We use Flutter because it is one of the best options for building MVPs with quality, even faster than JS Web-based hybrid mobile applications. I personally love hot-reload provided by Flutter with QEMU and the Widget tree architecture that creates an awesome readable code.
We use Kubernetes because it scales big and solid. We are a startup with limited resources so, the straight-forward decision is to get the DevOps stuff as lightweight as possible with each release, letting the process as painless as possible in time = money.
