createGroupAnnotation method

GroupAnnotation createGroupAnnotation({ required String id, required String title, required Offset position, required Size size, Color color = Colors.blue, })

• title: Display title shown in the group header
• position: Top-left position of the group
• size: Width and height of the group (minimum 100x60)
• color: Color for the group header and background tint

GroupAnnotation createGroupAnnotation({
  required String id,

}) {
  final groupAnnotation = GroupAnnotation(
    id: id,
    position: position,

    title: title,
    color: color,
  );
