Properties

autoResizingAnimation → bool
if true, the drawer will be auto resized with animation when the height is changed. (when height is null only) it's cause overflow. so if you want to use this, autoResizingAnimation=kReleaseMode is recommended. default is false.
final
backgroundColor → Color
background color of the drawer. default is white.
final
builder → Widget Function(DrawerState state, void setState(void ()), BuildContext context)
builder of the drawer. DrawerState is the current state of the drawer. setState is the setState function of the drawer. it can be used to rebuild the drawer. (and, when height=null, height will be remeasured) context is the context of the drawer.
final
cornerRadius → double
corner radius of the drawer. default is 8.
final
expandedHeight → double
expanded height of the drawer.
final
handleColor → Color
color of the handle. default is #E0E0E0
final
handleSectionHeight → double
height of the handle section. default is 28.
final
handleSize → Size
size of the handle. default is 40x4.
final
hashCode → int
The hash code for this object.
no setterinherited
height → double?
closed height of the drawer. if null, the height is set to the height of the child widget.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onHeightChanged → (void Function(double height)?)
callback when the height is changed.
final
onReady → (void Function(DrawerMoveController controller)?)
callback when the drawer is ready. you can use DrawerMoveController to control the drawer.
final
onStateChanged → (void Function(DrawerState state)?)
callback when the state is changed.
final
resizeAnimationDuration → Duration
duration of the auto resizing animation. default is 300ms.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
shadows → List<BoxShadow>?
shadows of the drawer. default is defaultShadow.
