HttpLink class

A simple HttpLink implementation.

To use non-standard Request and Response shapes you can override serializeRequest, parseResponse, parseError and parseLocation.

To customize the request headers you can pass a custom http.Client to the constructor.

HttpLink(String uri, {Map<String, String> defaultHeaders = const {}, bool useGETForQueries = false, Client? httpClient, RequestSerializer serializer = const RequestSerializer(), ResponseParser parser = const ResponseParser(), HttpResponseDecoder httpResponseDecoder = _defaultHttpResponseDecode, bool followRedirects = false}): Construct the Link

defaultHeaders → Map<String, String>: Default HTTP headers
final
followRedirects → bool: final
hashCode → int: The hash code for this object.
no setterinherited
httpResponseDecoder ↔ HttpResponseDecoder: A function that decodes the incoming http response to Map<String, dynamic>, the decoded map will be then passes to the RequestSerializer. It is recommended for performance to decode the response using compute function.
getter/setter pair
parser → ResponseParser: Parser used to parse response
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
serializer → RequestSerializer: Serializer used to serialize request
final
uri → Uri: Endpoint of the GraphQL service
final
useGETForQueries → bool: set to true to use the HTTP GET method for queries (but not for mutations)
final

concat(Link next) → Link: Adds next after this link

dispose() → Future<void>: Closes the underlining http.Client
override
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
request(Request request, [NextLink? forward]) → Stream<Response>: A function called when a request reaches this Link
override
route(LinkRouter route) → Link: Route requests after this link

split(bool test(Request request), Link left, [Link right = const PassthroughLink()]) → Link: Split requests after this link

toString() → String: A string representation of this object.
