From the docs:

> **Note:** `idx-template.nix` always uses the `stable-23.11` [Nix channel](https://search.nixos.org/packages).

This prevents me from using the latest Dart version during the bootstrap script of a template. The latest available version of the dart nix package on this channel is 3.1.3, which is from Sept. 2023. I would guess its the same for other packages.

Can you update the nix channel for templates to the latest (currently 24.11)?

_I tried downloading and unpacking the dart binary manually, but that fails due to some dynamic loader error. The fixes described [here](https://nixos.wiki/wiki/Packaging/Binaries) don’t work. I don’t have any info on what environment the bootstrap script is run on. Because of that and because it takes a lot of time to recreate projects, its really painful to debug._

Looks like the docs are outdated. 24.11 should be supported. Can you try changing channels in dev.nix to stable-24.11 please? Let us know if it doesn’t work

This is about the `idx-template.nix` file, not the `dev.nix`
