LoadingIndicator class

A Material Design loading indicator, which shows the progress for a short wait time.

A widget that displays an animated, morphing shape to indicate ongoing activity. There are two variants of loading indicators:

Default (Non-contained): the active loading indicator appears without a background container.
Contained. The active loading indicator is displayed over a container surface.

LoadingIndicator({List<RoundedPolygon>? indicatorPolygons, Color? activeIndicatorColor, Color? containerColor, String? semanticsLabel, Key? key}): Creates a default (non-contained) version of LoadingIndicator.
LoadingIndicator.contained({List<RoundedPolygon>? indicatorPolygons, Color? activeIndicatorColor, Color? containerColor, String? semanticsLabel, Key? key}): Creates a contained version of LoadingIndicator.

activeIndicatorColor → Color?: Color of the active indicator shape.
final
containerColor → Color?: Color of the background container.
final
hashCode → int: The hash code for this object.
no setterinherited
indicatorPolygons → List<RoundedPolygon>: A list of RoundedPolygons for the sequence of shapes this loading indicator will morph between as it progresses.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
semanticsLabel → String?: The semantic label for this loading indicator. This value is read aloud to describe the indicator’s purpose. It corresponds to SemanticsProperties.label.
final

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<LoadingIndicator>: 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 nonexistent 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, int wrapWidth = 65}) → 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.

determinateIndicatorPolygons → UnmodifiableListView<RoundedPolygon>: The sequence of RoundedPolygons that the determinate LoadingIndicator will morph between when animating.
final
indeterminateIndicatorPolygons → UnmodifiableListView<RoundedPolygon>: The sequence of RoundedPolygons that the indeterminate LoadingIndicator will morph between when animating.
