TopSheet constructor

const TopSheet({ required VoidCallback onClosing, required WidgetBuilder builder, Key? key, AnimationController? animationController, bool enableDrag = true, bool? showDragHandle, Color? dragHandleColor, Size? dragHandleSize, BottomSheetDragStartHandler? onDragStart, BottomSheetDragEndHandler? onDragEnd, Color? backgroundColor, Color? shadowColor, double? elevation, ShapeBorder? shape, Clip? clipBehavior, BoxConstraints? constraints, EdgeInsetsGeometry? padding, })

创建顶部工作表。

通常，顶部工作表由 showModalTopSheet 隐式创建。

Implementation

const TopSheet({
  required this.onClosing,
  required this.builder,
  super.key,
  this.animationController,
  this.enableDrag = true,
  this.showDragHandle,
  this.dragHandleColor,
  this.dragHandleSize,
  this.onDragStart,
  this.onDragEnd,
  this.backgroundColor,
  this.shadowColor,
  this.elevation,
  this.shape,
  this.clipBehavior,
  this.constraints,
  this.padding,
}) : assert(elevation == null || elevation >= 0.0);
