build method
The final step in the chain. Converts the StyledElement tree, with its
attached Style
elements, into an InlineSpan
tree that includes
Widget/TextSpans that can be rendered in a RichText widget.
Implementation
@override
InlineSpan build(ExtensionContext context) {
return WidgetSpan(
child: IframeWidget(
extensionContext: context,
navigationDelegate: navigationDelegate,
),
);
}
