How to fetch environment variables?

[noga-dev]

const testEnvVar = String.fromEnvironment(
    'SUPABASE_URL',
    defaultValue: 'defaultVal',
  );

The env var SUPABASE_URL comes built in as a default secret, per https://supabase.com/docs/guides/functions/secrets, yet defaultVal is returned.

Secrets can be read using

Deno.env.get('VARIABLE_NAME')

Secrets must be managed by Supabase CLI with standard supabase secrets list/set commands. Secrets are written in environment files (DO NOT ADD THEM TO GIT, exclude them in .gitignore):

./supabase/.env (for PRODUCTION)
./supabase/.env.local (for local dev)

In order to make work local secrets during development, you need to add an extra --env-file file parameter to your serve command:

supabase functions serve dart_edge --no-verify-jwt --env-file ./supabase/.env.local

Hope this helps

PS: Maybe we should add this to the README.md, isn't it?

Oh, I didn't realize I had access to Deno as an object inside main.dart. Thanks for this!

Works great and should definitely be added to the readme.

Leaving this issue open for the maintainers to address the docs/readme.
