i mentioned images files in wrong way. i put space between '-' and image name instead of tab.

assets:

- assets/images/logo.png

Don't put spaces between the character instead of tab in pubspec.yaml file

There may be two issues:

1.) Either you pubspec.yaml file is not having proper indention. Attaching snippet for reference.

flutter:  
  uses-material-design: true   
  assets:   
    - assets/

- assets/ will consider all the images in the directory.

2.) If you are using .jpg image then please change it to .jpeg wherever you are calling it.

Attaching the snippet for you reference

class _UserLoginState extends State<UserLogin> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Stack(
        children: <Widget>[
          Image(image: AssetImage("assets/christmas.jpeg"),
          fit: BoxFit.cover,
        ],
      )
    );
  }

  • My issue was incorrect indentation. As a newbie to Flutter I just hit backspace to remove #, which makes keyword 'assets' sent to beginning of the line. – Hareen Laks May 23 '19 at 05:44

Make sure the folder you are referring in Image.asset contains the file.

For example:

Image.asset(
"./assets/images/loading.gif",
height: 125.0,
width: 125.0,
)

The folder should be:

C:\your_app_folder\assets\images

pubspec.yaml:

  assets:
    - assets/
    - assets/images/

Run flutter clean to clean the intermediate files and refresh.

Hot Reload was the issue in my case. I simply restarted the Android studio and re-run the app, it all worked!.

I assume you copied your files inside assets/images/ folder right? Also you need to reference your images into the pubspec.yaml file.

  flutter:

  ...

    assets:
      - assets/images/logo.png

Make sure your image folder is in project folder.

There are several opportunities to make the mistake, higher chance that it's in the pubspec.yaml declaration.

  • Most of the time it's better to specify the directory of your assets. This way you'll edit pubspec.yaml less frequently.
  • The asset directory/item is not declared properly (e.g. wrong indent)
  • If your IDE is Android Studio and you edited the pubspec, hitting the Run button won't cut it. Execute flutter run in the Terminal to run the app.
  • If you can't type in the Terminal, flutter may already be running. Press ctrl + c to terminate the process then run. No need to restart your IDE.

Refer https://api.flutter.dev/flutter/painting/AssetImage-class.html

Add assets images in pubspec.yaml file and in the asset mention the path from images and it works fine.

 new AssetImage("images/logo.png")

For example

CircleAvatar(
  radius: 80,
  backgroundImage: AssetImage('images/logo.png'),
 ),

  • I appreciate your kindness towards action on other correct answers. we have given solution to the problem after checking in our environment. Please go through the link https://api.flutter.dev/flutter/painting/AssetImage-class.html and confirm using above code, user can load an image using the above code (AssetImage) – Jayakumar Thangavel Mar 22 '20 at 19:56

I just replaced

Image.asset("assets\images\_Lightweight.jpeg"),

To

Image.asset("assets/images/_Lightweight.jpeg"),

my problem was indentation of assets section. I wrote it at the beginning of the line, whereas it should be indented with a Tab after flutter: section.

I faced the same issue after adding a new image to the asset folder. I was doing "Hot Reload", I destroyed the app from the background, re-run the app and the problem got resolved.

Your pubspec.yaml is not intended properly

flutter:
  uses-material-design: true

  assets:
    - images/

Check if it's intended this way.

These changings will definately work.

AssetImage('mypicture.jpg')

Above is my code, I have not used "assets" folder name with my image file name and it works perfect.

and these are my assets in 'pubspec.yaml' file.

assets:
    - assets/cat.png
    - assets/mypicture.jpg```

  1. Flutter doesn't support jpg files.
  2. Try the complete path of the file with '/'(forward slash).

I was facing the same issue and did everything mentioned but the problem was I was using a route that was initializing another file first instead of my asset. you can also check this if the problem persists
