1. pubspec.yaml

              dependencies:
                flutter:
                  sdk: flutter
                http: ^0.14.0

              

2. File Upload Functionality:

              import 'package:get/get.dart';
                  import 'package:http/http.dart' as http;

                  class FileUploadController extends GetxController {
                    Future<void> uploadFile(String filePath) async {
                      var url = 'YOUR_UPLOAD_URL'; // Replace with your server's upload URL

                      var request = http.MultipartRequest('POST', Uri.parse(url));
                      request.files.add(await http.MultipartFile.fromPath('file', filePath));

                      try {
                        var response = await request.send();
                        if (response.statusCode == 200) {
                          // File uploaded successfully
                          print('File uploaded');
                        } else {
                          // Handle error response
                          print('Error uploading file');
                        }
                      } catch (e) {
                        // Handle network and other errors
                        print('Error: $e');
                      }
                    }
                  }


                  

3. Use GetX Controller in Widget:

                  import 'package:flutter/material.dart';
                  import 'package:get/get.dart';
                  import 'file_upload_controller.dart';

                  class FileUploadPage extends StatelessWidget {
                    final FileUploadController _fileUploadController = Get.put(FileUploadController());

                    @override
                    Widget build(BuildContext context) {
                      return Scaffold(
                        appBar: AppBar(
                          title: Text('File Upload Example'),
                        ),
                        body: Center(
                          child: ElevatedButton(
                            onPressed: () async {
                              // Replace 'filePath' with the actual path of the file you want to upload
                              String filePath = '/path/to/your/file.ext';
                              await _fileUploadController.uploadFile(filePath);
                            },
                            child: Text('Upload File'),
                          ),
                        ),
                      );
                    }
                  }
