Trying to get flutter pi working, but fails with "Artifacts for engine x are not yet available."

I followed the instructions in the README file, but I can't seem to get it working.

Everything seemed fine until I tried running the build command, which failed with the following output:

tobias@tobias-G5-KC:~/Downloads/sample$ flutterpi_tool build --arch=arm64 --cpu=pi3 --release

I'm running this on Ubuntu 24.04. I'm very new to Flutter and related tools, so I'm not sure what this error means or how to resolve it. Any help would be appreciated!

I fxied the issue. Here's what helped me (Answered by anlumo on the flutter discord):

it means that there are no engine binaries with that hash here: https://github.com/ardera/flutter-engine-binaries-for-arm/tags
so, you're running some version of Flutter that's not supported by the download tool. You have to either build it yourself or use a different version of Flutter.
I just checked, the hash is from the latest version 3.24.5, but the engine is only available up to 3.24.4. Usually they're released pretty quickly after a Flutter upgrade, but maybe @ardera is busy right now.
Revert to 3.24.4 to fix this.
