即使 HitTestBehaviour 设置为半透明，手势检测器也无法与堆栈一起工作

Question

我在 Flutter 上使用 CarouselView，我希望能够单击属于轮播成员的每个 ClipRRect 以转到新页面。轮播由包含堆栈的 ClipRRect 组成。

最初，我将堆栈包裹在手势检测器中并将 HitTestBehaviour 设置为半透明，但这不起作用。然后我将整个 ClipRRect 包裹在手势检测器中，但这也不起作用。 对于上下文，这是我的代码：

import 'package:flutter/material.dart';

class MyPracticesCarousel extends StatelessWidget {
  const MyPracticesCarousel({super.key});

  

  @override
  Widget build(BuildContext context) {
    return CarouselView(
      itemExtent: 320,
      shrinkExtent: 320,
      itemSnapping: true,
      padding: const EdgeInsets.all(8),
      children: List<Widget>.generate(10, (int index) {
        return MyPracticeCard();
      }),
    );
  }
}



class MyPracticeCard extends StatelessWidget {
  const MyPracticeCard({
    super.key,
  });

  void viewPractice(BuildContext context)
  {
    print("Card pressed");
  }

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () => viewPractice(context),
      behavior: HitTestBehavior.translucent,
      child: ClipRRect(
        borderRadius: BorderRadius.circular(20),
        child: Stack(
          children: [
            Container(
              decoration: const BoxDecoration(
                image: DecorationImage(
                  image: AssetImage("assets/GP_front_image.jpg"),
                  fit: BoxFit.cover,
                  alignment: Alignment.topCenter,
                ),
              ),
            ),
            Container(
              decoration: const BoxDecoration(
                gradient: LinearGradient(
                  colors: [
                    Colors.black,
                    Colors.transparent,
                  ],
                  begin: Alignment.bottomCenter,
                  end: Alignment.center,
                  stops: [0.0, 1],
                ),
              ),
            ),
            const Positioned(
              bottom: 15,
              left: 15,
              right: 15,
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [

CarouselView

具有内置

onTap

，它是一个 Inkwell，并且 GestureDetector 点击事件由此跳过。

你可以使用喜欢

return CarouselView(
  itemExtent: 325,
  itemSnapping: true,
  onTap: (int index) {
    //
  },
