Flutter is an UI Framework based on Dart, made by Google. While the primary focus of Flutter is mobile platforms like iOS and Android with a growing support for the Web, Flutter is also heading towards Linux and Windows. Flutter is also used at Google to provide the HMI for some of Google's own devices and will become even more important once Fuchsia will be succeeding Android.
So I wondered if I would be able to run Flutter on an UX-Gruppe MACH platform (which is an iMX.6 SOC). The short answer is, yes you can.

In this blog I will explain how you can setup everything for a generic ARMv7 Embedded Linux target. Since I do not know which hardware you may have at hand, I need to assume that you will be able to fill the gaps. An i.MX6 with a recent Buildroot or Yocto BSP is a good starting point.

I will show you the basic dependencies and commandlines you need in order to cross-compile Flutter for ARMv7. What you can also expect is a general instruction of what needs to be done in order to finally run a Flutter App on your platform (after you compiled the engine).
