1.0.0 - 2026-10-17

First release.

Added

• Native chat screen ZukkoChat for the Zukko Chat Widget API, plus a headless ZukkoChatClient.
• Three chat styles (smoothSilk, minimalClean, threadFeed), each in light and dark, with bundled fonts.
• Text, photos, files and hold-to-record voice messages; voice playback with seek and the real length shown before playing.
• Attachment sheet and voice-recording view designed for each style.
• Markdown in agent and AI messages (bold, italic, code, lists, headings, links, quotes, tables); the visitor's own messages stay plain.
• Link previews (enableLinkPreviews).
• Realtime updates with automatic reconnect and catch-up of missed messages.
• Opens with the newest 20 messages; older history loads 20 at a time on scroll to the top.
• Auto-scroll to new replies when the list is near the bottom or right after sending.
• Connection banner (no internet / connecting).
• Send limits with warnings (150 000 characters, 15 files, 40 MB per file).
• Six built-in languages (en, ru, uz Latin, uz Cyrillic, tr, kaa) following the app locale.
• User identity with ZukkoChatUser and identifierHash; one call to sign out (zukkoChatSignOut).
• Debug-only log with levels (ERROR, WARNING, info).

Security

• The session token (JWT) is stored only in an AES-encrypted local database; the key lives in Keychain/Keystore.
• Tokens and hashes are never logged.
• baseUrl must be https:// (plain http:// is rejected, also for localhost); the socket uses wss://.
• The HMAC secret never ships in the app; only the hash computed by your backend does. A rejected hash fails closed (INVALID_IDENTIFIER_HASH).

Requirements

• Dart ^3.13.0, Flutter >=3.47.0, iOS 15.0+, Android 7.0 (API 24)+.
