Wrap Two Fields In A Row In Flutter
Introduction
When building a form in Flutter, you often need to arrange multiple fields in a row. This can be achieved using the Row widget, which is a part of the Flutter Material library. In this article, we will explore how to wrap two fields in a row using the Row widget.
Using the Row Widget
The Row widget is a simple way to arrange multiple children in a horizontal row. To use it, you need to wrap your fields in a Row widget and specify the children you want to arrange in a row.
Here is an example of how to use the Row widget to wrap two fields in a row:
import 'package:flutter/material.dart';
class MyForm extends StatefulWidget {
@override
_MyFormState createState() => _MyFormState();
}
class _MyFormState extends State<MyForm> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Wrap Two Fields in a Row'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Form(
child: Column(
children: [
Row(
children: [
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 1',
border: OutlineInputBorder(),
),
),
),
SizedBox(width: 16),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
),
],
),
),
),
);
}
}
In this example, we use the Row widget to wrap two TextField widgets. We also use the Expanded widget to make sure both fields take up an equal amount of space in the row.
Using the Wrap Widget
Another way to wrap two fields in a row is to use the Wrap widget. The Wrap widget is a more flexible way to arrange children in a row or column.
Here is an example of how to use the Wrap widget to wrap two fields in a row:
import 'package:flutter/material.dart';
class MyForm extends StatefulWidget {
@override
_MyFormState createState() => _MyFormState();
}
class _MyFormState extends State<MyForm> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Wrap Two Fields in a Row'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Form(
child: Column(
children: [
Wrap(
spacing: 16,
children: [
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 1',
border: OutlineInputBorder(),
),
),
),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
),
],
),
),
),
);
}
}
In this example, we use the Wrap widget to wrap two TextField widgets. We also use the spacing property to specify the amount of space between the fields.
Using the Row and Expanded Widgets Together
You can also use the Row and Expanded widgets together to wrap two fields in a row. This is useful when you want to make sure both fields take up an equal amount of space in the row.
Here is an example of how to use the Row and Expanded widgets together to wrap two fields in a row:
import 'package:flutter/material.dart';
class MyForm extends StatefulWidget {
@override
_MyFormState createState() => _MyFormState();
}
class _MyFormState extends State<MyForm> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Wrap Two Fields in a Row'),
),
body: Padding(
padding: const EdgeInsets.all(16.0),
child: Form(
child: Column(
children: [
Row(
children: [
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 1',
border: OutlineInputBorder(),
),
),
),
SizedBox(width: 16),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
),
],
),
),
),
);
}
}
In this example, we use the Row widget to wrap two TextField widgets. We also use the Expanded widget to make sure both fields take up an equal amount of space in the row.
Conclusion
In this article, we explored how to wrap two fields in a row using the Row widget. We also discussed how to use the Wrap widget and the Row and Expanded widgets together to achieve the same result. By using these widgets, you can easily arrange multiple fields in a row and make sure they take up the right amount of space.
Example Use Cases
Here are some example use cases for wrapping two fields in a row:
- Creating a form with two fields that need to be arranged in a row.
- Building a layout with multiple fields that need to be arranged in a row.
- Creating a UI with two fields that need to be arranged in a row.

decoration: InputDecoration(
labelText: 'Field 1',
border: OutlineInputBorder(),
),
),
),
SizedBox(width: 16),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
)
Q3: How do I use the Wrap widget to wrap two fields in a row?
A3: To use the Wrap widget to wrap two fields in a row, you need to wrap your fields in a Wrap widget and specify the children you want to arrange in a row. Here is an example:
Wrap(
spacing: 16,

),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
)
Q4: How do I use the Row and Expanded widgets together to wrap two fields in a row?
A4: To use the Row and Expanded widgets together to wrap two fields in a row, you need to wrap your fields in a Row widget and use the Expanded widget to make sure both fields take up an equal amount of space in the row. Here is an example:

children: [
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 1',
border: OutlineInputBorder(),
),
),
),
SizedBox(width: 16),
Expanded(
child: TextField(
decoration: InputDecoration(
labelText: 'Field 2',
border: OutlineInputBorder(),
),
),
),
],
)
Q5: What are some common use cases for wrapping two fields in a row?
A5: Some common use cases for wrapping two fields in a row include:
- Creating a form with two fields that need to be arranged in a row.
- Building a layout with multiple fields that need to be arranged in a row.
- Creating a UI with two fields that need to be arranged in a row.
Q6: How do I handle cases where the fields are not equal in size?
A6: If the fields are not equal in size, you can use the Flexible widget instead of the Expanded widget. The Flexible widget allows you to specify a flex value for each child, which determines how much space it will take up in the row.
Q7: Can I use the Row widget to wrap more than two fields in a row?
A7: Yes, you can use the Row widget to wrap more than two fields in a row. Simply add more children to the Row widget and they will be arranged in a row.
Q8: Can I use the Wrap widget to wrap more than two fields in a row?
A8: Yes, you can use the Wrap widget to wrap more than two fields in a row. Simply add more children to the Wrap widget and they will be arranged in a row.
Q9: How do I handle cases where the fields are too wide to fit in the row?
A9: If the fields are too wide to fit in the row, you can use the Wrap widget with the spacing property set to a negative value. This will cause the fields to wrap to the next line when they reach the edge of the row.
Q10: Can I use the Row and Wrap widgets together?
A10: Yes, you can use the Row and Wrap widgets together. However, this is not recommended as it can lead to complex and hard-to-debug layouts.
Conclusion
Wrapping two fields in a row is a common task in Flutter development. By using the Row widget, the Wrap widget, and the Row and Expanded widgets together, you can easily arrange multiple fields in a row and make sure they take up the right amount of space.
