Flutter – How to add label to Divider widget

Flutter offers Divider widget but it is very simple one and doesn’t offer label. To add label text we need to use Row widget. I created the following widget which can be reused everywhere.

class DividerWithTextWidget extends StatelessWidget {
  final String text;
  DividerWithTextWidget({required this.text});

  @override
  Widget build(BuildContext context) {
    final line = Expanded(
        child: Container(
      margin: EdgeInsets.only(left: 10, right: 10),
      child: Divider(height: 20, thickness: 5),
    ));

    return Row(children: [line, Text(this.text), line]);
  }
}

I used the widget 3 times as follows.

return Scaffold(
    appBar: AppBar(
    title: Text(widget.title),
    ),
    body: ListView(
    children: [
        DividerWithTextWidget(text: "NAME"),
        Padding(child: nameField, padding: EdgeInsets.only(bottom: 20)),
        Padding(child: typeRow, padding: EdgeInsets.only(bottom: 20)),
        DividerWithTextWidget(text: "UNIT"),
        Padding(child: unitRow, padding: EdgeInsets.only(bottom: 20)),
        DividerWithTextWidget(text: "CATEGORY"),
        Padding(child: categoryRow, padding: EdgeInsets.only(bottom: 20)),
        Padding(
            child: parentCategoryRow, padding: EdgeInsets.only(bottom: 20)),
        _createOkCancelButton(),
    ],
    padding: EdgeInsets.all(10),
    ),
);

The result looks like the below.

I haven’t understood yet why Expanded is needed but Divider doesn’t appear without it. The view looks like this without Expanded widget.
