See www.angelfire.com/al4/rcollins/style/fonts.html for a good description of fonts available between platforms and browsers.

PreprocessorOptions
Rgba
Rgba class for users that want to interact with a color as a RGBA value.
Token
A single token in the Dart language.
TokenChar
Tokenizer
TokenizerBase
The base class for our tokenizer. The hand coded parts are in this file, with the generated parts in the subclass Tokenizer.
TokenizerHelpers
Static helper methods.
TokenizerState
Tokenizer state to support look ahead for Less' nested selectors.
TokenKind
TopLevelIncludes
Expand all @include at the top-level the ruleset(s) associated with the mixin.

Functions

analyze(List<StyleSheet> styleSheets, {List<Message>? errors, PreprocessorOptions? options}) → void
Analyze the CSS file.
compile(dynamic input, {List<Message>? errors, PreprocessorOptions? options, bool nested = true, bool polyfill = false, List<StyleSheet>? includes}) → StyleSheet
Parse and analyze the CSS file.
parse(dynamic input, {List<Message>? errors, PreprocessorOptions? options}) → StyleSheet
Parse the input CSS style sheet into a tree. The input can be a String, or List<int> of bytes and returns a StyleSheet AST. The optional errors list will contain each error/warning as a Message.
parseSelectorGroup(dynamic input, {List<Message>? errors}) → SelectorGroup?
selector(dynamic input, {List<Message>? errors}) → StyleSheet
Parse the input CSS selector into a tree. The input can be a String, or List<int> of bytes and returns a StyleSheet AST. The optional errors list will contain each error/warning as a Message.
