Methods

build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
override
createElement() → StatelessElement
Creates a StatelessElement to manage this widget's location in the tree.
inherited
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.

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

Static Methods

clearPreferences(BuildContext context, Iterable<String> steps) → Future<void>
completeCurrentStep(BuildContext context) → Future<void>
This will force the completion of the current step and continue onto the next step after the completion animation of the current overlay.
currentFeatureIdOf(BuildContext context) → String?
This returns the feature id of the current feature discovery step, i.e. of the DescribedFeatureOverlay that is currently supposed to be shown, or null.
discoverFeatures(BuildContext context, Iterable<String> steps) → void
Steps are the featureIds of the overlays. Though they can be placed in any Iterable, it is recommended to pass them as a Set because this ensures that every step is only shown once.
dismissAll(BuildContext context) → void
A method to dismiss all steps.
hasPreviouslyCompleted(BuildContext context, String featureId) → Future<bool>
This will return true iff this featureId has been recorded as completed in the Shared Preferences.
