kTranslationVersionSeparator top-level constant

String const kTranslationVersionSeparator

Separates a translation key from the source-text version hash in a versioned storage key, e.g. welcome_key@@a1b2c3d4e5f60718.

Chosen to be extremely unlikely to appear inside a real translation key, so versionedTranslationKey round-trips cleanly and legacy plain keys can be told apart from versioned ones during migration.

Implementation

const String kTranslationVersionSeparator = '@@';
