Line decorations can be used to highlight code changes (git diff), mark breakpoints, show coverage information, or any custom highlighting.

controller.addLineDecoration(LineDecoration(
  startLine: 10,
  endLine: 15,
  type: LineDecorationType.background,
  color: Colors.green.withOpacity(0.2),
));

Example - Git diff left border:

controller.addLineDecoration(LineDecoration(
  startLine: 10,
  endLine: 15,
  type: LineDecorationType.leftBorder,
  color: Colors.green,
  thickness: 3,
));
