How to return the changes or return the value to parent after modal close in angular

Here's the code:

parent.ts

newInputName = '';
  inputName = '';
  addName = false;

constructor() {
private modal: NzModalService) { }

ngOnInit() {

    this.modal.afterAllClose.subscribe(md => {
      console.log(this.addArea)
    });
  }
 addItem(): void {
    this.inputName = this.name;
    this.newInputName = '';
    this.addName = true;
  }

parent.html

 <div class="modal-body">
        <label class="pb-2">Name</label>
        <input nz-input class="mr-2" [(ngModel)]="newInputName" placeholder="Type name...">
      </div>
    
      <nz-divider></nz-divider>
      <section class="form-footer" nz-row>
        <div nz-col>
          <button class="mr-1" nz-button nzType="primary" type="button" (click)="addItem()"
            [disabled]="newInputName.length <= 0">Add Name</button>
          <button nz-button class="btn-secondary" type="button" (click)="modalRef.close()"
            [textContent]="'Cancel' | translate"></button>
        </div>
      </section>

child.ts

  @Input() addName: boolean;
    editLayout(shopFloor?: any, lines?: any) {
    this.modalRef = this.modal.create({
      ......
    .....
    .....
    .......
    .......
    });

    this.modal.afterAllClose.subscribe((x: any) => {
      this.addName = false;
    });
  }

What I'm trying to do here is after submitted, the modal will be closed then the value addArea will be changed to false if the value of addName is true.

cause I'm having trouble when I try to save/submit the value still true when I try to change the value of addArea to true.

I also tried to do like this:

parent.html

<app-child [addNewName]="addName"></app-child>

child.ts

 @Input() addName: boolean;
 @Output()
  addNameChange = new EventEmitter<boolean>();

 @Input() addName: boolean;
        editLayout(shopFloor?: any, lines?: any) {
        this.modalRef = this.modal.create({
          ......
        .....
        .....
        .......
        .......
        });
    
        this.modal.afterAllClose.subscribe((x: any) => {
          this.addNameChange.emit(!this.addName);
        });
      }

But still it doesn't work.
