send method

@override Future<StreamedResponse> send(BaseRequest request)

Sends an HTTP request and asynchronously returns the response.

Implementers should call BaseRequest.finalize to get the body of the request as a ByteStream. They shouldn't make any assumptions about the state of the stream; it could have data written to it asynchronously at a later point, or it could already be closed when it's returned. Any internal HTTP errors should be wrapped as ClientExceptions.

Implementation

@override
Future<http.StreamedResponse> send(http.BaseRequest request) async {
  final requestCreatedAt = DateTime.now().millisecondsSinceEpoch;
  final requestDateTime = DateTime.now();

  // Intercept and modify the request
  _onRequest(request);

  try {
    // Send the request
    final response = await httpClient.send(request);

    // Calculate request duration
    final now = DateTime.now().millisecondsSinceEpoch;
    final duration = (now - requestCreatedAt) / 1000.0;

    // Intercept and process the response
    _onResponse(request, response, requestDateTime, duration);

    return response;
  } catch (error, stackTrace) {
    // Calculate request duration
    final now = DateTime.now().millisecondsSinceEpoch;
    final duration = (now - requestCreatedAt) / 1000.0;

    // Intercept and handle errors
    _onError(request, error, stackTrace, requestDateTime, duration);
    rethrow; // Re-throw the error after handling it
  }
}
