swipe_action_cell

A Flutter list-cell widget with asymmetric swipe semantics — right swipe increments a value progressively, left swipe commits a destructive or reveal action.

Features

• Asymmetric swipe model — right swipe is progressive (increment/counter), left swipe is intentional (delete/archive/reveal)
• Spring-based physics — natural feel with configurable spring stiffness and damping, not fixed-duration animations
• Built-in undo — 5-second undo window before a destructive action fires, cancelable programmatically
• Reveal mode — left swipe slides open a panel of 1–3 tappable action buttons
• Multi-zone swipes — up to 4 distinct threshold zones per direction, each with its own visual and callback
• Zero-config templates — six prebuilt factory constructors (.delete, .archive, .favorite, .checkbox, .counter, .standard) work out of the box
• Accessibility and RTL — semantic labels, keyboard navigation, and direction-adaptive swipe semantics for right-to-left layouts
• Consumer testing utilities — SwipeTester, SwipeAssertions, MockSwipeController, and SwipeTestHarness for deterministic widget tests

Quick Start

import 'package:swipe_action_cell/swipe_action_cell.dart';

  child: const ListTile(title: Text('Left swipe to delete')),
  onDeleted: () => print('Deleted!'),
)

Configuration Reference

Parameter	Type	Default	Description
child	Widget	required	The list item widget displayed in the cell
leftSwipeConfig	LeftSwipeConfig?	null	Left-swipe behavior (auto-trigger or reveal mode). null disables left swipe
rightSwipeConfig	RightSwipeConfig?	null	Right-swipe progressive behavior. null disables right swipe
controller	SwipeController?	null	External controller for programmatic open/close/undo
visualConfig	SwipeVisualConfig?	null	Background builders, clip behavior, border radius
gestureConfig	SwipeGestureConfig?	null	Activation threshold, direction lock angle
animationConfig	SwipeAnimationConfig?	null	Spring stiffness, damping, mass
feedbackConfig	SwipeFeedbackConfig?	null	Haptic and audio patterns at swipe milestones
undoConfig	SwipeUndoConfig?	null	Undo window duration and callbacks
paintingConfig	SwipePaintingConfig?	null	Custom painter and decoration hooks
enabled	bool	true	Disables all gesture recognition when false
semanticConfig	SwipeSemanticConfig?	null	Accessibility labels and announcements

LeftSwipeConfig

Parameter	Type	Default	Description
mode	LeftSwipeMode	required	.autoTrigger fires callback; .reveal opens action panel
actions	List<SwipeAction>	[]	Action buttons shown in reveal mode (1–3 items)
actionPanelWidth	double?	null	Panel width in logical pixels; auto-calculated when null
postActionBehavior	PostActionBehavior	.snapBack	What happens after auto-trigger fires
enableHaptic	bool	false	Haptic feedback at activation threshold

RightSwipeConfig

Parameter	Type	Default	Description
stepValue	double	1.0	Amount added on each successful right swipe
maxValue	double	infinity	Upper bound for the cumulative value
overflowBehavior	OverflowBehavior	.clamp	What happens when maxValue is reached
showProgressIndicator	bool	false	Renders a persistent progress bar
onSwipeCompleted	ValueChanged<double>?	null	Called after each successful swipe with the new value
enableHaptic	bool	false	Haptic feedback at activation threshold

swipe_action_cell vs flutter_slidable

Feature	swipe_action_cell	flutter_slidable
Swipe model	Asymmetric — right = progressive, left = intentional	Symmetric — both sides show action panels
Built-in undo	✅ 5-second undo window before destructive callback	❌ Must implement manually with DismissiblePane
Animation physics	Spring-based (SpringSimulation) — natural feel	Fixed-duration Tween — linear/curve based
Right-swipe behavior	Progressive counter/value increment with real-time tracking	Reveal action panel (same as left swipe)
Prebuilt templates	✅ Six zero-config constructors	❌ Manual configuration required
Consumer testing	✅ SwipeTester, SwipeAssertions, MockSwipeController	❌ No dedicated testing utilities
Multi-zone swipes	✅ Up to 4 zones per direction	❌ Single threshold only
Reveal motion	Fixed-position panel reveal	Animated panel with DrawerMotion, ScrollMotion, etc.
Custom extent ratio per action	❌ Shared panel width	✅ Per-action extentRatio
