The Flutter Sliders package is written natively in Dart for creating highly interactive and UI-rich slider widgets for filtering purposes in Flutter applications.
This library is used to create three different types of sliders, namely slider, range slider, and range selector. All these sliders have a rich set of features such as support for both numeric and date values, tooltip, labels, and ticks. The range selector latter accepts any kind of child including Charts.

-
Numeric and date support - Select numeric and date value. For date, support is provided up to the 'Seconds' interval.
-
Labels - Render labels for the date and numeric ranges with an option to customize formats based on the requirement.
-
Ticks and dividers - Show ticks and dividers based on the interval. Also, enable minor ticks between the ticks to indicate the selected values. These options show the selected range in a more intuitive way for the end users.
-
Tooltip - Render tooltip to show the selected value clearly. It is also possible to customize the format of the text shown in the tooltip.
-
Thumb icon support - Accepts custom widgets like icon or text inside the thumb.
-
Discrete selection - Provides an option for selecting only discrete numeric and date values.
-
Highly customizable - In addition to the built-in rich set of features, fully customize the control easily using the wide range of provided options.
-
Orientation - Supports both horizontal and vertical orientations.
-
Inversed vertical slider - Provides an option to change the minimum and maximum positions of the vertical slider.
Range slider supports all the above-mentioned features of the slider in addition to:
-
Orientation - Supports both horizontal and vertical orientations.
-
Inversed vertical range slider - Provides an option to change the minimum and maximum positions of the vertical range slider.
-
Drag mode - Various dragging options are available to control thumb dragging. The available options are
onThumb,betweenThumbs, andboth. -
Interval selection - Allows users to select a particular interval by tapping or clicking in it. Both thumbs will be moved to the current interval with animation.
Range selector supports all the above-mentioned features(except orientation and inversed slider) of the range slider in addition to:
-
Child support - Add a child of any type inside the range selector. It is also possible to add Charts. With the built-in integration, range selector is smart enough to handle features like segment selection or zooming of a chart based on the selected range in the range selector. Similar to the range slider, it also supports both numeric and date values.
-
Deferred update - Provides an option to defer range updates, allowing you to control when dependent components are updated while thumbs are being dragged continuously.
