Sona | AI Persona Chat and Companion App – Flutter UI Kit

Sona is a production-quality Flutter front-end UI kit for building an AI-persona social & companion app — discover AI personas, chat with them (text, voice & video-call UI), follow a social feed, create your own persona, and monetize as a creator. Built with Flutter, Material 3 and Riverpod, it ships 60+ screens across 63 routes and passes flutter analyze with zero issues out of the box.

Every persona is drawn by an original, code-generated illustrated-avatar engine — no stock photos, no emoji-on-a-box placeholders. Nothing bundled needs a third-party license.

What’s inside (60+ screens)

• Discover & Explore: a personalized home feed, trending personas carousel, category browse, search with results, persona “stories” with a full-screen viewer, and a social post feed with a post-detail screen and comment composer.
• Personas: rich persona profiles with stats, personality, traits and starters, plus per-persona Memory (“what {name} remembers”, editable), Diary, relationship Timeline, personality Evolution, and 2-persona Duets and live Events / Rooms.
• Chat: a full 1:1 chat with personality-flavored replies, message starters, timestamps, activities, attachments and a voice-note recorder UI, plus dedicated voice-call and video-call screens and multi-persona rooms.
• Create & Creator Studio: an 8-step create-a-persona wizard (identity, avatar, personality, voice, knowledge, privacy, monetization, preview), a creator studio with analytics, a knowledge base, pay-per-view media, A/B versions and a verification flow, plus a persona-template marketplace.
• Monetization: a credits wallet, buy-credits packs, Pro upgrade paywall, per-persona subscribe, tipping, creator earnings, payouts, a transactions ledger and transaction detail — all wired to a live in-app credits balance.
• Engagement & rewards: daily rewards, achievements, leaderboards, referrals/invite, scheduled check-ins, an interests picker, a daily mood check-in and a shared “your world” facts space.
• Profile, settings & safety: profile, edit profile, saved, “my personas”, a notifications center, and grouped settings (appearance/theme, notifications, privacy & safety, language, help, about, blocked, subscriptions, legal). Safety is built in: an age / consent gate, a persistent “AI, not a real person” disclosure, and block & report flows.
• Auth: login, sign-up, password-reset and an in-app support chat.
