错误：根据闭包上下文的要求，返回类型“NetworkImage”不是“Widget”

Question

import 'package:carousel_pro/carousel_pro.dart';
import '../models/post_model.dart';

Carousel(
        animationDuration: null,
          images: [
               ListView.builder(
                      itemCount: posts[index].MediaImage.length,
                          physics: ScrollPhysics(),
                             itemBuilder: (context, index) {
                                  return NetworkImage(posts[index].MediaImage[index].image);
                                }, ) ],) ,

I am trying to show multiple images from Network. Does anybody know why i am getting this error?

Answer 1

Return the following in your itemBuilder

return Image.network(posts[index].MediaImage[index].image);

Answer 2

You cant use a ListView.builder inside of carousel, why would you even use that??

Carousel expect NetworkImage only as a string of url and placing any other widget inside of that will land you to this error.

import 'package:carousel_pro/carousel_pro.dart';
import '../models/post_model.dart';

Carousel(
        animationDuration: null,
          images: [NetworkImage(posts[i].MediaImage[i].image.toString(),],) ,

This is the correct way, .toString(), is often required as NetworkImage expects a String.

If you have multiple images use:

for(int i =0;i<="please specify your length here", i++);

I have added i in place of index.

Carousel never takes anyother Widget than AssetImage or NetworkImage directly.

It's a bit confusing from the way that Flutter names things, but NetworkImage is an ImageProvider , not a Widget (which actually shows the image). The widget you want is Image , which can be constructed from an ImageProvider , or can be constructed from an URL directly via its Image.network constructor .
