Constructors

BarInteractionEvents.new({required bool isEnabled, SnapToBarConfig snapToBarConfig = const SnapToBarConfig(), Fuzziness fuzziness = const Fuzziness.zero(), void onTap(BarInteractionResult interactionResult)?, void onDoubleTap(BarInteractionResult interactionResult)?, void onDragStart(BarInteractionResult interactionResult)?, void onDrag(BarInteractionResult interactionResult)?, void onDragEnd(BarInteractionResult interactionResult)?, void onRawInteraction(BarInteractionResult interactionResult)?})

Properties

fuzziness → Fuzziness

Fuzziness increases the area of hit detection for a bar. Should ideally be used only if SnapToBarConfig is disabled.

final

hashCode → int

The hash code for this object.

no setter, inherited

isEnabled → bool

Set if interaction is enabled.

final, inherited

onDoubleTap → void Function(BarInteractionResult interactionResult)?

onDoubleTap is be called after a double tap gesture is detected.

final, inherited

onDrag → void Function(BarInteractionResult interactionResult)?

onDrag is called when the pointer location is updated for the pointer that started the drag gesture.

final, inherited

onDragEnd → void Function(BarInteractionResult interactionResult)?

onDragEnd is called when the pointer that triggered the drag gesture stop moving ending the drag gesture.

final, inherited

onDragStart → void Function(BarInteractionResult interactionResult)?

onDragStart is called when a pointer comes in contact with the screen and starts moving triggering a drag gesture.

final, inherited

onRawInteraction → void Function(BarInteractionResult interactionResult)?

onRawInteraction receives all types of interaction events.

final, inherited

onTap → void Function(BarInteractionResult interactionResult)?

onTap is be called after a tap gesture is completed. It is called right after onTapUp.

final, inherited

onTapDown → void Function(BarInteractionResult interactionResult)?

onTapDown is called when the pointer that will trigger a tap gesture comes in contact with the screen.

final, inherited

onTapUp → void Function(BarInteractionResult interactionResult)?

onTapUp is called when the pointer that will trigger a tap gesture stops making contact with the screen.

final, inherited

props → List<Object?>

The list of properties that will be used to determine whether two instances are equal.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

shouldHitTest → bool

no setter, inherited

snapToBarConfig → SnapToBarConfig

SnapToBarConfig determines the way interactions outside the boundary of the bar are handled by dictating how the interactions are interpreted.

final

stringify → bool?

If set to true, the toString method will be overridden to output this instance's props.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

onInteraction(BarInteractionResult interactionResult) → void

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
