withDividerInBetween method

List<Widget> withDividerInBetween({ Color? color, double? height, double? thickness, double? indent, double? endIndent, })

withDividerInBetween Returns a new list with dividers between each widget.

The divider's color, height, thickness, indent, and endIndent can be customized.

If the list is empty, an empty list is returned.

Example:

List<Widget> widgets = [Widget1(), Widget2(), Widget3()];
List<Widget> separatedWidgets = widgets.withDividerInBetween(
  color: Colors.grey,
  height: 1.0,
  thickness: 1.0,
  indent: 10.0,
  endIndent: 10.0,
);

Implementation

List<Widget> withDividerInBetween({
  Color? color,
  double? height,
  double? thickness,
  double? indent,
  double? endIndent,
}) {
  List<Widget> separatedList = <Widget>[];
  final divider = Divider(
    color: color,
    height: height,
    thickness: thickness,
    indent: indent,
    endIndent: endIndent,
  );

  for (var i = 0; i < length; i++) {
    separatedList.add(this[i]);
    ifNotLast(i) ? separatedList.add(divider) : null;
  }

  return separatedList;
