paste_anything_editor 0.4.1

Rich text editor for Flutter web that pastes and copies Word, Excel, Google Docs, Markdown, HTML, tables, math formulas and images with formatting kept.

0.4.1

• Math default theme: when no seedColor / colorScheme is set, math UI uses a teal seed (PaeMathTheme.defaultSeedColor) so the keyboard and dialog match the standalone dialog look out of the box.
• Editor theming: PaeEditorTheme / PaeEditorLabels for border, copy / paste row, snackbar chrome and all toast strings; onNotify still replaces SnackBars entirely.
• LaTeX formatting guard: toolbar bold / size / font on a selected formula is blocked and shows a toast (cannotFormatFormula).
• Display math: $$…$$ / \[…\] keep a display flag through HTML ↔ Delta; embeds render with MathStyle.display when flagged.
• Wider $…$ detection (still skips currency like $5); matrix templates for pmatrix / bmatrix / vmatrix.
• Dialog polish: segmented tabs, clearer formula layout; shape knobs (dialogShape, dialogBorderSide, header icon, etc.).
• Fix: deactivated-ancestor assert when closing the standalone math dialog (safe FocusNode dispose + pop on next frame). Also: formula-only LaTeX editor no longer creates a [TabController] in dispose (lazy late final was the real crash).
• Example: one shared PaeMathTheme for the editor and the standalone dialog.
• Image paste remains opt-in via PaeEditorController(allowImagePaste: true) (default embeds as data: URIs; optional onImagePaste upload).

0.4.0

• The copy-paste logic moved to a new pure Dart package, paste_anything, for teams with their own editor. This package depends on it and re-exports it.
• Every public name now has the Pae prefix: PaeEditor, PaeEditorController, PaeQuillCodec, PaeMathKeyboard, PaeMathDialog, PaeMathTheme, PaeMathLabels, and so on. The old names still work but are deprecated and will be removed in 1.0.
• PaeEditorController implements PaeTarget and pastes through PaePaster.
• Breaking: insertImage now takes a PaeImage; the URL variant is insertImageUrl(url). insertImageBytes is deprecated.
• Clipboard helpers are now PaeClipboard (read, readText, writeHtml, writeText, waitForFocus); HTML cleanup is PaeHtml.normalize.
• Pasted HTML is also stripped of event handlers and javascript: links before conversion.
• Repository is now a pub workspace (packages/).

0.3.0

• Math keyboard: the toolbar math button now opens a docked MathKeyboard at the bottom of the screen. The editor keeps focus, so you can move the cursor and keep tapping symbols or formula templates. Toggle it with the same button or hide it from its header.
• RichHtmlEditor.mathInputMode: MathInputMode.keyboard (default) or MathInputMode.dialog (previous behavior).
• MathPanelTheme: keyboardHeight, keyboardMaxWidth, keyboardBorderRadius. MathPanelLabels: toolbarTooltip, keyboardTitle, formulasCategory, openLatexEditor, hideKeyboard.
• The package is now declared web-only on pub.dev.
• Simpler README.

0.2.0

• Fix: first "paste with formatting" after granting clipboard permission failed with NotAllowedError: Document is not focused. HTML, text and images are now read in a single Clipboard API call, and the read is retried once the page regains focus.
• New readClipboardText() and waitForDocumentFocus(); ClipboardSnapshot now carries text and isAvailable.
• Math dialog theming: MathPanelTheme (Material ThemeExtension, app-wide or per use, seedColor / colorScheme, every color, radius, size) and MathPanelLabels (all texts).
• MathInputDialog.show / MathInputPanel: theme, labels, symbolGroups, templates, showSymbolsTab, showFormulaTab.
• RichHtmlEditor: mathTheme, mathLabels; formula editing opens the formula tab only.
• Fix: MissingFlutterQuillLocalizationException when the app doesn't add FlutterQuillLocalizations.delegate; the editor now provides it (QuillLocalizationsScope).
• example/ is now a standalone Flutter web app (flutter run -d chrome).
• Docs: Flutter 3.44 needs flutter_quill >= 11.6.0.

0.1.0

• Initial release.
• RichHtmlEditor / RichHtmlEditorController: Quill editor that loads and saves HTML, with copy/paste toolbar.
• Rich paste from Word, Excel, Google Docs, web pages, code editors, HTML source and Markdown (colors, fonts, bold/italic/underline/strike, lists, headings, links, tables).
• Tables as editable block embeds.
• Math: Unicode symbol palette, LaTeX formulas rendered as equations, paste from KaTeX / MathJax / MathML / $..$ text, copy as HTML + LaTeX.
• Opt-in image paste (allowImagePaste) with upload callback or data: URI fallback; unsupported embeds render a placeholder instead of crashing.
