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.
