🐛 Bug Report:Flutter web app, createFile() not uploading the whole file

[DobreRadu]

👟 Reproduction steps

I am using flutter_dropzone: ^3.0.5 to load the file,in onDrop: (dynamic ev) I added

  List<int> resultValue = [];
  await for (List<int> lista in controller.getFileStream(ev)) {
                                    resultValue = resultValue + lista;
                                  }

to create to create a List of the file.Using the createFile from appwrite sdk loads the image on the server(bigger than 5MB),it displays the actual size but when downloading it gives me part of the image(I estimate 5MB of data because of the test I did,where an image of 6Mb was not showing like 1/6 of the bottom part) and opening in New Window gives me a part of image then a link.

Future<File> result = storage.createFile(
                                    bucketId: '62fb5a75577eb6912acd',
                                    fileId: 'unique()',
                                    file: InputFile(
                                        filename: '${ev.name}',
                                        bytes: resultValue),
                                  );

Don't believe is from the flutter_dropzone,it works as it gives me the image as List,it actually loads all the bytes needed. Flutter doctor output:

I also tried to upload a file using the playground-for-flutter, but the uploaded file seemed to be invalid after downloading it again.

I also tried to upload a file using the playground-for-flutter, but the uploaded file seemed to be invalid after downloading it again.

Yes upload works in flutter,gives no error,but downloading it from server or displaying in the 'New Window' option doesn't work.

@DobreRadu I got it working without issues, here's the code I'm using https://github.com/appwrite/playground-for-flutter/tree/feat-upgrade-latest

Let me know if this works. (I'm using getFileData instead of getFileStream) to get the file bytes.

[DobreRadu]

I will try soon,thanks.

Tried using getFileData,still doesn't work. Future<File> result = storage.createFile( bucketId: dotenv.env['APPWRITE_BUCKET'] ?? '', fileId: 'unique()', file: InputFile( filename: '${ev.name}', bytes: await dropFileController .getFileData(ev)), );

[stnguyen90]

@DobreRadu, would you be able to provide the original file you're trying to upload?

Did it work ?

[stnguyen90]

@DobreRadu, I was able to reproduce, but @lohanidamodar will need to test to see if he can reproduce.

[DobreRadu]

Oh ok,thanks.

[grisoftumut]

BTW how you can upload big size of files? I can't any upload if the size bigger than 5mb. I don't understand the content-range details with dart

[stnguyen90]

@grisoftumut, thanks for your question, but please either create a new issue or join us on Discord. It can be confusing to talk about different topics in one issue.

[lohanidamodar]

@DobreRadu can you test from this branch? https://github.com/appwrite/sdk-for-flutter/tree/fix-flutter-web-chunked-upload

[DobreRadu]

You mean updating to appwrite 8.1.0?

[lohanidamodar]

@DobreRadu I mean using it from fix-flutter-web-chunked-upload branch on of the SDK

[DobreRadu]

Hello,tested with the appwrite 1.0 and sdk 8.1.0, it's working,thanks!

[DobreRadu]

Actually not,the photo given in this thread is still not working...it's giving me an URL. I tested with a 10mb photo and is working.

Are you sure? Because I ran multiple successful tests with this photo itself and other files as well, and the issue was mis-calculation which was resolved.

[DobreRadu]

Yes I am sure,maybe I use a different version or something then...Thanks for the help !
