You can see the steps:

nix flake new -t github:rencire/devix/main#flutter

cd flutest

direnv allow  

and the error is there.

[rencire]

hmm, not sure why error is happening. However, after i run nix develop, dependencies install as normal. What happens when you run nix develop after direnv allow?

You can't do nix develop without the flake working...

[rencire]

Right, sorry not sure why it was still working for me on local machine, even with the error. I pushed a file rename fix, so hopefully that fixed it.

Don't worry it's working really fine now. I can build the apk right now. You're a master <3

EDIT:

i've got this issue:

it's related?

EDIT 2:

Another issue I see is in the flake:

ln: failed to create symbolic link '/home/linuxmobile/.config/flutter/settings': No such file or directory

[rencire]

For first issue, have not seen this before. I haven't tested this on a linux os yet (working on macos). Will need to do some debugging for this on my linux machine when I have time.

For second issue, are you missing the /home/linuxmobile/.config/flutter/ folder path? My understanding is that this should exist from using flutter, but not sure when it gets added by flutter.

I added a line to create the folder if it doesn't exist, so can try again (See: 10beadd)

For context, the reason I had to symlink the flutter settings file so that the flutter sdk uses the android sdk from nixpkgs, not from my Android Studio installation.

Well, we need to fix the stub-ld error only 👍🏼.
