Vaadin Flow 8.0.0.alpha2

Breaking Changes:

⧉ Generate nullable TS types for Java types by default. PR:10754. Ticket:8849

Given a Java class as

public class Contact {
     private String name = "";
    private Company company;
}

the generated TypeScipt properties would be nullable by default, like

 export default interface Contact {
     company?: Company;
     name?: string;
 }

instead of non-nullable by default, as in previous versions

export default interface Contact {
    company: Company;
    name: string;
}
