How can i observe the download percentage on (fun retrieveFromHttp)

[hishampro5]

I am trying to show progress bar to enhancement UX on my app while the book is downloading i am using suspend fun retrieveFromHttp for download the books so is there any way to achieve this or i need do some customization. i think this callBack is available on IOS ? so i am asking is this possible also on android.

for IOS :

private func fulfillIfNeeded(_ url: FileURL, progress: @escaping (Double) -> Void) async throws -> FileURL {
    guard lcp.canFulfill(url) else {
      return url
    }

    do {
      let pub = try await lcp.fulfill(url, progress: progress)
      return pub.localURL

    } catch {
      throw LibraryError.downloadFailed(error)
    }
  }

FYI : readium_version = '3.0.3'
