Show drag and drop based on condition not working

[Aya Al Bakri]

In solution below I tried to hide uploader component based on condition. 

https://stackblitz.com/edit/angular-fsda2b-svvbkj?file=app.component.html,app.component.css,app.component.ts
when I upload the file I hide  uploader  component and display Remove button so we restrict uploading a new file (user must remove file before upload other file) after removing new file and display uploader component the drag and drop feature not working.

By setting the droparea in the created event of the uploader component instead of the ngAfterViewInit event, you can resolve the reported issue.
