Dart Encryption
Dart is the language behind Flutter: one codebase for mobile, web, and desktop UI. Compilation to JavaScript and native snapshots means your strings land in bundles users can unpack. The tooling is slick; the attack surface is still “everything ships to the client.”
Firebase keys, analytics IDs, and deep-link secrets often get checked into the repo as plain constants. StringEncrypt gives you Dart that rehydrates those values at runtime so a strings pass over the release artefact is less boring.
String encryption supports both UNICODE and ANSI strings.
