Login Flow

Basics

The main class used is the Id4meLogon class. The package also contains many more classes that are used by the Id4meLogon class. View the Example for a detailed example on how to use the Id4meLogon.

Create login service

The first step in the login flow is to create an instance of the login service class Id4meLogon with the necessery properties and Id4meClaimsParameters.

Map<String, dynamic> properties = {
    Id4meConstants.KEY_CLIENT_NAME: "ID4me Login Demo",
    Id4meConstants.KEY_LOGO_URI: "https://domain.com/favicon.png",
    Id4meConstants.KEY_REDIRECT_URI: "https://domain.com/redirect"
};

Id4meClaimsParameters claimsParameters = new Id4meClaimsParameters();
  claimsParameters.entries.add(Entry("email", true, "Needed to create the profile"));

Id4meLogon logon = new Id4meLogon(properties: properties, claimsParameters: claimsParameters);

Create Session Data

The next step is to create the session data, that is needed throughout the hole login process. It fetches for example the DNS data and identity authority data.

Id4meSessionData sessionData = await logon.createSessionData(domain, true);

Build Authorization Url

The data from the DNS can now be used to create an authentication url to which the user is routed.

String authorizationURL = logon.buildAuthorizationUrl(sessionData);

Authenticate

After the user has been redirected by the Identity Authority, the code, given as a query parameter in the redirect url, can be used to authorize with the Identity Agent.

The redirect url could look like this : https://domain.com/redirect?code=DKYPkDfkH0cLw3_NmS6IGQ.BPA4gUtfLh0gljqQ3wJNVw&state=authorize

await logon.authenticate(sessionData, code);

Fetch UserInfo

After successful authorization, the requested user data can be queried.

Map<String, dynamic> info = await logon.fetchUserinfo(sessionData);
