kshowDialogSize function

Future<void> kshowDialogSize(BuildContext context, { required Widget child, int width = 0, int? height, 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-设置固定宽度

context child 内容 width 宽度 height 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

           kshowDialogSize(
              context,
              width: 100,
              height: 100,
              insetPadding: EdgeInsets.only(left: 0, right: 0),
              backgroundColor: Colors.red,
              contentPadding: EdgeInsets.all(0),
              radius: 16,
              child: Column()
            );

Implementation

Future<void> kshowDialogSize(
  BuildContext context, {
  required Widget child,
  int width = 0,
  int? height,
  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,
}) async {
  return await showDialog<void>(
    context: context,
    barrierDismissible: barrierDismissible,
    barrierColor: barrierColor,
    //在iOS上，顶部和下部当有SafeArea时，会留有一片区域空白，原因是showDialog有个属性useSafeArea默认为 true，改为fasle即可
    useSafeArea: false,
    builder: (BuildContext context) {
      return UnconstrainedBox(
        constrainedAxis: Axis.vertical,
        child: SizedBox(
          width: width.w,
