我用PageView替换了滚动小部件，它工作正常

PageView(
    onPageChanged: (int page) {},
    controller: pageController,
    children: List.generate(5, (index) {
      return Container(
        constraints: BoxConstraints(
          maxHeight: constraints.maxHeight / 1.5,
          minWidth: constraints.maxWidth,
          maxWidth: constraints.maxWidth,
        ),
        padding: const EdgeInsets.symmetric(
          vertical: 10,
        ),
        child: ProfilePicture(
          pathImage: "assets/debug/girl.jpg",
          width: constraints.maxWidth,
          height: constraints.maxHeight,
          borderRadius: BorderRadius.circular(0),
          onPressed: null,
        ),
      );
    }).toList().cast<Widget>(),
  );
