Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
animateSheet(double size) Future<void>
Animate sheet to a specific size
animateTo(double size, {required Duration duration, required Curve curve}) Future<void>
Animates the attached sheet from its current size to the given size, a fractional value of the parent container's height.
inherited
closeAssetsPicker() Future<void>
Close the assets picker
closePicker() Future<void>
Close the picker
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
hide() Future<void>
Hide the sheet
jumpTo(double size) → void
Jumps the attached sheet from its current size to the given size, a fractional value of the parent container's height.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
pixelsToSize(double pixels) double
Convert a sheet's pixel height to size (fractional value of parent container height).
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
reset() → void
Reset the attached sheet to its initial size (see: DraggableScrollableSheet.initialChildSize).
inherited
sizeToPixels(double size) double
Convert a sheet's size (fractional value of parent container height) to pixels.
inherited
toString() String

inherited
tryToHide() Future<void>
