Frequency-capping core — pure, platform-free logic. Dart port of Android's FrequencyEvaluator, sharing the identical golden matrix across platforms. now and sessionId are injected so the logic is fully deterministic and unit-testable.

Static Methods

evaluate(FrequencyPolicy policy, FrequencyState? state, int now, String? sessionId) → FrequencyEvalResult

Pure eligibility check. Blocks if ANY active constraint is exceeded: permanent stop, lifetime total, or the current window.

recordShow(FrequencyPolicy policy, FrequencyState? state, int now, String? sessionId) → FrequencyState

Record one show on "Digia Experience Viewed". Bumps the lifetime total and the window count, re-anchoring the window when it has rolled over.

recordStop(FrequencyState? state, int now) → FrequencyState

Permanently stop the campaign on "Digia Experience Completed" when the policy opted into stopOn. Idempotent: the first stop timestamp wins.
