Class Configuration for exponential-backoff polling loops used throughout the SDK. 
class CrossmintPollingConfig
The delay between consecutive poll attempts grows exponentially from initialDelay up to maxDelay, with optional random jitter to prevent thundering-herd effects when many clients poll in parallel. The total number of attempts is capped at maxAttempts.

​
Constructors

​
CrossmintPollingConfig

const CrossmintPollingConfig({
  this.initialDelay = const Duration(seconds: 1),
  this.maxDelay = const Duration(seconds: 8),
  this.maxAttempts = 60,
  this.jitter = true,
  this.backoffFactor = 2.0,
})
Creates a polling configuration.

​
Properties

​
initialDelay

final Duration initialDelay
Delay before the first retry (doubles each attempt up to maxDelay).

​
maxDelay

final Duration maxDelay
Upper bound on the delay between attempts.

​
maxAttempts

final int maxAttempts
Maximum number of poll iterations before timing out.

​
jitter

final bool jitter
When true, each computed delay is multiplied by a random factor in the range [0.5, 1.0) to spread retries across time.

​
backoffFactor

final double backoffFactor
Multiplicative factor applied to the delay each iteration.

​
Methods

​
delayForAttempt

Duration delayForAttempt(int attempt, [Random? random])
Computes the delay for a given zero-based attempt index.
