flutter build bundle doesn't work in raspberry pi 4 about flutter-pi HOT 1 CLOSED

I think the flutter SDK isn't yet ready to be used on ARM / AARCH64, so it probably won't work on the Pi 4. Maybe you can get it to work with a lot of hacks, but I don't know how.

To be more precise, this is the exact error:

[...] the snapshot requires
'[...] x64-sysv' but the VM has '[...] arm-eabi hardfp'

The flutter SDK uses dart internally for a lot of it's tools. So when you run flutter build bundle, the flutter script will launch some dart snapshot internally that completes the task of building the asset bundle. Dart snapshots are basically dart code compiled to machine code, so a dart snapshot generated for x86-64 cannot be run on ARM 32bit hardfp, but that's exactly what the flutter script tries to do in your case.

Maybe it's somehow possible to regenerate the snapshots for arm-eabi hardfp, or to avoid using snapshots at all (dart can interpret and JIT-compile too) but I don't know how to do that. You should consider opening an issue at the official flutter repo or maybe someone on the flutter discord can help you. Even then, if you fix this issue, you may run into other incompatibilities.

Also, I really recommend building the asset bundle on a machine more powerful than the Pi 4. The build takes ~10 seconds on my desktop, I'm sure it'll take a lot longer on the Pi 4.
