Need to get the translated value in app component using ngx-translate

[gesberk]

<a-label [keyValue] = "'key' | translate" />

This is the line in app.component.html. The value is loading but it takes time to assign the translate value to keyValue that is why i can't get the value inside my ts file.

@Input() keyValue : string;

console.log(this.keyValue); -----> undefined

Lazy loading....

please give any solution.
