Answer 1

you have to mentioned images in pubspect.yaml for used in project, like below.

flutter:
  assets:
  - assets/1.jpg

then you can use image like this,

 Image.asset('images/1.jpg')

Note:- make sure your image in folder named "images"

Answer 2

Create folder in main directory of project called assets, and inside create folder called images. To images folder add the image called 1.jpg. In your pubspec.yaml :

# The following section is specific to Flutter.
flutter:
  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/1.jpg

or to add whole directory of images:

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/

In your code:

 Image.asset('assets/images/1.jpg')

Answer 4

You need to add you image to pubspec.yaml:

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - images

I created a GitHub repo for this, please flow the same files structure, should work!

Answer 5

this worked for me Just uninstall then reinstall the app to clear empty or damaged file from app path in device.
