Errors running the pre-built engines.

[Clancey]

I am getting the following output when trying to run on a Raspbery Pi 3 B. I followed all the instructions for using your existing pre-built engine. Any thoughts?

With which flutter version you compiled the app?

[Clancey]

Latest stable.

[GioPan04]

The prebuilt engines are compiled for flutter 1.17 if I remember correctly. Try to built yourself for your flutter version

[ardera]

Works fine for me with latest stable.

The only way this error can happen is when there is a version mismatch between flutter SDK and flutter engine. Minor version mismatches are okay, i.e. a 1.17.0 engine should work with a 1.17.5 SDK (it's not impossible that it won't work, in which case I'll just upload updated binaries.). The latest engine binaries I provide are for 1.17.0.

Are you sure the flutter engine you have installed on your target are the latest ones I provide on engine-binaries?

[Clancey]

So I had the right engine, but it looks like the build machine was on dev channel, Sorry about that!
