+# curl_parser
+
+A Dart package that provides a `Curl` class for parsing and formatting cURL commands.
+
+## Usage
+
+1. Add the package to your `pubspec.yaml` file
+
+2. Use the package:
+
+```dart
+import 'package:curl_converter/curl_converter.dart';
+
+void main() {
+  // Parse a cURL command
+  final curlString = 'curl -X GET https://www.example.com/';
+  final curl = Curl.parse(curlString);
+
+  // Access parsed data
+  print(curl.method); // GET
+  print(curl.uri); // https://www.example.com/
+
+  // Format Curl object to a cURL command
+  final formattedCurlString = curl.toCurlString();
+  print(formattedCurlString); // curl -X GET https://www.example.com/
+}
+```
+
+See [test](https://github.com/foss42/curl_converter/tree/main/test) folder for more example usages.
+
+## Features
+
+- Parse a cURL command into a `Curl` class instance.
+- Format a `Curl` object back into a cURL command.
+- Supports various options such as request method, headers, data, cookies, user-agent, and more.
