Features #

  • The ExpandableSlider can have two status: shrunk and expanded.
  • When shrunk, ExpandableSlider behaves just like a Flutter's discrete Slider.
  • When expanded, ExpandableSlider will always have visible divisions whose spacing will always be enough for the user to move the slider thumb between divisions easily.
  • Customizable min, max, and value change between divisions.
  • Customizable expansion, shrinkage and expanded scrolling animations.
  • Expansion can be toggled with a long press, a scale gesture, or a double tap.
  • Just like Flutter's Slider, the appearance can be fully customized with SliderTheme and SliderThemeData.

Usage #

This package exposes an ExpandableSlider stateful widget for you to use wherever you want, just like a regular Slider.

    Widget build(BuildContext context) => ExpandableSlider(
        value: myValue,
        onChanged: (newValue) => setState(() => myValue = newValue),
        min: 0,
        max: 50,
        estimatedValueStep: 5,
      );

By default, the expansion will be toggled with either a long press on the slider or a scale gesture. Check out the example app in the project repository to find out more.
