An extension of the Flutter Material Slider to allow selection of a range of values via 2 thumbs.
A full explanation on how to build such Widget may be found on my blog:
You should ensure that you add the following dependency in your Flutter project.
dependencies:
flutter_range_slider: "^1.1.0"
You should then run flutter packages upgrade
or update your packages in IntelliJ.
In your Dart code, to use it:
import 'package:flutter_range_slider/flutter_range_slider.dart';
An example can be found in the example
folder. Check it out.
