How to track upload progress?

This would be nice, any word on this.

Currently the http package is used for server communication and as far as I know, there is now way to track the uploading progress using this library.

In order to track the upload of files, we might have to switch to dio.

@phillwiggins Do you think we should do this? As the whole SDK uses the ParseHTTPClient (I think), this might actually be possible without to much changes.

[phillwiggins]

It does sound like a large change, however, I think you might be right. Except for websockets, I think the entire project depends on ParseHTTPClient which could be swapped out? It's definitely worth a try if you think that's the best option?

I have created a branch that uses dio, currently it seems to work, but I will do further testing.

When using it with a heavy app, web freezes sometimes. I think it is related to this.

Hi!
Any plans to do a PR with dio package? It may be so useful in android/ios.
Greetings!

The problem is, that at least my test app freezes, using the branch above.
@phillwiggins Do you think It would be an idea to leave everything as it is and just add dio for uploading a file (provinging an additional funktion like uploadWithProgress that uses the dio package)?
An other idea would be to create a parse_server_sdk_extension package, that adds some extra functionality, only some users need. (Personaly I am already using kind of such an approach for my application.)

I have created a branch that adds the option of getting the upload progress of a file.

This is only tested on Android. Further testing is appreciated.
Example:

file.upload(progressCallback: (int count, int total) => print("$count of $total"));

I am still not sure if I will create a PR with this change, as I think, using two network libraries is not ideal.

I tried to reproduce this freezes and where not able to do so.
Maybe it has been a bug in flutters beta channel.

I have added the progressCallback to the dio branch.
Testing is highly appreciated. Pleas notify me, if you encounter any ui freezes or other problems.

If we would change the whole SDK to use dio (PR this branch) we could even add send and receive progress indications to the ParseObject().save() and QueryBuilder().query(). In normal use cases, this might not be used that often, but it might be handy, if many objects are fetched in a single query.
