Automotive Grade Linux All Member Meeting Japan 2026

A modern vehicle works on a multi-display platform seup. Center stack, instrument cluster, heads-up display, rear-seat entertainment, and the driver's companion mobile app all compete for coherent UX — and Flutter's single-codebase promise makes it uniquely suited to unify them.
But "write once, run everywhere" demands more than responsive layouts. This session presents an architectural pattern for building multi-display Flutter applications on AGL, drawing from VGV's experience delivering large-scale, modular Flutter systems.
We'll introduce a layered approach separating platform integration from shared business logic and a design-token-driven UI layer that adapts to display size, pixel density, safe areas, and interaction mode — touch, rotary controller, or voice. We'll cover state synchronization across displays, graceful degradation when a secondary display is unavailable, and how to structure your Dart package graph so cluster-critical code compiles independently of infotainment features.
