我是 vue.js 的新手，刚从 react.js 过来。我在 vue 加载器中面临的问题一开始并没有发生。但是从第二次启动服务器时应用程序崩溃。

 npm run serve

> vue-cli-service serve

我已将资源文件添加到项目根目录中，其中包含图像、字体和声音。

在 pubspec.yml 文件中添加资产，如下所示：

flutter:\n\n  uses-material-design: true\n\n  assets:\n    - assets/images/\n

然后我尝试通过 Image.asset 添加图像，如下代码：

Scaffold(\n      appBar: AppBar(\n        leading: Align(\n          alignment: Alignment.centerRight,\n          child: Text(\n            "Uber",\n            style: TextStyle(\n              fontSize: 22.0,\n              fontWeight: FontWeight.w400\n            ),\n          )\n        ),\n      ),\n      body: Column(\n        children: [\n          Text(\n            "riyad", \n            style: TextStyle(color: Colors.black),\n          ),\n          Image.asset("car_android.png") <-- this like \n        ],\n      ),\n    );\n

但它显示了无法加载资产的异常：

\n

解析图像编解码器时抛出以下断言：\n无法加载资源：car_android.png”

\n

我的回溯异常：

我正在尝试使用从 fetchData 钩子中获取数据，但奇怪的是它产生了以下错误->

  Line 26:31:  React Hook "useReducer" is called in function "fetchData" which is neither a React function component or a custom React Hook function  react-hooks/rules-of-hooks
  Line 28:5:   React Hook "useEffect" is called in function "fetchData" which is neither a React function component or a custom React Hook function   react-hooks/rules-of-hooks

我的 fetchData.js 文件代码 ->

import { useReducer, useEffect } from "react"
import axios from 'axios'

const ACTION = {
    MAKE_REQUEST: 'make_request',
    GET_DATA: 'get_data',
    ERROR: 'error'
