Flutter有一个名为Slider的小部件，它几乎可以自定义所有属性，除了分隔属性，对于这一点，我们可以在Slider上面添加一个Container来实现分隔外观。
完整代码如下：
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const Box(),
);
}
}
class Box extends StatefulWidget {
const Box({super.key});
@override
State<Box> createState() => _BoxState();
}
void g() {}
class _BoxState extends State<Box> {
double sliderValue = 50;
@override
Widget build(BuildContext context) {
return SliderTheme(
data: SliderThemeData(
trackHeight: 80,
thumbShape: SliderComponentShape.noOverlay,
overlayShape: SliderComponentShape.noOverlay,
valueIndicatorShape: SliderComponentShape.noOverlay,
activeTrackColor: const Color.fromARGB(255, 9, 84, 146),
trackShape: const RectangularSliderTrackShape()),
child: Scaffold(
body: Center(
child: Stack(
alignment: Alignment.center,
children: [
SizedBox(
height: 250,
width: 80,
child: RotatedBox(
quarterTurns: 3,
child: ClipRRect(
borderRadius: const BorderRadius.all(Radius.circular(25)),
child: Slider(
onChanged: (value) {
setState(() {
sliderValue = value;
});
},
value: sliderValue,
min: 0,
max: 100,
divisions: 4,
),
),
),
),
SizedBox(
height: 250,
width: 80,
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Container(
height: 1,
width: 80,
color: Colors.white,
),
Container(
height: 1,
width: 80,
color: Colors.white,
),
Container(
height: 1,
width: 80,
color: Colors white,
),
],
),
),
],
))),
);
}
}
英文:
Flutter has Slider Widget which has almost all the properties that can be customized except for the divider property, for that we can add Container on top of Slider to give that separation appearance.
Complete Code : -
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const Box(),
);
}
}
class Box extends StatefulWidget {
const Box({super.key});
@override
State<Box> createState() => _BoxState();
}
void g() {}
class _BoxState extends State<Box> {
double sliderValue = 50;
@override
Widget build(BuildContext context) {
return SliderTheme(
data: SliderThemeData(
trackHeight: 80,
thumbShape: SliderComponentShape.noOverlay,
overlayShape: SliderComponentShape.noOverlay,
valueIndicatorShape: SliderComponentShape.noOverlay,
activeTrackColor: const Color.fromARGB(255, 9, 84, 146),
trackShape: const RectangularSliderTrackShape()),
child: Scaffold(
body: Center(
child: Stack(
