OverrideHeader class

Override the Header parameter. First of all you have to make it clear that this is feasible, otherwise please don't use it.

Properties

clamping → bool
Hold to keep the Scrollable from going out of bounds.
finalinherited
frictionFactor → FrictionFactor?
Friction factor when list is out of bounds. See BouncingScrollPhysics.frictionFactor.
finalinherited
hapticFeedback → bool
Whether to enable haptic feedback.
finalinherited
hashCode → int
The hash code for this object.
no setterinherited
Header that needs to be overwritten.
final
hitOver → bool
Hit boundary over. When the Scrollable scrolls by itself, is it out of bounds. When clamping is false, it takes effect.
finalinherited
horizontalFrictionFactor → FrictionFactor?
Horizontal friction factor when list is out of bounds. See BouncingScrollPhysics.frictionFactor.
finalinherited
horizontalReadySpringBuilder → SpringBuilder?
Horizontal spring effect when the mode is IndicatorMode.ready.
finalinherited
horizontalSpring → SpringDescription?
Horizontal spring effect when scrollable goes back.
finalinherited
infiniteHitOver → bool
Infinite scroll hits out of bounds. When the Scrollable scrolls by itself, whether the infinite scroll is out of bounds. When clamping is false, it takes effect.
finalinherited
infiniteOffset → double?
Infinite scroll trigger offset. The relative offset of the Scrollable from the bounds (>= 0) When null, no infinite scroll.
finalinherited
listenable → IndicatorStateListenable?
Indicator state listenable. Monitor state changes in real time.
finalinherited
maxOverOffset → double
Maximum overscroll offset, will no longer scroll. When double.infinity, no limit.
finalinherited
notifyWhenInvisible → bool
Notify when invisible. When IndicatorNotifier.offset < 0, scrolling will also trigger notification. This might have extra performance overhead, but it's very useful when you need it.
finalinherited
position → IndicatorPosition
The position of the indicator.
finalinherited
processedDuration → Duration
Task completion delay. IndicatorMode.processed duration of state.
finalinherited
readySpringBuilder → SpringBuilder?
Spring effect when the mode is IndicatorMode.ready.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
safeArea → bool
Whether to calculate the safe area.
finalinherited
secondaryCloseTriggerOffset → double
Secondary close trigger offset.
finalinherited
secondaryDimension → double?
Dimension of the second floor. The default value is ScrollMetrics.viewportDimension.
finalinherited
secondaryTriggerOffset → double?
Trigger offset for secondary. The indicator will expand and fill the scrollview area. Will not trigger when null.
finalinherited
secondaryVelocity → double
Secondary opening speed.
finalinherited
spring → SpringDescription?
Spring effect when scrollable goes back.
finalinherited
springRebound → bool
Whether the spring can rebound. Only works with readySpringBuilder.
finalinherited
triggerOffset → double
The offset of the trigger task.
finalinherited
triggerWhenReach → bool
Trigger immediately when reaching the triggerOffset.
finalinherited
triggerWhenRelease → bool
Over triggerOffset, the release triggers immediately.
finalinherited
triggerWhenReleaseNoWait → bool
Over triggerOffset, the release triggers immediately. No need to wait for task execution to complete, generally used for non-asynchronous events or external custom indicators.
finalinherited

Methods

build(BuildContext context, IndicatorState state) → Widget
Build indicator widget.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toString() → String
A string representation of this object.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
