Start your adventure armed with this knowledge:
Dashboard 2 uses Vue 3 Options API and Vuetify component framework
You don't need all that ugly "xxx"+scope.$id stuff and there is no jQuery. Instead of applying ids to your components you use ref instead. Vue 'ref' Attribute
On top of what I wrote here: Subflow - UI Group - #11 by Steve-Mcl , most things have an immediate alternative. e.g. md-button becomes v-btn and the docs for v-btn are here: Button component — Vuetify
Lastly, the docs for dashboard 2 are pretty decent: Template ui-template | Node-RED Dashboard 2.0
