Properties

baseDelay → Duration
The base delay (multiplied by 2^attempt).
final
hashCode → int
The hash code for this object.
no setterinherited
maxDelay → Duration
Upper bound — the computed delay is capped at this value.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
withJitter → bool
When true, a random jitter of ±25 % is applied to reduce thundering herd effects.
final
