httpRequest method

Future<SmartResponse> httpRequest({ required String method, required String url, Object? body, Map<String, String>? headers, String? encoding, required List<String> certificateHashes, required PinningMethod pinningMethod, })

Sends an HTTP request with certificate pinning support.

This method performs an HTTP request using the specified method and url, with optional body, headers, and encoding. The request is secured using the provided certificateHashes for certificate pinning.

Supports backup pins: provide multiple hashes so the connection succeeds if ANY hash matches. This prevents app downtime during certificate rotation.

Returns a SmartResponse object containing the result or error details.
