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.
