I am pushing my Flutter Web project to Vercel.
Currently using Supabase as backend.

I need to access the SUPABASE_SERVICE_ROLE_KEY environment variable for my web app to work.

I am aware of the Vercel Environment Variables but don’t know how to access them client-side.

For node.js you can do something like process.env.VARIABLE but I cannot find dart client documentation for the same thing.

I cannot do --dart-define because my build command will be too long.

What are my options?
