Constructors

Fsrs({List<double>? parameters})

Properties

hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.

w → List<double>
final

Methods

calculate({required FsrsState state, required FsrsRating rating, required double elapsedDays, double targetRetention = 0.9}) → FsrsResult
Schedule a card given its current state, the user's rating, and the number of elapsedDays since last review. targetRetention controls the desired recall probability (default 0.9).
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

migrateFromSm2({required double easinessFactor, required int intervalDays, required int repetitions}) → FsrsState
Approximate FSRS state from SM-2 parameters for cold-start migration.
retrievability(double elapsedDays, double stability) → double
Compute retrievability (probability of recall) at elapsedDays given current stability. Public so callers can estimate knowledge decay.
