sized_box_for_whitespace
Use a 'SizedBox' to add whitespace to a layout.
Description
#
The analyzer produces this diagnostic when a Container is created using
only the height and/or width arguments.
Example
#
The following code produces this diagnostic because the Container has
only the width argument:
dart
import 'package:flutter/material.dart';
Widget buildRow() {
return Row(
children: <Widget>[
const Text('...'),
Container(
width: 4,
child: Text('...'),
),
const Expanded(
child: Text('...'),
),
],
);
}
Common fixes
#Replace the Container with a SizedBox of the same dimensions:
dart
import 'package:flutter/material.dart';
Widget buildRow() {
return Row(
children: <Widget>[
Text('...'),
SizedBox(
width: 4,
child: Text('...'),
),
Expanded(
child: Text('...'),
),
],
);
}
