ExpansionPanelList class - material library

Constructors

ExpansionPanelList({Key key, List<ExpansionPanel> children: const [], ExpansionPanelCallback expansionCallback, Duration animationDuration: kThemeAnimationDuration }): Creates an expansion panel list widget. The expansionCallback is triggered when an expansion panel expand/collapse button is pushed. [...]
const
ExpansionPanelList.radio({Key key, List<ExpansionPanelRadio> children: const [], ExpansionPanelCallback expansionCallback, Duration animationDuration: kThemeAnimationDuration, Object initialOpenPanelValue }): Creates a radio expansion panel list widget. [...]
const

animationDuration → Duration: The duration of the expansion animation.
final
children → List<ExpansionPanel>: The children of the expansion panel list. They are laid out in a similar fashion to ListBody.
final
expansionCallback → ExpansionPanelCallback: The callback that gets called whenever one of the expand/collapse buttons is pressed. The arguments passed to the callback are the index of the to-be-expanded panel in the list and whether the panel is currently expanded or not. [...]
final
initialOpenPanelValue → Object: The value of the panel that initially begins open. (This value is only used when initializing with the ExpansionPanelList.radio constructor.)
final
hashCode → int: The hash code for this object. [...]
read-only, inherited
key → Key: Controls how one widget replaces another widget in the tree. [...]
final, inherited
runtimeType → Type: A representation of the runtime type of the object.
read-only, inherited

createState() → State<StatefulWidget>: Creates the mutable state for this widget at a given location in the tree. [...]
override
createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree. [...]
inherited
debugDescribeChildren() → List<DiagnosticsNode>: Returns a list of DiagnosticsNode objects describing this node's children. [...]
@protected, 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 toStringDeep. [...]
inherited
toString({DiagnosticLevel minLevel: DiagnosticLevel.debug }) → String: Returns 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.
