Fluid Slider for Flutter

Awesome Flutter

Inspired by a dribbble by Virgil Pana.

enter image description here

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: ^1.0.2

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.
    • showDecimalValue
      : Whether to display the first decimal value of the slider value. Defaults to
      false
      .
    • mapValueToString
      : called with value for the String to be rendered in the slider's thumb. E.g. display roman integers as follows:
      dart
      FluidSlider(
      value:_val,
      min:1.0,
      max:5.0,
      onChanged:(){},
      mapValueToString: (double value){
      List romanNumerals=['I', 'II', 'III', 'IV', 'V'];
      return _romanNumerals[value.toInt() - 1];
      }
      )
      
      See example. If null the value is converted to String based on [showDecimalValue].
