MarkdownHighlighter class final

A SyntaxHighlighter driven by Grammars.

The caller supplies the exact set of languages to support, so only the grammars named here are retained; every other language is dropped by tree-shaking.

Methods

backgroundFor(String? language) → Color?

The background color to use for language's code block, or null to keep the ambient surface color.

override

baseStyleFor(String? language, TextStyle fallback) → TextStyle

The base style for language's code, derived from fallback (the code block's monospace style). Used to apply the theme's default foreground so untokenized code stays legible on the theme background.

override

highlight(String code, String? language, TextStyle baseStyle) → List<InlineSpan>

Returns the spans for code, tagged for language. Implementations must preserve text exactly: the concatenation of the returned spans' text must equal code, so selection and copy stay aligned. baseStyle is the code block's base (monospace) style, already applied to the enclosing span.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.
