Example of how to create a slider widget in Flutter:
import 'package:flutter/material.dart';
class SliderExample extends StatefulWidget {
@override
_SliderExampleState createState() => _SliderExampleState();
}
class _SliderExampleState extends State<SliderExample> {
double _mysliderValue = 0.0;
@override
Widget build(BuildContext context) {
return Column(
children: <Widget>[
Slider(
value: _mysliderValue,
min: 0.0,
max: 100.0,
divisions: 100,
label: '$_mysliderValue',
onChanged: (double newValue) {
setState(() {
_mysliderValue = newValue;
});
},
),
Text('Slider Value: $_mysliderValue'),
],
);
}
}
This creates a Slider
widget with a range of 0 to 100 and a Text
widget that displays the current value of the slider. The onChanged
callback is used to update the state of the _sliderValue
variable and rebuild the widget tree to reflect the changes.
You can customize the look and feel of the slider by using different properties like activeColor
, inactiveColor
, min
, max
, divisions
, label
, etc. You can also customize the thumb shape of the slider using thumbShape
and thumbColor
properties.
You can also customize the value labels of the slider using valueIndicatorShape
and valueIndicatorColor
properties. You can also add a semantic label to the slider using semanticFormatterCallback the property.
