retryWithExponentialBackoff

fun <T> ERROR CLASS: Symbol not found for Flow<T>.retryWithExponentialBackoff(maxAttempts: Int, initialDelay: ERROR CLASS: Symbol not found for Duration, multiplier: Double = 2.0, retryOn: (Throwable) -> Boolean = { true }): ERROR CLASS: Symbol not found for Flow<T>(source)

Retries the flow when it fails, while increasing the delay between retries.

The wait time grows exponentially: initialDelay * multiplier^attempt.

The flow stops retrying after maxAttempts or if retryOn returns false.

Example:

flow {
    emit(fetchData())
}
.retryWithExponentialBackoff(
    maxAttempts = 5,
    initialDelay = 100.milliseconds,
    multiplier = 2.0
)
.collect { data ->
    println("Got $data")
}

In this example, if fetchData() fails, it will retry up to 5 times, waiting 100ms, 200ms, 400ms, 800ms, and 1600ms between tries.
