stream_chat_flutter_ai 0.1.0

Stream Chat AI Flutter components. Build AI-powered chat experiences with Stream.

0.1.0

First release of stream_chat_flutter_ai — Flutter UI components for building LLM-driven chat experiences. The package has no dependency on stream_chat, stream_chat_flutter or any other Stream Chat package: every widget takes plain strings, callbacks and controllers, so it drops into any Flutter app and pairs with any backend or LLM provider.

✅ Added

• StreamingMessageView — renders markdown with a character-by-character typewriter animation, for showing an AI response as it streams in. TypewriterController and TypewriterBuilder drive the same effect on a layout of your own.
• AIMarkdownBody — the markdown renderer without the animation. LaTeX and syntax highlighting are opt-in through the mathBuilder and codeHighlighter hooks, so neither pulls a dependency into hosts that don't want one.
• CodeBlockView — a fenced code block with a language label and a copy-to-clipboard button.
• ChartView and USpec — line, bar, area, scatter, bubble, pie, histogram and heatmap charts. USpecParser reads USpec, Chart.js, Plotly, ECharts, Highcharts and Vega-Lite payloads, ChartThemeData themes them from your app's ThemeData, and every chart describes itself to a screen reader.
• AITypingIndicatorView — animated LLM states such as "Thinking…" or "Checking sources…".
• ChatComposer — an AI composer with attachments, chat options, and a send button that becomes a stop button while a response streams. Its leading, trailing, input and attachment-sheet slots are replaceable through ChatComposerFactory.
• AISuggestionsView — a row of quick-reply chips for a new-chat landing screen.
• SpeechToTextButton — dictation into the composer, either standalone or folded into the composer's own send control with enableSpeechToText: true.
• AIToolRegistry — client-side tool calling. Declare AIClientTools, hand their registrations to your backend, and dispatch the agent's invocations back into your app.
• AITranslations — every string the package renders is translatable, through an AITranslationsDelegate for the app's locale or an AITranslationsScope for a subtree.
• AITheme — a ThemeExtension carrying ChartThemeData, ComposerThemeData and SuggestionsThemeData, narrowed to a subtree with ChartTheme, ComposerTheme or SuggestionsTheme. Every field is optional and falls back to your app's ThemeData.
