Slider in Flutter | Flutter Slider with Example

In Flutter, the Slider widget is used to create a slider input that allows users to select a value within a specified range. Here’s an example of how you can use the Slider widget in Flutter:

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:rt_assignments/line_chart.dart';
import 'package:rt_assignments/slider_example.dart';

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {

  @override
  Widget build(BuildContext context) {
    
    return Scaffold(
            appBar: AppBar(
              title: Text('Flutter Example'),
            ),
      body: SliderExample()
    );
  }

Now

import 'package:flutter/material.dart';

class SliderExample extends StatefulWidget {
  @override
  _SliderExampleState createState() => _SliderExampleState();
}

class _SliderExampleState extends State<SliderExample> {
  double _sliderValue = 50.0;
  double _sliderValue1 = 0.0;
  double _sliderValue2 = 50.0;
  int _divisions = 5;
  double _minValue = 0.0;
  double _maxValue = 100.0;

  @override
  Widget build(BuildContext context) {
    return Column(
      mainAxisAlignment: MainAxisAlignment.center,
      children: [
//I
        Text('Slider Value: $_sliderValue'),
        SizedBox(height: 20),
        Slider(
          value: _sliderValue,
          min: 0,
          max: 100,
          onChanged: (value) {
            setState(() {
              _sliderValue = value;
            });
          },
        ),

//II
        Text('Slider Value: $_sliderValue1'),
        SizedBox(height: 20),
        Slider(
          value: _sliderValue1,
          min: 0,
          max: 100,
          divisions: _divisions,
          onChanged: (value) {
            setState(() {
              _sliderValue1 = value;
            });
          },
        ),
//III
        Text('Slider Value: $_sliderValue2'),
        SizedBox(height: 20),
        Slider(
          value: _sliderValue2,
          min: _minValue,
          max: _maxValue,
          onChanged: (value) {
            setState(() {
              _sliderValue2 = value;
            });
          },
        ),
      ],
    );
  }
}
