iUnreallx/ReDrive ? reverse-engineered prompt

Build me a Flutter mobile app for OBD2 car diagnostics called ReDrive.

I want a clean, modern dashboard app that connects to an ELM327 adapter over Bluetooth, Wi Fi, or USB, then shows live car data like RPM, speed, coolant temperature, voltage, and other telemetry in a simple easy to read interface. It should also be able to scan for trouble codes, show basic explanations, and let me clear errors when possible.

Please make the app feel fast and uncluttered, with a nice home screen, a connection screen, and a bottom navigation style layout. Include a demo mode so the app still works without a real car connected, and add automatic reconnect behavior if the adapter drops out. Keep the design focused on driving, so the important numbers are easy to see at a glance.

If you need to check anything about Flutter or OBD2 handling, look up current docs online and build it in a sensible way.
