isPublic static method
Checks whether key is designated as client-public.
The check is an exact prefix match: key must begin with publicPrefix ('BLOOM_PUBLIC_').
Variables that merely contain this substring elsewhere in their name are not public.
BloomEnv.isPublic('BLOOM_PUBLIC_API_URL'); // true
BloomEnv.isPublic('DATABASE_PASSWORD'); // false
BloomEnv.isPublic('NOT_BLOOM_PUBLIC_KEY'); // false
Implementation
static bool isPublic(String key) => key.startsWith(publicPrefix);
