Scrollable position of a TextSpan within a RichText
问题 I have many TextSpan s in my RichText . I would like to scroll in a specific TextSpan , but for knowing the position I need the context. TextSpan is not a widget. So how can I get the TextSpan 's position? I can't use WidgetSpan because my Span s are pieces of the same sentence.
