Can't upload on web, "MultipartFile is only supported where dart:io is available."

[esDotDev]

On Flutter Web, I'm calling cloudStorage.multiUpload and getting:

Error: Unsupported operation: MultipartFile is only supported where dart:io is available.
    at Object.throw_ [as throw] (http://localhost:52896/dart_sdk.js:5342:11)

Is this expected? Seems like this might be an issue in Dio, so not sure exactly where to log it.

Created an issue here: cfug/dio#1067

This might be a local workaround you could do?

@esDotDev I'm looking into this now. There was an initial plan to switch to https://pub.dev/packages/http instead of Dio

Update:

I was able to get it to work on web this way:

try {
  final res = await cloudinary.uploadFile(
    CloudinaryFile.fromByteData(
      ByteData.sublistView(
        await _pickedFile.readAsBytes(),
      ),
      identifier: _pickedFile.path.split('/').last,
    ),
  );
  print(res);
} catch (e, s) {
  print(e);
  print(s);
}

Amazing, thanks!

@esDotDev I have published a new version 0.7.0

• It now uses http instead of Dio
• Your initial code should also work on web, you don't have to use the code example I provided above.
