Description:

cancelable retry

cancelable_retry #



Utility for wrapping an asynchronous function in automatic retry logic with ability to cancel it.
Features #
Allows to automatically retry request on some condition. Retry logic implemented with exponential back-off, useful when making requests over network.
If you don't need to continue retry - you can cancel retry. In such case last result will be returned.
Getting started #
To use this plugin, add cancelable_retry as a dependency in your pubspec.yaml file.
Usage #
Create instance of CancelableRetry and call run():
import 'package:cancelable_retry/cancelable_retry.dart';

final request = CancelableRetry(
// Provide request function
() => doSomeRequest(),
// Set conditions for retry
retryIf: (result) => result == "retry",
// Optional:
// - Define max retry attempts
maxAttempts: 8,
// - Define max delay between retries
maxDelay: const Duration(seconds: 30),
// - Tune delay between retries
delayFactor: const Duration(milliseconds: 200),
randomizationFactor: 0.25,
);

// Run request
final res = await request.run();
