sized_ box_ for_ whitespace
SizedBox
for whitespace.
Details
#Use SizedBox
to add whitespace to a layout.
A
Container
is a heavier Widget than a
SizedBox
, and as bonus,
SizedBox
has a
const
constructor.
BAD:
Widget buildRow() {
return Row(
children: <Widget>[
const MyLogo(),
Container(width: 4),
const Expanded(
child: Text('...'),
),
],
);
}
GOOD:
Widget buildRow() {
return Row(
children: const <Widget>[
MyLogo(),
SizedBox(width: 4),
Expanded(
child: Text('...'),
),
],
);
}
