upload method

@override Future<AdapterResponse> upload(AdapterRequest request, { ProgressCallback? onProgress, })

Uploads data to the server.

This method uploads data (typically files) to the server. Progress can be tracked using the optional onProgress callback.

Parameters:

• request: The request configuration for the upload, including the data to upload
• onProgress: Optional callback to track upload progress

Returns a Future that completes with an AdapterResponse when the upload is complete.

Throws AdapterException if the upload fails.

Example:

final request = AdapterRequest(
  baseUrl: 'https://api.example.com',
  path: '/upload',
  method: HttpMethod.post,
  bodyParams: {'file': File('/path/to/file.jpg')},
);

await adapter.upload(
  request,
  onProgress: (count, total) {
    print('Uploaded: ${(count / total * 100).toStringAsFixed(1)}%');
  },
);

Implementation

@override
Future<AdapterResponse> upload(
  AdapterRequest request, {
  ProgressCallback? onProgress,
}) async {
  try {
    final options = _convertToOptions(request);
    final requestBody = _buildRequestBody(request);
    final dioCancelToken = _convertCancelToken(request.cancelToken);

    try {
      final response = await _dio.request(
        request.buildFullUrl(),
        data: requestBody,
        queryParameters: request.queryParams,
        options: options,
        cancelToken: dioCancelToken,
        onSendProgress: onProgress,
      );

      return _convertFromResponse(response, request);
    } finally {
      _cancelTokenMap.remove(request.cancelToken);
    }
  } on DioException catch (e) {
    throw _convertException(e);
  }
}
