You're calling the method getCurrentNavigation too late. The navigation has finished.

You need call the getCurrentNavigation method inside of the constructor:

constructor(private router: Router) {
    this.name = this.router.getCurrentNavigation().extras.state.someData;
}

Or if you want to access the navigation in ngOnInit you can do following:

ngOnInit() {
    this.name = history.state.someData;
}
