ianvs_agent_chat 0.3.0

Reusable Flutter agent chat UI with streaming messages, tools, permissions, ACP integration contracts and an OpenAI-compatible LLM adapter.

0.3.0

• Extract pure Dart models and sessions into ianvs_agent_core; move native diagrams into optional ianvs_mermaid.

• Share message frames, literal code previews and presentation-only decision cards with mixed timelines. Tool cards support hidden default details, host footers and controlled expansion.

• Add PromptInput.hosted for host-owned editor/action subtrees without creating input controllers or sending/stopping actions. Keep editor composition, selection and focus through slot changes.

• Use the same frames and decision surfaces in the built-in conversation and permission UI, with consistent role padding and compact layouts.

• Preserve ianvs_markdown's theme and typography for messages and summaries, and use its built-in code blocks and links. Keep host link handling, Mermaid rendering, blocked-image copying and render budgets.

0.2.0

• Add host-owned ChatComposerController and immutable draft submissions with explicit accepted, queued and rejected receipts. Preserve drafts on rejection or stale receipts and prevent concurrent submission.

• Keep legacy ChatSession.send completion timing; LLM and the example opt into admission. Add CallbackSubmissionChatSession and execution-policy/queue callbacks.

• Use local composer constraints, shared content width and compact margins. Keep all typed configuration options and advanced menus reachable.

• Pause streaming scroll follow while reading older messages and expose Jump to latest.

• Default to portable Flutter semantics. ChatNativeTextFieldScope enables the ACP native proxy only in hosts that register it.

• Render chat through ianvs_markdown ^0.3.1 with the standard GFM preset and shared budget scanner. Retain chat code/diagram builders, safe images, block selection and host link handling.

• Adopt ianvs_design for shared controls, typography and light/dark themes.

• Resolve partial ChatThemeData color overrides against the ambient theme and expose the conversation reading font size.

• Switch code highlighting, Mermaid diagrams and permission feedback with the host appearance.

• Remove the application-specific ui/theme/app_theme.dart and ui/theme/app_design_tokens.dart; use the public Ianvs Design APIs instead.

0.1.0

• Extract the conversation timeline and composer from the Ianvs ACP desktop app.
• Add backend-neutral session state, actions, capability flags and typed message helpers.
• Include streaming Markdown, code, images, Mermaid, tool activity, plans, permissions and queued prompt presentation.
• Add per-conversation themes, primary composer labels, tool presentation rules and replaceable platform services.
• Include an optional OpenAI-compatible LLM adapter with bounded SSE parsing, independent conversation history, cancellation, tool execution and approval callbacks.
• Include a standalone macOS example and an in-memory demonstration backend.
