Climbers aiming for the top will not be intoxicated by a certain footprint along the way. In the world of code farmers, the beautiful application experience comes from the programmer's handling of details and the realm of self-requirements. Young people are also busy One of the busy code farmers, every day and every week, will leave some footprints. It is the content of these creations. There is a kind of persistence. I don’t know why. If you are confused, you might as well take a look at the track of the code farmers.
The effect of this article is as follows:
1 The core code is to obtain the parent window size through LayoutBuilder
LayoutBuilder(builder: (BuildContext context, BoxConstraints constraints) {
double maxWidth = constraints.maxWidth;
double minWidth = constraints.minWidth;
double maxHeight = constraints.maxHeight;
double minHeight = constraints.minHeight;
if(maxWidth>400) {
return buildRow();
}
return buildColumn();
},)
2 All code implementation
class LayoutBuilderPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: LayoutBuilder(
builder: (BuildContext context, BoxConstraints constraints) {
double maxWidth = constraints.maxWidth;
double minWidth = constraints.minWidth;
double maxHeight = constraints.maxHeight;
double minHeight = constraints.minHeight;
if (maxWidth > 400) {
return buildRow();
}
return buildColumn();
},
),
),
);
}
Widget buildRow() {
return Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(onPressed: () {
}, child: Text("右侧按钮")),
SizedBox(
width: 60,
),
ElevatedButton(onPressed: () {
}, child: Text("左侧按钮")),
],
);
}
Widget buildColumn() {
return Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
ElevatedButton(onPressed: () {
}, child: Text("右侧按钮")),
SizedBox(
height: 60,
),
ElevatedButton(onPressed: () {
}, child: Text("左侧按钮")),
],
);
}
}
If you are confused, you might as well come here to share every day, and then accumulate
more Widget applications. The editor has summarized them in the book.
