add nix shell for development

[theotheroracle]

don't need to merge, just thought i'd offer since i set it up

[Airyzz]

Thanks for this! while I'm interested in nix i'm not really sure if I want to merge right now as I dont have any necessary experience to provide support in this area. If someone is able to provide support in maintaining this side of things that would be cool, because I think it would be sweet to eventually have official support for this

[theotheroracle]

i will personally be maintaining it, so if there's ever any issues with it, i'll take care of it

[Theaninova]

I got a more comprehensive one that sets up Android CLI compilation as well

.envrc

use flake

This was the best I could come up with, no idea if you can convince Gradle to not download Java without this line commet/android/gradle.properties

+ org.gradle.java.installations.fromEnv=JAVA_8_HOME,JAVA_17_HOME

[theotheroracle]

one thing to note, is that i couldn't only get the cmdline tools, which flutter doctor complains about, without using openjdk8, i have no idea why modern versions weren't working

[Theaninova]

There's a dependency that requires JDK8, you need both for it to compile. I have it solved in my flake.

if you open a pr for your flake I'll close mine
