AppBarConnection class

Introduction

Synchronize appbars with Scrollable to configure dynamic appbar behavior by nested scroll for your cool and sexy, wonderful application.

See Also, And all of this can be implemented as a single Scrollable.

AppBarConnection(
  appBars: [ ...AppBar, ...AppBar.builder ],
  child: ... // the widget you want.
);

AppBarConnection({Key? key, required List<AppBar> appBars, required Widget child, AppbarPropagation propagation = AppbarPropagation.next, NestedScrollConnectionPropagation nestedPropagation = NestedScrollConnectionPropagation.directional, AppBarController? controller, NestedScrollController? scrollController, bool? fixedScrollableHeight}): const

appBars → List<AppBar>: final
child → Widget: final
controller → AppBarController?: The controller that defines states(AppBarPosition) and other features of the appbar.
final
fixedScrollableHeight → bool?: When true, the scrollable widget's height is always calculated as if the AppBar is fully collapsed, regardless of whether the AppBar is expanded or collapsed.
final
hashCode → int: The hash code for this object.
no setterinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
nestedPropagation → NestedScrollConnectionPropagation: Defines the propagation behavior for nested scroll connections. Determines how scroll events from child scrollables affect this AppBar.
final
propagation → AppbarPropagation: Defines how scroll offsets are propagated across nested AppBars.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scrollController → NestedScrollController?: The controller that defines scroll controller of PrimaryScrollController.
final

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<AppBarConnection>: 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.
inherited

defaultFixedScrollableHeight ↔ bool: A static default value for fixedScrollableHeight, used when no explicit value is provided.
getter/setter pair

of(BuildContext context) → AppBarConnectionState?: Finds the ancestor AppBarConnectionState from the closest instance of this class that encloses the given context.
