Fluid Slider for Flutter

Inspired by a dribbble by Virgil Pana.

A fluid design slider that works just like the Slider material widget.

Used to select from a range of values.

Installation

Just add the package to your dependencies in the pubspec.yaml file:

dependencies:
  flutter_fluid_slider: ^0.0.1

Basic Usage

Place the FluidSlider in your widget tree.

FluidSlider(
  value: _value,
  onChanged: (double newValue) {
    setState(() {
      _value = newValue;
    });
  },
  min: 0.0,
  max: 100.0,
),

• Properties

• value : [Required] The currently selected value for this slider. The slider’s thumb is drawn at a position that corresponds to this value.
  
• min : The minimum value the user can select. Defaults to 0.0. Must be less than or equal to max.
  
• max : The maximum value the user can select. Defaults to 1.0. Must be less than or equal to min.
  
• start : The widget to be displayed as the min label. For eg: an Icon can be displayed. If not provided the min value is displayed as text.
  
• end : The widget to be displayed as the max label. For eg: an Icon can be displayed. If not provided the max value is displayed as text.
  
• onChanged : [Required] Called during a drag when the user is selecting a new value for the slider
  by dragging.
  • The slider passes the new value to the callback but does not actually change state until the parent widget rebuilds the slider with the new value.
    
  • If null, the slider will be displayed as disabled.
    
• onChangeStart : Called when the user starts selecting a new value for the slider. The value passed will be the last value that the slider had before the change began.
  
• onChangeEnd : Called when the user is done selecting a new value for the slider.
  
• labelsTextStyle : The styling of the min and max text that gets displayed on the slider. If not provided the ancestor Theme‘s accentTextTheme text style will be applied.
  
• valueTextStyle : The styling of the current value text that gets displayed on the slider. If not provided the ancestor Theme‘s textTheme.title text style with bold will be applied .
  
• sliderColor : The color of the slider. If not provided the ancestor Theme‘s primaryColor will be applied.
  
• thumbColor : The color of the thumb. If not provided the Colors.white will be applied.
