Ok yes I understand now!
That said, I've checked in my work project, 90% of ViewChild are one-lined haha. But we're using Angular 6 at this time.
That means that if I want to upgrade from Angular 6 to 8, I will have to "rewrite" all my ViewChild declarations ?

Basically yes.
However the CLI will help you as much as it can. The ng upgrade command will, for each ViewChild in your code base, try to detect if it is used statically or dynamically and then add the static parameter itself. If it cannot be determined by the static analysis of the CLI, a TODO comment will be added above each ViewChild to update.

Indeed they handle this case in the upgrade process :) Thanks for explanation!
