val_latex_flutter 0.1.1

val_latex_flutter: ^0.1.1 copied to clipboard

Requires val_latex 0.1.1, with everything it adds and fixes (TeX and LaTeX commands, packages, tikzcd, prooftree, robustness limits, scripts in other languages, glyph fallbacks).

Changed #

• Math.tex and MathSpan no longer parse as streaming by default: a formula on its own is complete, so an unfinished command or group at its end (x + \frac{a}{) shows its error instead of being hidden. For text still arriving, pass parseOptions: ParseOptions(streaming: true) or use MathText(streaming: true). The flutter_math_fork compatibility layer does the same.
• MathText.markdown is on by default: LLM replies are Markdown, so code spans and blocks are left as text. Pass markdown: false for plain text that uses backticks, ~~~ or <!--.
• MathText parses with its own streaming flag: a finished message now shows an error for an unfinished command (\fo) instead of hiding it.

Added #

• MathText.spacedDollars: accept $ x + y $ with spaces inside.
• \leqno numbers are painted on the left.
• \reflectbox: reflected text runs are painted mirrored.

First release.

val_latex_flutter renders LaTeX math in Flutter, using the val_latex engine.

Added #

• Math.tex — a formula as a widget, sized and coloured by the text style; display mode with equation numbers at the margin.
• MathText — text with $…$ and $$…$$ formulas in it, wrapping formulas with the words; safe for streaming text.
• MathSpan — inline math in Text.rich, on the text baseline.
• Wrapping — display formulas break to the width; MathOverflow scroll, shrink or clip for what cannot break. Baselines are reported in every case.
• Interaction — onTap, onLongPress, onHover, animated highlights, selection in a SelectionArea that copies LaTeX (copyFormat), and keyboard navigation (focusable).
• Accessibility — screen readers hear formulas spoken and move through them part by part; the bold-text setting is respected.
• MathTheme — colours, fonts, fallback fonts and styles per \htmlClass name.
• MathPainter — draw a layout on any canvas.
• Caching — MathCache shares parses and layouts between widgets; layoutInBackground lays long formulas out in a worker isolate.
• flutter_math_compat.dart — a drop-in replacement for package:flutter_math_fork/flutter_math.dart.
• Latin Modern text fonts bundled for \text{…}.
• Licence page — the third-party notices of this package and of val_latex appear on Flutter's licence page with no setup (registerValLatexLicenses).
