'How to solve exception caught by widgets library?

I want to use cached network image to display images in my flutter app, however it shows this:

═══════ Exception caught by widgets library ═══════════════════════════════════
Invalid argument (onError): Error handler must accept one Object or one Object and a StackTrace as arguments.: Closure: () => Null
The relevant error-causing widget was
CachedNetworkImage
lib/widgets/custom_image.dart:5
════════════════════════════════════════════════════════════════════════════════

custom_image.dart -

import 'package:flutter/material.dart';

Widget cachedNetworkImage(String mediaUrl) {
  return CachedNetworkImage(
    imageUrl: mediaUrl,
    fit: BoxFit.cover,
    placeholder: (context, url) => Padding(
      child: CircularProgressIndicator(),
      padding: EdgeInsets.all(20.0),
    ),
    errorWidget: (context, url, error) => Icon(Icons.error),
  );
}

Please help.

Wrap your CachedNetworkImage with a Container.

return Container(
width:...,
height:...,

child: CachedNetworkImage(..)));

After doing some research and trial and error.

I think the issue is in the package. The error you are getting was a bug in the old version of the HTTP package and I think your cached_network_image is outdated.

 Try flutter pub upgrade, resolve any
 dependency conflicts, do flutter clean, and flutter pub get.

Also, make sure your flutter SDK is updated as well.
