如何获取 Flutter 中的 AWS Cognito 用户组？

Question

I am building a mobile application with Flutter and AWS. I am using the AWS Cognito user pool to authenticate users in the app. There are types of users in my app, which is the type USER and ADMIN . The Admin users are in an ADMIN user group. After the user is authenticated, I want to get the user group's ADMIN to a different view.

How to get the user group in Flutter AWS?

Answer 1

I was able to get the user group after decoding the accessToken. The token contains cognito:groups attribute if the user inside a group

 AuthSession authSessions = await Amplify.Auth.fetchAuthSession( options: CognitoSessionOptions(getAWSCredentials: true));

    if(authSessions.isSignedIn) {
      final accessToken = (authSessions as CognitoAuthSession).userPoolTokens?.accessToken;
      print("identityId ==>  ${accessToken}");
    }
