Constructors

CupertinoActivityIndicator({Key? key, Color? color, bool animating = true, double radius = _kDefaultIndicatorRadius}): Creates an iOS-style activity indicator that spins clockwise.
const
CupertinoActivityIndicator.partiallyRevealed({Key? key, Color? color, double radius = _kDefaultIndicatorRadius, double progress = 1.0}): Creates a non-animated iOS-style activity indicator that displays a partial count of ticks based on the value of progress.
const

animating → bool: Whether the activity indicator is running its animation.
final
color → Color?: Color of the activity indicator.
final
hashCode → int: The hash code for this object.
read-onlyinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
progress → double: Determines the percentage of spinner ticks that will be shown. Typical usage would display all ticks, however, this allows for more fine-grained control such as during pull-to-refresh when the drag-down action shows one tick at a time as the user continues to drag down.
final
radius → double: Radius of the spinner widget.
final
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<CupertinoActivityIndicator>: Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void: Add additional properties associated with the node.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
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
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String: Returns a one-line detailed description of the object.
inherited
toStringShort() → String: A short, textual description of this widget.
