flutter_ai_elements 0.1.0

Composable, themeable Flutter UI for AI chat — conversation, message bubbles, a streaming-aware composer, and a loader — styled entirely through a mobile-first AiThemeExtension. No shadcn/forui dependency.

Changelog

0.1.0

Initial release.

• AiThemeExtension — a ThemeExtension of design tokens (bubble colors, shapes, ambient shadow, spacing, typography, motion, haptics) with copyWith, lerp, of(context), and a mobile-first fallback().
• Presentational widgets: AiMessageBubble (renders every AiPart type; streaming-safe semantics), AiConversationView, AiComposer (Send↔Stop swap, haptics), AiLoader.
• Controller-bound widgets: AiChat (live transcript with auto-scroll and a thinking loader) and AiPromptInput.
• AiResponse — a dependency-free Markdown renderer (headings, bold/italic, inline + fenced code, lists, blockquotes, links); MarkdownTextRenderer wraps it and is now the default AiTextRenderer. PlainTextRenderer remains.
• AiChainOfThought (stepwise timeline), AiTask (agent checklist), AiInlineCitation (numbered badge), AiBranch (version navigation), AiImage (loading/error/tap-to-zoom).
• Input upgrades: AiComposer gains an attach button, a model-selector slot, a voice button, and removable attachment previews; AiPromptInput stages attachments and switches models via the controller. AiModelSelector, AiConfirmation (approve/deny), AiContextMeter (token usage), and AiShimmer (loading skeleton).
• AiLiveSession — a full-screen, engine-agnostic Live voice surface (animated orb reacting to amplitude + status, live transcript, mute/keyboard/end). UI only; drive it from a realtime audio engine.
• Performance & a11y hardening: AiResponse parses Markdown and builds gesture recognizers once per text change (not every frame) — important on the streaming hot path; AiLiveSession animates only the orb (60fps no longer rebuilds the conversation); message bubbles no longer subscribe to window size in the common bounded case; list items carry stable keys; the composer measures with the ambient text scale + direction; disclosure widgets expose button/expanded semantics; modal sheets scroll; high-traffic layout uses directional insets/alignment for RTL.
• Re-exports flutter_ai_client (and flutter_ai_core).
