WheelOverlayEntryContentState class
- Inheritance

- Object
- State<
WheelOverlayEntryContent> - WheelOverlayEntryContentState
Constructors
Properties
-
angleOffsetNotifier
↔ ValueNotifier<
double> -
angle offset value notifier, initialized with 0 rotation
when user pan on the wheel, rotate the wheel with angle
ValueNotifier is used to reduce the amount of repaint
getter/setter pair
-
animation
↔ Animation<
double> -
rotation animation, other animations are handled individually by each slice
rotation is cancelled for now
also see FanSliceWidget
generated by initState ->
_initAnimation
getter/setter pair - center ↔ Offset
-
Center of the wheel, generated by initState ->
_initCalculateCenter
getter/setter pair - context → BuildContext
-
The location in the tree where this widget builds.
no setterinherited
-
fanSliceList
↔ List<
FanSlice> -
List of fan pieces generated by initState ->
_initFanSliceList
with respect to colorsgetter/setter pair - hashCode → int
-
The hash code for this object.
no setterinherited
- mounted → bool
-
Whether this State object is currently in a tree.
no setterinherited
- outerRadius ↔ double
-
outerRadius is initialized by initState ->
_initCalculateOuterRadius
_initCalculateOuterRadius
needs to be called before_initCalculateCenter
latefinal - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- widget → WheelOverlayEntryContent
-
The current configuration.
no setterinherited
Methods
-
activate(
) → void -
Called when this object is reinserted into the tree after having been
removed via deactivate.
inherited
-
build(
BuildContext context) → Widget -
Describes the part of the user interface represented by this widget.
override
-
buildChild(
BuildContext context) → Widget -
callback(
FanPiece fanPiece) → void - on FanPieceWidget clicked, this function is invoked
-
deactivate(
) → void -
Called when this object is removed from the tree.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
didChangeDependencies(
) → void -
Called when a dependency of this State object changes.
inherited
-
didUpdateWidget(
covariant WheelOverlayEntryContent oldWidget) → void -
Called whenever the widget configuration changes.
inherited
-
dispose(
) → void -
Called when this object is removed from the tree permanently.
inherited
-
increaseAngleOffset(
double move) → void -
rotate the wheel, increment the angle by
move
-
initState(
) → void -
Initialize overlay entry content state

noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reassemble(
) → void -
Called whenever the application is reassembled during debugging, for
example during hot reload.
inherited
-
setState(
VoidCallback fn) → void -
Notify the framework that the internal state of this object has changed.
inherited
-
toDiagnosticsNode(
{String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode -
Returns a debug representation of the object that is used by debugging
tools and by DiagnosticsNode.toStringDeep.
inherited
-
toString(
{DiagnosticLevel minLevel = DiagnosticLevel.info}) → String -
A string representation of this object.
inherited
-
toStringShort(
) → String -
