Better ngClass typings #39280
Description
🐞 bug report
Affected Package
@angular/common.
Is this a regression?
In ng < 9, the type was any so it worked.
Description
Actually we can't pass readonly arrays or readonly sets with strictTemplates enabled, because the current types don't support it.
Another thing that is really trivial is that we can't use right now it with | async, as it could return null | undefined and it's also not supported.
