Utility for wrapping an asynchronous function in automatic retry logic with ability to cancel it.
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.
To use this plugin, add
cancelable_retry as a dependency in your pubspec.yaml file.
Create instance of
CancelableRetry and call
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();
If you want to cancel retries, just call
