Static Methods

persistent({Key? key, required Widget child, double initialChildSize = 0.5, double minChildSize = 0.25, double maxChildSize = 1.0, bool snap = true, List<double>? snapSizes, bool showDragHandle = true, double? borderRadius, Color? backgroundColor, EdgeInsetsGeometry? padding, DraggableScrollableController? controller, bool visible = true, Duration enterDuration = const Duration(milliseconds: 300), ValueChanged<double>? onSizeChanged, double? hideHandleThreshold, double? dismissThreshold, VoidCallback? onDismissed}) → Widget
创建一个【常驻、非模态】底部面板（高德地图首页那种效果）
scaffold({Key? key, required Widget background, required Widget sheetChild, Widget overlayBuilder(BuildContext context, double extent)?, double initialChildSize = 0.5, double minChildSize = 0.25, double maxChildSize = 1.0, bool snap = true, List<double>? snapSizes, bool showDragHandle = true, double? borderRadius, Color? backgroundColor, EdgeInsetsGeometry? padding, DraggableScrollableController? controller, bool visible = true, Duration enterDuration = const Duration(milliseconds: 300), double? hideHandleThreshold, double? dismissThreshold, VoidCallback? onDismissed}) → Widget
一站式【常驻面板布局壳】：背景 + 常驻面板 + 联动浮层，三层 Stack 自动摆好
show<T>(BuildContext context, Widget child, {double? height, bool fullScreen = false, bool draggableScrollable = false, double initialChildSize = 0.5, double minChildSize = 0.25, double maxChildSize = 1.0, bool snap = false, List<double>? snapSizes, bool enableDrag = true, bool isDismissible = true, bool showDragHandle = true, double? borderRadius, Color? backgroundColor, Color? barrierColor, EdgeInsetsGeometry? padding, VoidCallback? onDismiss}) → Future<T?>
