IndicatorController class - custom_refresh_indicator library

Constructors

IndicatorController({bool? refreshEnabled}): Creates CustomRefreshIndicator controller class
factory

Properties

direction → AxisDirection: The direction in which the list scrolls
no setter
dragDetails → DragUpdateDetails?: no setter
edge → IndicatorEdge?: Whether the pull to refresh gesture is triggered from the start of the list or from the end.
no setter
hasEdge → bool: Whether the edge was determined by the CustomRefreshIndicator widget.
no setter
hashCode → int: The hash code for this object.
no setterinherited
isArmed → bool: The user has dragged the pointer further than the distance declared by containerExtentPercentageToArmed or offsetToArmed (over the value of 1.0). Releasing the pointer in this state will trigger the onRefresh function.
no setter
isCanceling → bool: The function onRefresh has not been executed, and the indicator is hidding from its current value that is lower than 1.0 to 0.0.
no setter
isComplete → bool: OPTIONAL - Provide completeStateDuration argument to enable it. The onRefresh callback has completed and the pointer remains at value 1.0 for the specified duration.
no setter
isCompleted → bool: Whether this animation is stopped at the end.
no setterinherited
isDismissed → bool: Whether this animation is stopped at the beginning.
no setterinherited
isDragging → bool: The user starts scrolling/dragging the pointer to refresh. Releasing the pointer in this state will not trigger the onRefresh function. The controller value changes from 0.0 to 1.0.
no setter
isFinalizing → bool: The onRefresh function has been executed, and the indicator hides from the value 1.0 to 0.0.
no setter
isHorizontalDirection → bool: Whether list scrolls horrizontally
no setter
isIdle → bool: In this state, the indicator is not visible. No user action is performed. Value remains at 0.0.
no setter
isLoading → bool: The indicator is in its target value 1.0. The onRefresh function is triggered.
no setter
isRefreshEnabled → bool: Whether custom refresh indicator can change IndicatorState from idle to dragging
no setter
isScrollIdle → bool: No scrolling is underway.
no setter
isScrollingForward → bool: Scrolling is happening in the positive scroll offset direction.
no setter
isScrollingReverse → bool: Scrolling is happening in the negative scroll offset direction.
no setter
isSettling → bool: The user has released the indicator in the armed state. The indicator settles on its target value 1.0.
no setter
isVerticalDirection → bool: Whether list scrolls vertically
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scrollingDirection → ScrollDirection: The direction in which the user scrolls.
no setter
shouldStopDrag → bool: Should the dragging be stopped
no setter
side → IndicatorSide: The side of the scrollable on which the indicator should be displayed.
no setter
state → IndicatorState: Describes current CustomRefreshIndicator state
no setter
status → AnimationStatus: Provides the status of the animation: AnimationStatus.dismissed when the indicator state is IndicatorState.idle, and AnimationStatus.forward otherwise.
no setteroverride
value → double: Current indicator value / progress
no setteroverride

Methods

addListener(VoidCallback listener) → void: Calls the listener every time the value of the animation changes.
inherited
addStatusListener(AnimationStatusListener listener) → void: Calls listener every time the status of the animation changes.
inherited
clamp(double min, double max) → Animation<double>: Returns a ClampedAnimation that constrains the animation value of its parent within the given min and max range.

stopDrag() → void
toString() → String: A string representation of this object.
inherited
toStringDetails() → String: Provides a string describing the status of this object, but not including information about the object itself.
