controller → MarqueeController?: 控制器
final
direction → MarqueeDirection: 滚动方向
final
hashCode → int: The hash code for this object.
no setterinherited
infinite → bool: 是否无限循环
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
minScrollDistance → double: 最小滚动距离（只有当内容超出容器时才滚动）
final
onComplete → VoidCallback?: 滚动完成回调
final
pauseDuration → int: 滚动间隔（毫秒）
final
pauseOnHover → bool: 是否在鼠标悬停时暂停
final
runtimeType → Type: A representation of the runtime type of the object.

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.
