I have a component which takes a boolean value as @Input. I am controlling a div using ngIf with this value(to show/hide). Now, when I pass value true or false in both cases, the UI shows the div, whereas when not giving anything, it does not. Am I missing something here?

Index.html

<abc-comp x="1" y="64" showviewmore="true"></abc-comp>

abc-comp.ts

  @Input() x = '';
  @Input() y = '';
  @Input() showviewmore : boolean;

abc-comp.html

  <div class="col-xs-4" *ngIf="showviewmore">
      //Some Content and tags
  </div>

Also, I am trying to reassign the value of showviewmore variable in the ngOnInit() method but it never enters the if statement

  ngOnInit(): void {
   if(!this.showviewmore){
     this.showviewmore = newValue;
   }

Can anyone please help me? Thanks in advance
