如何在一个滑块上添加多个滑块？#Flutter

import 'package:flutter/material.dart';

class MultiSlider extends StatefulWidget {
  @override
  _MultiSliderState createState() => _MultiSliderState();
}

class _MultiSliderState extends State<MultiSlider> {
  double _sliderValue1 = 0.0;
  double _sliderValue2 = 0.5;

  @override
  Widget build(BuildContext context) {
    return Column(
      children: <Widget>[
        Slider(
          value: _sliderValue1,
          min: 0.0,
          max: 1.0,
          divisions: 10,
          label: _sliderValue1.round().toString(),
          onChanged: (double value) {
            setState(() {
              _sliderValue1 = value;
            });
          },
        ),
        Slider(
          value: _sliderValue2,
          min: 0.0,
          max: 1.0,
          divisions: 10,
          label: _sliderValue2.round().toString(),
          onChanged: (double value) {
            setState(() {
              _sliderValue2 = value;
            });
          },
        ),
      ],
    );
  }
}
