Building flutter tool on ARM macOS host fails

Building flutter tool on ARM macOS host fails with:

Building flutter tool...
oah error: unhandled 16KB-unaligned mmap addr=0x0 len=0xdd28c0 offset=0x1000 prot=1 flags=2

oah is Rosetta. I see old blogs and ebooks mentioning gdb --oah when debugging Power-PC on Intel.

I'd guess this happens when we try to load app-jit snapshot for the kernel service. ARM64 Mac OS has 16KB pages, and apparently our app-jit snapshot loading code expects 4KB pages. mmap is supposed to return EINVAL though if offset is not a multiple of page size.

When does this fix will be applied to flutter ? I am running into the same issue

[jmagman]

935b69e rolled in flutter/engine#19577 which rolled in flutter/flutter#61090 which is in Flutter 1.20.0-7.0.pre. So that's in the stable channel.
@MichelMelhem what's the output of flutter doctor -v where you are seeing this?

[MichelMelhem]

@jmagman When running flutter doctor -v I'm getting this output :

 flutter doctor -v

I'm running an apple dev kit that is using apple silicon.

Do you know what version of Flutter are you on? I believe it should be fixed on the stable channel. I was just on a DTK where it was working on master, though I didn't try stable.

[jmagman]

In any case you will need to be on master to flutter run on a real device to pick up flutter/flutter#68855

@jmagman Update : I'm now able to successfully run flutter doctor but my app still won't compile running the same issue that was mentioned before:

@MichelMelhem Apple Silicon isn't fully supported for Flutter yet, even on the master channel. And definitely not on the stable channel. We're tracking with flutter/flutter#60118. If you encounter issues that aren't on that list, please file a new issue in the flutter/flutter repo and we can take a look.
