Methods

build(BuildContext context) → Widget: As the widget builds, the HTML data is processed into a tree of StyledElements, which are then parsed into an InlineSpan tree that is then rendered to the screen by Flutter
override
createElement() → StatelessElement: Creates a StatelessElement to manage this widget's location in the tree.
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
parseTree(RenderContext context, StyledElement tree) → InlineSpan: parseTree converts a tree of StyledElements to an InlineSpan tree.
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode: Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String: A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.

Operators

operator ==(Object other) → bool: The equality operator.

Static Methods

lexDomTree(Element html, List<CustomRenderMatcher> customRenderMatchers, List<String> tagsList, BuildContext context, HtmlParser parser) → StyledElement: lexDomTree converts a DOM document to a simplified tree of StyledElements.
parseCss(String data) → StyleSheet: parseCss converts a string of CSS to a CSS stylesheet using the dart csslib library.
parseHTML(String data) → Element: parseHTML converts a string of HTML to a DOM element using the dart html library.
processTree(StyledElement tree, double devicePixelRatio) → StyledElement: processTree optimizes the StyledElement tree so all BlockElements are on the first level, redundant levels are collapsed, empty elements are removed, and specialty elements are processed.
styleTree(StyledElement tree, Element htmlData, Map<String, Style> style, OnCssParseError? onCssParseError) → StyledElement: styleTree takes the lexed StyleElement tree and applies external, inline, and custom CSS/Flutter styles, and then cascades the styles down the tree.
