kshowDialogMinSize function

Future<void> kshowDialogMinSize(BuildContext context, { required Widget child, double minWidth = 0.0, double minHeight = 0.0, int radius = 0, Color? backgroundColor, Color? barrierColor, bool barrierDismissible = true, EdgeInsets insetPadding = const EdgeInsets.only(left: 0, right: 0), EdgeInsetsGeometry contentPadding = const EdgeInsets.all(0), AlignmentGeometry? contentAlignment = Alignment.topLeft, AlignmentGeometry? dialogAlignment = Alignment.center, })

自定义对话框-设置最小宽高

context child 内容 minWidth 最小宽度 minHeight 最小高度 radius 圆角 backgroundColor 背景颜色 barrierColor dialog空白区域颜色 barrierDismissible 点击空白区域是否隐藏 insetPadding 外边距 contentPadding 内边距 contentAlignment 内容对其方式 dialogAlignment 对话框显示位置

            kshowDialogMinSize(
              context,
              minWidth: 200,
              minHeight: 200,
              backgroundColor: Colors.red,
              contentPadding: EdgeInsets.all(16),
              radius: 16,
              child: Column(),
            );
