Markdown class

Core Markdown rendering widget for displaying formatted text in Arcane Flutter applications.

This stateless widget renders Markdown content using the GptMarkdown package, customized with Arcane-specific components for enhanced UI integration. It supports a wide range of Markdown elements including code blocks, tables, images, links, lists, and LaTeX math, all styled according to ArcaneTheme. Designed for efficient rendering in performance-sensitive contexts like FillScreen or SliverScreen, it avoids unnecessary rebuilds by leveraging const constructors and stateless design. Use within Section for modular content sections or BasicCard for contained, scrollable markdown views.

Key features:

  • Comprehensive support for Markdown syntax with Arcane-styled components (e.g., StaticTable for tables, HoverCard for links).
  • Custom link handling with hover previews and external URL launching.
  • Inline and block-level components for rich text rendering.
  • Performance optimized: Single-pass rendering with no state management overhead; suitable for large documents.
  • Integrates with Gesture for interactive elements and ArcaneTheme for consistent theming.

Usage example:

Markdown('## Heading\nThis is *italic* text with a [link](https://example.com).')
