Fixed #

• The widget readOnly flag no longer lets keyboard shortcuts edit the document. QuillKitEditor(readOnly: true) over a controller whose own readOnly was false still applied Ctrl/Cmd+B, the header and indent shortcuts, and undo/redo — silently mutating a document the app had declared read-only. The shortcut actions now consult the same combined predicate as the caret, IME and text actions.
• Async continuations no longer touch a disposed controller. Paste and the link/colour dialogs resume after an await; if the editor was disposed in the meantime the document's closed change stream threw a StateError in release builds. Added QuillKitController.isDisposed.
• controller.changes survives a document swap. It returned the current document's stream and document = closed the old one, so an autosave subscription silently stopped firing after loading another document.
• A controller swap no longer leaves the context menu and selection handles bound to the previous controller.
• QuillKitViewer now applies theme.horizontalPadding, matching the editor as its documentation claimed.
• DropdownAttributeItem no longer throws on an empty options list.
• The editor no longer issues a TextInput.show platform call on every controller notification, which also re-summoned a keyboard the user had dismissed.

Accessibility #

• Checklist checkboxes are now real checkboxes to assistive tech. They were a 16px GestureDetector with no semantics at all: a screen-reader user could not tell a checklist item from a bullet, could not know whether it was checked, and could not toggle it.
• The editor now exposes text-field semantics (textField, multiline, readOnly, focused, label, and the placeholder as a hint). Previously screen readers announced the content as a stack of static text and never said it was editable.
• Colour swatches are labelled, selectable buttons instead of ~50 identical unlabelled targets.
• Decorative bullet glyphs and code-block gutter numbers are excluded from the semantics tree; ordered-list rows merge their ordinal with the item text. Checklist rows stay separately actionable.
• The caret holds solid instead of blinking forever when the platform requests reduced motion, and stops its timer.
• The header dropdown is named for the control ("Paragraph style") rather than for whichever option happens to be selected.
• The colour picker's hex field reports a real, localizable error instead of announcing the literal string #rrggbb.
• New localizable strings: editor, checklistItem, paragraphStyle, invalidHex.

Changed — layout #

• Interactive controls now meet the 48x48 minimum tap target. Flutter clips hit testing to a render box's bounds, so this necessarily changes layout: buttons still paint 40x40, but a toolbar row is 48px tall instead of 40, the colour palette wraps to fewer swatches per row, and an editable checklist row is 48px tall and indents 48px instead of 32. A read-only checklist and the viewer are unaffected. Nothing paints differently — only spacing. Adjust MinimumTapTarget.minSize at a call site if you need the old density.
• The blockquote rule uses BorderDirectional, so it mirrors to the right in RTL documents instead of always sitting on the left.

Added #

• QuillKitEditor.onOpenSearch. Ctrl/Cmd+F was bound to a no-op action that reported the key as handled, so a host app's own find shortcut died whenever the editor had focus. With no callback the binding is omitted entirely and the key propagates.
• ==/hashCode on QuillKitStrings (an inherited-widget payload that previously forced every toolbar item to rebuild on any ancestor rebuild), and ==/hashCode/copyWith on EditorBehavior and EditorAppearance. Changing behavior at runtime now re-issues the IME configuration.

Changed #

• editor.dart and toolbar.dart now export the types their own signatures expose. Neither was usable standalone: toolbar.dart could not name QuillKitController, the required type of QuillKitToolbar.controller, and editor.dart could not name Document or Attribute.
• updateSelection's ChangeSource argument is now honoured instead of ignored: only a local selection change clears the pending style, so a remote or history-driven caret move no longer cancels a pending format.
• Removed the unused flutter_localizations dependency, which pulled intl into every consumer for nothing.

Initial release.

• Delta-compatible, pure-Dart document model: attribute registry, node tree, undo/redo history, edit rules, search, plain-text extraction; unknown attributes and embeds survive load/save round-trips.
• QuillKitController: selection, insert/format/indent commands, toggle semantics with pending styles, history grouping, per-instance EditorScope services (clipboard, link launcher) — no global state.
• QuillKitEditor: IME input, keyboard shortcuts, markdown-style typing autoformat, URL auto-linking, selection handles and context menu, placeholder text, read-only mode with tappable checklists.
• QuillKitViewer: a genuinely stateless, controller-free read-only renderer with optional selection, link taps, and checkbox taps.
• EditorExtension API — every built-in format ships as an extension, with basic(), standard(), and full() presets; custom attributes, edit rules, embed renderers, toolbar items, and shortcuts register per instance.
• Declarative QuillKitToolbar driven by extension-contributed items (or an explicit items: list), wrap and scroll layouts, group dividers.
• Theming via QuillKitTheme / QuillKitThemeData: partial themes merge over defaults derived from the ambient Material theme; the editor and viewer share one style-resolution path.
• Focused entrypoints: document.dart (server-safe model), editor.dart, toolbar.dart, plus the all-in flutter_quill_kit.dart.
• Correct tri-state text direction with separate LTR and RTL toggles.
• Localizable toolbar strings (QuillKitStrings / QuillKitStringsScope).
