requestToServer method

Future<ApiResponseModel> requestToServer({ required String requestUrl, required ApiRequestMethod requestMethod, Object? bodyParams, Map<String, String>? headers, })

requestUrl -> you need to pass API's url here as String requestMethod -> it is also String type, you just need to pass your API's method bodyParams -> sets the body of the request. It can be a String, a List or a Map<String, String>. If it's a String, it's encoded using encoding and used as the body of the request. The content-type of the request will default to "text/plain". If bodyParams is a List, it's used as a list of bytes for the body of the request. If bodyParams is a Map, it's encoded as form fields using encoding. The content-type of the request will be set to "application/x-www-form-urlencoded"; this cannot be overridden. headers -> it is Map<String, String> type, you need to pass headers because it helps you contain more information about the resource to be fetched, or about the client requesting the resource and also hold additional information about the response, like its location or about the server providing it.
