Migrating from vue-class-component

[nseb]

Hello ,
with vue-class-component, it's works :
@ComponentBase({
name: 'UMBaseComponent'
})
export default class UMBaseComponent extends Vue {
$q: QVueGlobals = useQuasar();
quasar : QVueGlobals = useQuasar();
....

@component({
name: 'LoginAvatar',
components: {Avatar, AccountPanel, Languages, Notifications, FollowedDriversPanel}
})
export default class LoginAvatar extends mixins(UMBaseComponent, AuthComponent) {
darkMode = this.quasar.dark.isActive;
...

with vue-facing-decorator , there is an error ; this.quasar is undefined , I know I can change the code , but I would like understand.

Use @Setup

@Component({
name: 'LoginAvatar',
components: {Avatar, AccountPanel, Languages, Notifications, FollowedDriversPanel}
})
export default class LoginAvatar extends mixins(UMBaseComponent, AuthComponent) {
@Setup(useQuasar)
$q!: QVueGlobals
...

No, this context can't be accessed when declaring a class field. It will be totally removed in the next version.
