How to solve the error In CachedNetworkImage?












0















I want to load an image to cache. So I used CachedNetworkImage for that. When a user logged in through gmail account I get the image url and show the image. But I need to keep it in cache.
Here is my code:



new Center(
child: new Column(
children: <Widget>[
new CircleAvatar(
new CachedNetworkImage(
placeholder: CircularProgressIndicator(),
imageUrl: widget.currentUser?.profilUrl,
),
),
],
),
)


I used CachedNetworkImageProvider also but same error is coming for both. The error is



type'CachedNetworkImage'is not  a  subtype  of  type  'ImageProvider<dynamic>'

          The widget CircleAvatar receives an ImageProvider.



          The cached_network_image package offers you two classes to use:





          1. CachedNetworkImage a Widget you can use to display a cached network image.


          2. CachedNetworkImageProvider an ImageProvider providing the cached image.


          Therefore you gotta use CachedNetworkImageProvider(2.), if you want to pass it to the CircleAvatar.



          Here is a complete example, that you can copy & paste for trying out:



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

          void main() => runApp(MyApp());

          class MyApp extends StatelessWidget {
          @override
          Widget build(BuildContext context) {
          return MaterialApp(
          theme: ThemeData(),
          home: Scaffold(
          body: Center(
          child: CircleAvatar(
          backgroundImage: CachedNetworkImageProvider(
          'https://upload.wikimedia.org/wikipedia/commons/thumb/7/71/Bill_Gates_Buys_Skype_%285707954468%29.jpg/2560px-Bill_Gates_Buys_Skype_%285707954468%29.jpg'
          ),
          ),
          ),
          )
          );
          }
          }

            Just like @Niklas say.




            The widget CircleAvatar receives an ImageProvider.




            this is how to use:



             new Center(
            child: new Column(
            children: <Widget>[
            new CircleAvatar(
            backgroundImage: new CachedNetworkImageProvider(
            widget.currentUser?.profilUrl,
            )
            ),
            ],

                Just like @Niklas say.




                The widget CircleAvatar receives an ImageProvider.




                this is how to use:



                 new Center(
                child: new Column(
                children: <Widget>[
                new CircleAvatar(
                backgroundImage: new CachedNetworkImageProvider(
                widget.currentUser?.profilUrl,
                )
                ),
                ],
                ),
                )
