dart - Does @observable have to be used on every field? -

i've noticed if not use @observable in of web ui code fields/members changes picked automatically data binding syntax.

the issue run when picking 1 field in class extends webcomponent , applying @observable annotation, other fields dont bind correctly , display changes.

is known issue or correctly functionality?

if use @observable annotation once, should applying fields?

as mentioned in post, have option of marking class @observable.

you're caught between observables , watchers. watchers (and dispatch) old way, phased out. observables new way. in order not break old clients, kept watchers in. if used @ least 1 @observable, watcher system disabled.

the new mdv v2 implementation getting ready. suggest use @observable want observed. stop using dispatch() everywhere. also, stop using observable top-level fields, because won't bindable node.

apologies, things in state of flux. suspect things settle quite soon.

i suggest reading more mdv v2 here: https://github.com/toolkitchen/mdv/blob/stable/readme.md ready change.

i suspect @observable continue option, it's ok keep using now.
