Constructors
-
FResizableController({void onResizeUpdate(List<
FResizableRegionData> resized)?, void onResizeEnd(List<FResizableRegionData> resized)?, double hapticFeedbackVelocity}) -
Creates a FResizableController.
factory
-
FResizableController.cascade({void onResizeUpdate(List<
FResizableRegionData> resized)?, void onResizeEnd(UnmodifiableListView<FResizableRegionData> all)?, double hapticFeedbackVelocity}) -
Creates a FResizableController that cascades shrinking of a region below its minimum extent to its neighbours.

Properties
- disposed → bool
-
True if this notifier has been disposed.
no setterinherited
- hapticFeedbackVelocity → double
-
The minimum absolute per-frame delta, in pixels, required for haptic feedback to fire on a collision between
neighbouring regions.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.
no setterinherited
-
regions
→ List<
FResizableRegionData> -
The resizable regions. The regions are ordered from top to bottom, or left to right, depending on the resizable
axis.
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
dispose(
) → void -
Discards any resources used by the object.
inherited
-
end(
int left, int right) → void - Notifies the region at the indexes that they and their neighbours have been resized.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
resize(
int left, int right, double delta) → List< FResizableRegionData> -
Returns the regions resized by
delta. -
toString(
) → String -
A string representation of this object.
inherited
-
update(
int left, int right, double delta) → bool - Updates the regions at the given indexes in addition to their neighbours. Returns true if haptic feedback should be performed.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
