The Toyota Chief Engineer explains why they chose Flutter. They needed a way to build a user-friendly interface that would not only deliver smooth touch mechanics but also ensure safety. They also needed to be able to build a system that was able to handle all of the functions necessary to build a complex in-vehicle information system. They also wanted to build something that would stand out from the crowd. Flutter's best qualities include its ability to deliver a smooth UI, its ability to be a reliable UI toolkit, and its ability to deliver the best possible user experience.
