Get Started

Single Slider

A single slider

FlutterSlider(
  values: [300],
  max: 500,
  min: 0,
  onDragging: (lowerValue, upperValue) {
    _lowerValue = lowerValue;
    _upperValue = upperValue;
    setState(() {});
  },
)

to make slider Right To Left use rtl: true

 FlutterSlider(
  ...
  rtl: true,
  ...
)

Range Slider

A simple example of slider

FlutterSlider(
  values: [30, 420],
  rangeSlider: true,
  max: 500,
  min: 0,
  onDragging: (lowerValue, upperValue) {
    _lowerValue = lowerValue;
    _upperValue = upperValue;
    setState(() {});
  },
)

Customization

Handlers

You can customize handlers using handler and rightHandler properties.
width and height are required for custom handlers, so we use SizedBox as a wrapper

if you use rangeSlider then you should define rightHandler as well if you want to customize handlers

here there is a range slider with customized handlers and trackbars

FlutterSlider(
  ...
  handler: SizedBox(
    width: 20,
    height: 50,
    child: Container(
      child: Icon(
        Icons.view_headline,
        color: Colors.black54,
        size: 13,
      ),
      decoration: BoxDecoration(
          color: Colors.white,
          border:
              Border.all(color: Colors.black.withOpacity(0.12))),
    ),
  ),
  rightHandler: SizedBox(
    width: 20,
    height: 50,
    child: Container(
      child: Icon(
        Icons.view_headline,
        color: Colors.black54,
        size: 13,
      ),
      decoration: BoxDecoration(
          color: Colors.white,
          border:
              Border.all(color: Colors.black.withOpacity(0.12))),
    ),
  ),
  ...
)

Trackbars

FlutterSlider(
  ...
    activeTrackBarColor: Colors.redAccent,
    activeTrackBarHeight: 5,
    inactiveTrackBarHeight: 2,
    leftInactiveTrackBarColor: Colors.greenAccent.withOpacity(0.5),
  ...
)

Tooltips

FlutterSlider(
  ...
  tooltipTextStyle: TextStyle(fontSize: 17, color: Colors.white),
  tooltipBox: FlutterSliderTooltip(
    decoration: BoxDecoration(
      color: Colors.red.withOpacity(0.5),
    )
  ),
  ...
)

Controls

Jump

by default slider handlers move fluently, if you set jump to true, handlers will jump between intervals

FlutterSlider(
  ...
  jump: true,
  ...
)

divisions

The number of discrete divisions

FlutterSlider(
  ...
  divisions: 25,
  ...
)

Ignore Steps

if you configurations requires that some steps are not available, you can use ignoreSteps property.
this property accepts a simple class to define from and to ranges.

FlutterSlider(
  ...
    ignoreSteps: [
      SliderIgnoreSteps(from: 8000, to: 12000),
      SliderIgnoreSteps(from: 18000, to: 22000),
    ],
  ...
)

Tooltip Number Format

you can customize tooltip numbers by using NumberFormat class
here is an example

FlutterSlider(
  ...
  tooltipNumberFormat: intl.NumberFormat(),
  // tooltipNumberFormat: intl.compact(),
  ...
)

you can find more about NumberFormat

Touch Zone

You can control how big a handler's touch area could be. by default touch zone is 2
the range is between 1 to 5

FlutterSlider(
  ...
  touchZone: 2,
  ...
)

to see the touchable area for handlers you set displayTestTouchZone to true and test your slider

FlutterSlider(
  ...
  displayTestTouchZone: true,
  ...
)

disabled

to disable your slider, you can use disabled.

FlutterSlider(
  ...
  disabled: true,
  ...
)

rtl

FlutterSlider(
  ...
  rtl: true,
  ...
)

Events

There are 3 events

onDragStarted: fires when drag starts
onDragCompleted fires when drag ends
onDragging keeps firing when dragging

all three of above functions returns two double values. Lower Value and Upper Value

FlutterSlider(
  ...
  onDragging: (lowerValue, upperValue) {
    _lowerValue = lowerValue;
    _upperValue = upperValue;
    setState(() {});
  },
  ...
)
