send method
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<StreamedResponse> send(BaseRequest request) async {
request.headers.addAll(_headers);
if (request.method == "GET") {
return _networkFirst
? await _networkFirstRequest(request)
: await _cacheFirstRequest(request);
} else {
return await _client.send(request).timeout(_timeout);
}
}
