CarpService class

Provide access to a CARP web service endpoint.

The (current) assumption is that each Flutter app (using this library) will only connect to one CARP web service backend. Therefore a CarpService is a singleton and can be used like:

  CarpService().configure(myApp);
  CarpUser user = await CarpService()
    .authenticate(username: "user@dtu.dk", password: "password");

Constructors

CarpService()
Returns the singleton default instance of the CarpService. Before this instance can be used, it must be configured using the configure method.
factory
CarpService.instance()

Methods

authenticate() → Future<CarpUser>
Authenticate to this CARP service using a BuildContext, that opens the authentication page of the Identity Server using a secure web view from the OS.
authenticateWithDialog() → Future<CarpUser>
authenticateWithRefreshToken(String refreshToken) → Future<CarpUser>
authenticateWithToken({required CarpUser user, required OAuthToken token}) → CarpUser
Authenticate to this CARP Service using a OAuthToken access token and a CarpUser. This method is typically used to re-authenticate a user based on a previously granted access token, for example when the app is restarted.
authenticateWithUsernamePassword({required String username, required String password}) → Future<CarpUser>
Authenticate to this CARP service using a username and password.
authenticateWithUsernamePasswordNoContext({required String username, required String password}) → Future<CarpUser>
Authenticate to this CARP service using a username and password.
collection(String path) → CollectionReference
Gets a CollectionReference for the specified path.
configure(CarpApp app) → void
Configure the this instance of a Carp Service.
inherited
configureFrom(CarpBaseService service) → void
Configure from another service which has already been configured and potentially authenticated.
inherited
convertToTokenResponse(Map<String, dynamic> json) → TokenResponse
createConsentDocument(Map<String, dynamic> document) → Future<ConsentDocument>
Create a new (signed) consent document for this user. Returns the created ConsentDocument if the document is uploaded correctly.
document(String path) → DocumentReference
Gets a DocumentReference for the specified path.
documentById(int id) → DocumentReference
Gets a DocumentReference for the specified unique id.
documents() → Future<List<DocumentSnapshot>>
Get all documents for this study.
documentsByQuery(String query) → Future<List<DocumentSnapshot>>
Get a list documents based on a query.
getAllFiles() → Future<List<CarpFileResponse>>
Get all file objects in the study.
getConsentDocument(int id) → Future<ConsentDocument>
Get a previously uploaded (signed) ConsentDocument based on its id.
getCurrentUserProfile(TokenResponse response) → CarpUser
Gets the CARP profile of the current user from the JWT token
getDataPointReference() → DataPointReference
Creates a new DataPointReference initialized at the current CarpService storage location.
getFileStorageReference([int id = -1]) → FileStorageReference
Get a FileStorageReference that reference a file at the current CarpService storage location. id can be omitted if a local file is not uploaded yet.
getFileStorageReferenceByName(String name) → Future<FileStorageReference?>
Get a FileStorageReference that reference a file with the original name name at the current CarpService storage location.
logout() → Future<void>
Log out of this CARP service using a BuildContext, that opens a web view to clear cookies and end the sesion on the Identity Server.
logoutNoContext() → Future<void>
Logs out of this CarpService, by clearing the current user.
nonNullAble<T>(T? argument) → T
Makes sure that the CarpApp or CarpUser is configured, by throwing a CarpServiceException if they are null. Otherwise, returns the non-null value.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
queryFiles([String? query]) → Future<List<CarpFileResponse>>
Returns file objects in the study based on a query.
refresh() → Future<CarpUser>
Get a new access token for the current user based on the previously granted refresh token, using the Identity Server discovery URL.
refreshNoContext() → Future<CarpUser>
Get a new access token for the current user based on the previously granted refresh token, using the Identity Server discovery URL. Need to have run any of the authenticate functions first.
sendForgottenPasswordEmail() → Future<String>
toString() → String
A string representation of this object.
