Change looks fine 👍

I'm curious to know why do you need to change this though.
We need to make some assumptions from time to time (e.g. where the codegen output folder is and so on) so allowing for full customization is not always possible.

The main reason for me to change the build directory is to avoid having to rebuild everything when node_modules gets changed. Building from source can be quite long so keeping the build cache is nice by moving the build directory to somewhere else.

This used to work with ndk build so I think changing build dir should be supported and is possible to avoid assuming the location.

Following up here: how do you handle iOS build dir?

The reason why I'm asking is that we have build/ hardcoded in several other places in the codebase:

For iOS the build is already outside node_modules in ~/Library/Developer/Xcode/DerivedData afaik so I don’t do anything special. Codegen output is in /ios/build, but that doesn’t really cause problems.

I think it is fine to assume build path in certain cases when we control output, but in the case of android build directory it is possible to change via gradle so we should use that config value.
