animated_streaming_markdown 0.3.7

Flutter markdown streaming package for Android/iOS/macOS/Linux/Windows/web, with Tree-sitter WASM and KaTeX math support.

0.3.7

• Represent direct inline links as MarkdownInlineLink semantic snapshots, including the current label, destination, completion state, source, and offsets when a stream ends before ).
• Stop exposing unfinished link Markdown as literal text. The default renderer hides a label-only tail, shows the arriving destination, and switches to the linked label on completion. An arriving destination is styled and tappable before ) arrives; incompleteLinkTextBuilder allows downstream applications to choose label-only or hidden projections without reparsing.
• Keep custom image and LaTeX widgets selectable, and add AnimatedMarkdownSelectable for fully custom block objects while copy remains backed by the original Markdown source. Its default behavior is atomic; .text adapts Text, RichText, and Flutter SelectableText to character-level selection, while .fragments and AnimatedMarkdownSelectionFragment map composite widget regions.
• Keep the first pointer edge collapsed instead of briefly selecting to the end of its visual line, and preserve a finalized range when a mobile long-press targets a word already inside that selection. A single desktop click now dismisses the finalized range without extending a stale anchor, while double- and triple-click retain native word and paragraph selection.
• Preserve finalized browser selection across scrolling, tab changes, and window changes while still dismissing it for a deliberate primary click elsewhere inside the application.
• Add AnimatedMarkdownSelectionValue and the optional AnimatedMarkdownSelectionController for directional, source-backed selection, including clear() and selectAll().
• Add AnimatedStreamingMarkdownSelectionArea for selectable sliver content; box renderers continue to host their own selection area automatically.
• Match TextField edge-drag behavior with frame-driven vertical and horizontal auto-scroll, source-stable anchors, endpoint re-hit-testing, and immediate cancellation without fling or post-release momentum.
• Reveal keyboard and programmatic selection endpoints with configurable selectionScrollPadding, using the same 100 ms caret-reveal timing as editable text.
• Preserve directional selections through streaming append, block replacement, transient sliver unmounts, and geometry leases while an actively selected block changes.
• Keep highlight paint independent from Flutter's transient selection geometry clears and batch selectable rehydration, preventing blank or doubled frames during mouse, touch, and handle drags on old and current Flutter SDKs.
• Paint selection as one continuous line layer instead of per-token shadows, derive animated-word highlights from their actual rendered glyph boxes so wrapped lines do not expose token seams or select trailing empty width, cover the full decorated inline-code box when its token is completely selected, hit-test inline code against its real padded render geometry, flatten its selected background into the surrounding line instead of a rounded pill, cover the real bounds of inline/block images and LaTeX widgets, and preserve touch long-press, handle, and keyboard selection across text and non-text content.
• Complete semantic projection and selection geometry for formatted headings, callouts, front matter, footnotes, nested HTML blocks, lists, tables, code, images, and formulas in both box and lazy sliver renderers.
• Unify plain, raw Markdown, rich HTML, keyboard, context-menu, browser, and mobile-toolbar copy paths around the controller source range. Rich clipboard writers are included for Web, Android, iOS, macOS, Windows, and Linux, with plain-text fallback when a host rejects HTML.
• Keep streamed assistant renderers and their parser/token state alive through example chat-list recycling, so adding a message does not replay completed responses or reset their selection.
• Add TextField-reference, controller, box/sliver, browser, and offline native integration regression coverage for selection and auto-scroll lifecycle.
• Refresh the public demo recording at 1440x900 and the README GIF at 960x600 with deterministic selection, incomplete-link, and custom-widget fixtures.
• Preserve the Flutter 3.10 minimum while supporting current stable releases by embedding the view-only KaTeX renderer and replacing its version-sensitive layout callback with a stable LayoutBuilder baseline adapter.
• Make the example project's Dart and dependency constraints resolvable from Dart 3.0 through current stable, and gate both Flutter 3.10.7 and stable in CI.

0.3.6

• Replace overlay-derived selection tracking with render-backed absolute range selection, keeping anchors stable through streaming and viewport scrolling.
• Support partial text selection inside tables, selection continuation across table boundaries, and vertical/horizontal edge auto-scroll while dragging.
• Compact settled animated tokens into lighter static spans without shifting rendered layout, preserving the established word-by-word animation behavior.
• Add the Gravity example animation while restoring Fade as the default example preset.
• Refresh the README/demo video, package API documentation, website documentation, and forward roadmap for performance and requested features.
• Remove stale preview and internal validation artifacts from published package contents.
• Repository maintenance: normalized historical Git author and committer metadata to samnn152 <[e-mail]>. Earlier commits may have appeared under other local Git identities for the same maintainer, including Ngô Ngọc Sâm, Sam Ngo Ngoc, and machine-local hider152 emails.

0.3.5

• Hotfix pub.dev platform metadata to declare Flutter web support explicitly.
• Keep the published web support messaging aligned with the shipped zero-config WASM-backed web implementation.

0.3.4

• Add CI/release gates for committed WASM parser assets.
• Allow web parse workers to use Tree-sitter WASM when the generated asset is available, with pure-Dart fallback otherwise.
• Promote Flutter web support as zero-config for package consumers by bundling generated WASM parser assets as package assets.
• Replace the example app with a real streaming Markdown chatbot for Ollama, ChatGPT/OpenAI, Claude, Gemini, and Grok/xAI providers.
• Add a static Flutter web chatbot demo for the documentation site.
• Add inline image rendering customization, intrinsic-size handling, and baseline alignment controls.
• Add KaTeX-compatible LaTeX math rendering for inline $...$ / \(...\) and display $$...$$ / \[...\] expressions using flutter_math_fork.
• Improve chat example render sequencing so streamed Markdown waits for parser, block reveal, and token animation settlement before allowing the next send.
• Rework Markdown table rendering to support left-aligned viewport framing, row-by-row reveal, more readable colors, and stable shared column widths on web and native targets.
• Raise the Dart SDK lower bound to >=3.0.0 to match the math renderer dependency and current Flutter web support.
