Droidcon London 2023: Google Home, But Better: Smart Home Display with Flutter

We may not have realized it yet, but Flutter could become the next big player on embedded devices.
We'll take a dive into running Flutter on embedded Devices and build our own Smart Home Display using Flutter, a Raspberry Pi and embedded Linux.
What's currently supported and what custom Embedder can we use to achieve this? How do we communicate between Flutter and the embedded hardware? How can we integrate and use Flutter in the Maker-Community to open up to the world of IoT?
This talk aims to show the potential of Flutter on embedded devices, to give a practical guide on how to start developing Flutter with a Raspberry Pi on embedded Linux, and to showcase a project where Flutter connects to the Internet of Things.
