AWS Amplify signedIn Variable is undefined

I am using the aws-amplify from this site I noticed on this site, this.signedIn is not used anywhere on this link. I am attempting to use is as an indicator true/false value as to if the user is signed in.

This is the code:

  constructor(public mediaObserver: MediaObserver, private amplifyService: AmplifyService ){
this.amplifyService.authStateChange$
.subscribe(authState => {
    this.signedIn = authState.state === 'signedIn';
  });
  console.log('This is from home constructor for signedIn boolean value ', this.signedIn)

this.signedIn is sent to the console window as : undefined

The AppComponent does not set an initial value for signedIn so by default it will be undefined:

export class AppComponent {
    signedIn: boolean;
    ...
}

Your console.log(...) is within the components constructor and so when the log call is hit - the value is still undefined.

You will still be able to refer to signedIn from within your template as the undefined value will resolve to false. Or you can be more explicit and initialize with signedIn: boolean = false.
