Flutter：当我尝试热重载来运行应用程序时，在使用轮播滑块时出现此错误“错误：无法解析包'carousel_slider”

Question

我一直使用列表视图来显示我的图像，一切正常，但是当我尝试切换到轮播滑块包时，在安装它的那一刻，我收到了这些错误

我尝试更改软件包版本，删除了构建文件夹，但似乎没有任何效果

我在主包内有一个名为 Koulch-UI 的子包，轮播幻灯片位于其中，这是 pubspec

name: koulch_ui

dev_dependencies:
  flutter_test:

这是代码

import 'package:carousel_slider/carousel_slider.dart';
import 'package:flutter/material.dart';

class CarouselSliderTemplate extends StatefulWidget {
  final height;
  final Clip? clipBehaviour;
  final images;
  const CarouselSliderTemplate(
      {super.key, this.images, this.height, this.clipBehaviour});

  @override
  State<CarouselSliderTemplate> createState() => _CarouselSliderTemplateState();
}

class _CarouselSliderTemplateState extends State<CarouselSliderTemplate> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: CarouselSlider(
          items: widget.images,
          options: CarouselOptions(
            height: widget.height,
            clipBehavior: widget.clipBehaviour!,
            enlargeCenterPage: true,
            autoPlay: true,
            aspectRatio: 16 / 9,
            autoPlayCurve: Curves.fastOutSlowIn,
            enableInfiniteScroll: true,
            autoPlayAnimationDuration: Duration(milliseconds: 800),
            viewportFraction: 0.8,
          )),
    );
  }
}

抱歉，我对编码比较陌生，所以，也许这是一个愚蠢的问题

Answer 1

抱歉，我尝试了两个修复程序，我不确定哪个有效，但现在它已经修复了 1-我尝试删除 Flutter 构建缓存。

2-然后我手动删除了 dart_tool 文件夹

然后我运行了 pub-get 和 flutter run，现在它可以工作了。
