Extract value of an element from object instance

Here is my code to get the current users phone number.

  Future<void> getCurrentUser() async {
    try {
      AuthUser user = await Amplify.Auth.getCurrentUser();
      print(user.signInDetails);
    } on AuthException catch (e) {
      safePrint('Error retrieving current user: ${e.message}');
    }
  }

The print statement above which extracts the values of the signInDetails array, does not allow me to go deeper one more level. Here is result if I just print the object instance -

CognitoSignInDetailsApiBased {
I/flutter (19338):   "signInType": "apiBased",
I/flutter (19338):   "username": "+14160000000",
I/flutter (19338):   "authFlowType": "USER_SRP_AUTH"
I/flutter (19338): }

How do I just get the value of username element above.

Solution

  • According to the docs you posted, AuthUser#signInDetails returns an instance of SignInDetails, documented here. It looks like there isn't an accessor username, but there is a toJson() method that returns a map. Given that, you should be able to print just the username value via print(user.signInDetails.toJson()['username'])
