Flutter – How to add label to Divider widget

eye-catchDart and Flutter

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});

  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)),
            child: parentCategoryRow, padding: EdgeInsets.only(bottom: 20)),
    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.
