter PrfActivityCounter PrfHistory
• Enums: TrackerPeriod ActivitySpan
• Service Interfaces: BaseCounterTracker BaseTracker

Everything related to the services. Nothing changed in prf itself.
