[0.0.3] - 2025-04-14

Added

• Markdown Support: Bot responses are now rendered as Markdown using flutter_markdown, allowing for richer text formatting (bold, italics, lists, links, etc.).
• Citation Handling: Added support for receiving citation data from the backend.
• Citation Toggle: Added showCitations parameter to ChatWidget to allow developers to show/hide citation information in the UI.
• Enable/Disable Toggle: Added isEnabled parameter to ChatWidget to allow developers to enable or disable the chat functionality dynamically.
• Thread ID Context: Implemented handling for thread_id received from the backend (metadata type response) and sending it back on subsequent requests to maintain conversation context.
• New Callbacks: Added optional onCitationsReceived and onThreadIdReceived callbacks to ChatWidget.
• Error Message Type: Introduced an explicit error message type for better error handling and display.

Changed

• Backend Response Handling: Refactored ChatService and MethodChannelChatPlugin to process structured JSON responses from the backend with distinct type fields (content, metadata, citations, error) instead of just plain text streams.
• Stream Finalization: Improved stream handling in ChatService to correctly identify the end of a response (including handling custom stream_end events) and update the message state (isWaiting=false) reliably.
• API Signatures: Updated streamResponse method signature across ChatPlugin, ChatPluginPlatform, and MethodChannelChatPlugin to accept threadId and return Stream<Map<String, dynamic>>.
• ChatMessage Model: Updated ChatMessage to include type, threadId, and citations fields.

Fixed

• Persistent Loading Indicator: Fixed an issue where the loading indicator on bot messages would not disappear after the response was fully received.
• Type Errors: Corrected type mismatches in ChatBubble related to BorderRadiusGeometry/BorderRadius and EdgeInsetsGeometry/EdgeInsets.
