expandable_slider

A Flutter slider that can be expanded to select values with more precision.

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.
