the modern chat input composer layout to better handle vertical
space and alignment. Change the row crossAxisAlignment from
center to end so controls align to the input bottom. Wrap the animated
container with a ConstrainedBox that limits the composer max height to
25% of the screen, preventing excessive growth on tall displays.
Reorder and clean up the AnimatedContainer/decoration block, extracting
the composer radius constant and preserving styling (background color,
border color/width). Move the text field and inline mic into the same
row structure under the constrained container and retain the isActive
flag and padding. These changes prevent layout overflow, ensure a
consistent border radius, and improve visual alignment of controls.
Remove internal reasoning from copied message text to avoidleaking implementation details or developer-only when a
user content from the chat- In chat_pagecopyMessage, cleaning steps to:
- <details type="ing">...</details blocks
- <think>think> and <ing>...</reason> tags
- trim leftover whitespace before writing to the clipboard
- In assistant_message_widget._buildSegmentedContent, remove an
unused hasMediaAbove calculation and a conditional spacer that added
extra top padding before reasoning tiles. This simplifies rendering
logic and avoids relying on removed spacing behavior.
Hide archived assistant variants in the linear chat view and track
previous assistant as versions so regenerated responses do not
duplicate or lose history. When regenerating, mark the previous assistant
message with an archivedVariant flag for the UI and keep it in server
history. Add a ChatMessageVersion model and a versions field to
ChatMessage to store prior generated variants. Implement
archiveLastAssistantAsVersion in chat providers to snapshot the last
assistant message into versions and reset the message for a fresh
streamed generation. Finalize flow updates to attach an adjacent archived
assistant as a version when needed so the UI can present a switcher
between current and past variants. These changes prevent duplicate
messages, preserve previous responses, and enable variant switching.
Add Riverpod-aware image header and cache manager support for network
images used in avatar and markdown widgets. Convert AvatarImage to a
ConsumerWidget and read a self-signed cache manager and HTTP headers
from Riverpod so CachedNetworkImage can send auth/custom headers and use
the provided cache manager. In Markdown image builder, obtain headers
and cache manager from a ProviderContainer (via ProviderScope.containerOf)
to enable the same authenticated loading in non-consumer contexts.
Introduce image_header_utils.dart to centralize building Authorization
and custom headers from auth/api providers, with helpers for Ref,
WidgetRef, and ProviderContainer. Add dependency adjustments in
pubspec.lock for flutter_cache_manager and http marked as direct main.
These changes ensure protected images (self-signed or auth-required)
load correctly across the app and reuse the configured cache manager.
Add rendering and support for a karaoke-style text-to-speechprogress bar in assistant messages so users can see the currently
spoken sentence and highlighted word during playback.
- Append TTS karaoke bar to AssistantMessageWidget when the message is
the active TTS target and playback is speaking/paused/loading.
- Implement _buildKaraokeBar to render the active sentence with a
highlighted word span, using ConduitCard and theme styles.
- Import conduit_components for shared UI primitives.
- Extend TextToSpeechState with sentence data:
sentences, sentenceOffsets, activeSentenceIndex, and per-word
progress (wordStartInSentence, wordEndInSentence).
- Add provider callbacks wiring: onSentenceIndex and
onDeviceWordProgress handlers (hooked into TTS backend).
- Prepare sentence splitting and word-progress plumbing in the TTS
provider (prepares data used to drive the karaoke display).
This change improves UX by visually indicating the spoken sentence
and current word during TTS playback, aiding comprehension and
accessibility.
- Updated multiple instances of the 'monospace' font family to use AppTypography.monospaceFontFamily for consistency across the application.
- This change enhances maintainability and ensures a unified typography approach throughout the app.
- Introduced new regex patterns to remove thinking and reasoning blocks from markdown input.
- Added functionality to strip emojis from the text, improving clarity for TTS.
- Implemented HTML entity decoding to ensure proper text representation.
- Replaced the existing sanitization method with a more comprehensive markdown-to-text conversion approach, enhancing performance and maintainability.
- Implemented state-based overlay color changes for the chat input's InkWell widget to improve user feedback during interactions.
- Adjusted the color of the chat input icon to align with the primary button text color, enhancing visual consistency and usability.
- Changed the placeholder color in the modern chat input to use the input text color with adjusted alpha for better contrast and visibility in both light and dark themes.
- This enhancement aims to improve user experience by ensuring the placeholder text is more legible across different brightness settings.
