Toyota has adopted the flutter IVI shell in their newer cars. You could argue that it can also run on QNX but the real push behind it has been the growing interest and effort behind AGL.
QNX hypervisor architecture allows companies to adopt AGL gradually bringing in the productivity benefits of stuff like flutter and Linux. QT is hell, their entire moat has been the automotive industry/highly embedded devices and seeing Flutter chip away at even a small portion of it gives a lot of hope for a better competitive landscape for more productive and performant embedded guis.
