Upload Flutter Instrument Cluster app

Instrument Cluster demo app which shows speedometer
tachometer guages, temperature and fuel bars and some
indicators like turn indicators, engine malfunction,
lights, cruise control, lane assist. KUKSA.VAL is the
data source for the widgets.

This app depends on several plugins and all the plugins
have an OSI-approved license.
