My project uses a single large text file with a collection of English words. This file should never be changed by code, only read from.

Is there a standard location in the file structure for a file like this?

Flutter uses the /assets folder, but my project is in pure Dart.
I have also seen people use a /data folder but I can’t find any official documentation for this.

I checked out the Dart package layout conventions but there is no mention of static data files, unless I missed something.
