@Ansh-Rathod ill have to investigate, however it should theoretically work, have you tried?

yeah, i tried this, the major issue i think is it didn't added proper headers to request. every time headers was empty and response became 400 bad request.

Could you share the code? Will add a test case

@Ansh-Rathod how did you get this working? I can't find MultipartRequest anywhere in the edge library, and using the traditional http lib triggers

<ref *1> UnsupportedError {
  message: "Cannot create a client without dart:html or dart:io.",
  "$thrownJsError": <ref *2> Unsupported operation: Cannot create a client without dart:html or dart:io.

    dartException: [Circular *1],
    name: "",
    "$cachedTrace": _StackTrace { _exception: [Circular *2], _trace: null }
  }
}

and when trying with the provided fetch --

final mulitResponse = await edge.fetch(edge.Resource.request(httpRequest));

I see

The argument type 'MultipartRequest' can't be assigned to the parameter type 'Request'.dart[argument_type_not_assignable](https://dart.dev/diagnostics/argument_type_not_assignable)

nor does edge.fetch appear to support a StreamedResponse, which is what should be used in conjunction with MultipartRequest.

well, if you use runtimeclient with HTTP library.

well, if you use runtimeclient with HTTP library.

The problem is not with http, but the missing html/io libraries. Are you sure you got this working? Could you please share code? If it was not working for you please say so Invertase can prioritize this to be fixed.

I tried with

http.runWithClient(() => getResponse, () => EdgeHttpClient());

as well.

Any thoughts @Ehesp?
