Can we highlight multiple lines as specified?

[GreenLim]

In certain scenarios, I would like to highlight specific lines, for example, if a line contains particular information, highlighting can provide better prompts for the user. However, I haven’t found an available API for this. How can I achieve this requirement?

You can use this editor.

It provides a decoration API in the controller that can be used to highlight a line:

controller.setGitDiffDecorations(
  addedRanges: [(int startLine, int endLine), (int startline, int endLine), ... etc],
  removedRanges: [same pattern as above],
  modifiedRanges: [same pattern as above],
  addedColor: const Color(0xFF4CAF50),
  removedColor: const Color(0xFFE53935),
  modifiedColor: const Color(0xFF2196F3),
)

Also there's another API to scroll to a specific line:
controller.scrollToLine(int line)

Both of these provide a better line/lines highlighting.
