Properties
-
areItemsTheSame
→ ItemDiffUtil<
E> -
Called by the DiffUtil to decide whether two object represent the same Item.
For example, if your items have unique ids, this method should check their id equality.
finalinherited
- controller → ScrollController?
-
An object that can be used to control the position to which this scroll
view is scrolled.
final
-
A non-reorderable widget displayed at the bottom.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- header → Widget?
-
A non-reorderable widget displayed at the top.
final
- insertDuration → Duration
-
The duration of the animation when an item was inserted into the list.
finalinherited
-
itemBuilder
→ AnimatedItemBuilder<
Reorderable, E> -
Called, as needed, to build list item widgets.
finalinherited
-
items
→ List<
E> -
The data that this ImplicitlyAnimatedList should represent.
finalinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- liftDuration → Duration
-
The duration of the animation when a reorder has been initiated
by the Handle of the item.
final
-
onReorderFinished
→ ReorderFinishedCallback<
E> -
Called in response to when the dragged item has been released
and animated to its final destination. Here you should update
the underlying data in your model/bloc/database etc.
final
-
onReorderStarted
→ ReorderStartedCallback<
E> ? -
Called in response to when an item changed from normal to dragged
state and may be reordered.
final
- padding → EdgeInsetsGeometry?
-
The amount of space by which to inset the children.
final
- physics → ScrollPhysics?
-
How the scroll view should respond to user input.
final
- primary → bool?
-
Whether this is the primary scroll view associated with the parent
PrimaryScrollController.
final
- removeDuration → Duration
-
The duration of the animation when an item was removed from the list.
finalinherited
-
removeItemBuilder
→ RemovedItemBuilder<
Reorderable, E> ? -
An optional builder when an item was removed from the list.
finalinherited
- reorderDuration → Duration
-
The duration of the animation when an item is being translated
to a new position in the list, i.e. when the item is reordered.
final
- reverse → bool
-
Whether the scroll view scrolls in the reading direction.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- scrollDirection → Axis
-
The axis along which the scroll view scrolls.
final
- settleDuration → Duration
-
The duration of the animation when an item is released and settles
to its final destination in the list.
final
- shrinkWrap → bool
-
Whether the extent of the scroll view in the scrollDirection should be
determined by the contents being viewed.
final
- spawnIsolate → bool?
-
Whether to spawn a new isolate on which to calculate the diff on.
finalinherited
- updateDuration → Duration
-
The duration of the animation when an item changed in the list.
finalinherited
-
updateItemBuilder
→ UpdatedItemBuilder<
Reorderable, E> ? -
An optional builder when an item in the list was changed but not its position.
