Flutter simultaneous images upload

Question

I need to upload a list of images into a storage, but I don't want to upload and await for every single image after the other, because it takes quite some time. I would like to upload them simultaneously, like in different threads. There is a way to do achieve multithreading with standard dart async? Or should I use Isolates? Do you have some sample code?

Solution

You can use them in a single future

final results = await Future.wait([
  uploadFunction(image1)
  uploadFunction(image2)

]);

you can start uploading all images without waiting for the previous one to complete await will be returned once both uploads are completed

It seems that this library just allows me to queue futures and execute them one after the other, it does not execute them simultaneously. Am I wrong?

Yes you are right but for the image uploading, i suggest you to use it to avoid await.

Sorry but I don't think this can help me. I need to await for the upload, but I want to speed up the process by uploading simultaneously using different threads.

Okay, Keep growing !
