ajinasokan / flutter_curl Goto Github PK

This is what I get as soon as I import the package into a project file. This happens even with the latest dependency version.

../../../../.pub-cache/hosted/pub.dev/flutter_curl-0.1.1/lib/src/ffi.dart:12:8: Error: Field 'messageType' cannot be nullable or have type 'Null', it must be int, double, Pointer, or a subtype of StructorUnion. int? messageType; ^ ../../../../.pub-cache/hosted/pub.dev/flutter_curl-0.1.1/lib/src/ffi.dart:14:27: Error: Field 'easyHandle' cannot be nullable or have type 'Null', it must be int, double, Pointer, or a subtype of StructorUnion. ffi.Pointer<_CURLEasy>? easyHandle; ^ ../../../../.pub-cache/hosted/pub.dev/flutter_curl-0.1.1/lib/src/ffi.dart:17:8: Error: Field 'result' cannot be nullable or have type 'Null', it must be int, double, Pointer, or a subtype of StructorUnion. int? result; ^

If you'd like to help, that'd be great.

But it's normal on Android, what can i do?

could you share an SOP on rebuilding Curl.framework from scratch

Hi,
I'm new to flutter_curl, but I use curl a lot, can you tell me how to use flutter_curl to retrive verbose info, just like get output from curl -v $url

On desktop, it says
Failed to load dynamic library '/home/meisme/AndroidStudioProjects/minebird/build/linux/x64/debug/bundle/lib/libcurl.so': /home/meisme/AndroidStudioProjects/minebird/build/linux/x64/debug/bundle/lib/libcurl.so: cannot open shared object file: No such file or directory
I know there's a .so file in Releases, but I'm unsure where to place it. Do I manually place the file every time I build?

Excpected goal:
I want to upload files to multipart API using these plugins:

1. shelf_multipart on the API side
2. this flutter_curl plugin on the mobile side

but it gives me "MimeMultipartException: Bad multipart ending", however it works perfectly executed in CMD as shown below

curl -H "Content-Type: multipart/mixed" -F id=2 -F [email protected] -F [email protected] -F [email protected] -F [email protected] -F [email protected] -F [email protected] -F [email protected] -F [email protected] http://127.0.0.1:8080/test_upload

HOW I can achive this using flutter_curl? or what is the solution to this problem?

here are some supporting attachments:

1. server side

Future<Response> upload(Request request) async {
    try {
      // final description = StringBuffer('Regular multipart request\n');

      int audioFileCount = 1;

      Map<String, String> data = {};

      await for (final part in request.parts) {
        String content = part.headers['content-disposition'];

        if (content.contains('name="id"')) {
          data.addAll({
            'id': await part.readString(),
          });
        } else if (content.contains('name="audio_$audioFileCount"')) {
          Uint8List file = await part.readBytes();

          data.addAll({
            'mfcc_$audioFileCount': extractMfcc(file)
                .toString(), // looks like --> mfcc_1: [[10.1209..], [10.1217..], ..]
          });

          audioFileCount++;
        }
      }

      print(data);

      if (audioFileCount != 9) {
        return Response.forbidden('Fields not filled perfectly.');
      }

      Map<String, dynamic> result = await model.updateMFCC(data);

      if (result['status']) {
        return Response.ok(json.encode({
          'status': true,
          'message': 'Complete processing.',
        }));
      } else {
        return Response.ok(json.encode({
          'status': false,
          'message': 'Processing failed.',
        }));
      }
    } on FormatException catch (e) {
      return Response.internalServerError(
          body: '!!EXCEPTION!!\n${e.toString()}\n${e.message.toString()}');
    } on Exception catch (e) {
      print(e
          .toString()); // Produced: "MimeMultipartException: Bad multipart ending"
      return Response.internalServerError(
          body: '!!EXCEPTION!!\n${e.toString()}');
    }
  }

2. mobile side

String path = 'test_upload';
APIMethod method = APIMethod.post;
Map<String, String>? parameters = {'id': '1'};
List<File> files = const [File('path/to/file.wav'), File('path/to/file.wav'), ...];
List<String> fields = const ['audio_1', 'audio_2', ...];

Client client = Client(
  verbose: true,
  interceptors: [
    // HTTPCaching(),
  ],
);

await client.init();

List<Multipart> multiparts = [];

parameters.forEach((key, value) {
  multiparts.add(Multipart(
    name: key,
    data: value,
  ));
});

if (files.isNotEmpty && fields.isNotEmpty) {
  if (files.length == fields.length) {
    for (var i = 0; i < files.length; i++) {
      multiparts.add(
        Multipart.file(
          name: fields[i],
          path: files[i].path,
          filename: "audio_$i.wav",
        ),
      );
    }
  } else {
    if (withPop) context.loaderOverlay.hide();

    showFlushbar(context, 'file and field count doesnt same.',
        color: Colors.red);

    return {
      'status': false,
      'message': 'file and field count doesnt same.',
    };
  }
}

final res = await client.send(Request(
  method: method == APIMethod.post ? "POST" : "GET",
  url: "http://$baseUrl/$path",
  headers: {"Content-Type": "multipart/mixed"},
  // body: RequestBody.raw(utf8.encode("hello world")),
  // body: RequestBody.string("hello world"),
  // body: RequestBody.form({"age": "10", "hello": "world"}),
  body: RequestBody.multipart(multiparts),
));

List<int> resBody = res.body;
Map<String, dynamic> resMap = res.headers;
String resText = res.text();

print('body: $resBody');
print('map: $resMap');
print('text: $resText');

It seems that bindings are pretty useful out of flutter context, and I cant find any usage of package:flutter outside of tests and example.

Would it be possible to distribute underlying bindings as separate package without flutter dependency to allow using it in dart server apps?

Direct local .aar file dependencies are not supported when building an AAR. The resulting AAR would be broken because the classes and Android resources from any local .aar file dependencies would not be packaged in the resulting AAR. Previous versions of the Android Gradle Plugin produce broken AARs in this case too (despite not throwing this error). The following direct local .aar file dependencies of the :flutter_curl project caused this error: E:\curl_demo_new\build\flutter_curl\libs\curl.aar.

I am getting this error while running the project. I have added plugin directly in pubspec.yaml.

curl can connect to proxy so this library should too.

Linux natively has curl. Why not support it?

Windows has a native wrapper for curl as well in powershell.
