HighlightedText

A Flutter widget that provides a way to find and highlight specific text patterns within a body of text. It also offers tappable interactions for highlighted text segments.

• Custom Styling: Apply your own text style to the highlighted parts for a unique look.

  • Utilize dotAll for broader regular expression matching
