Flutter,pubspec.yaml file is showing some errors

Question

I don't know what is happening but I m not able to insert image through Asset image using pubspec.yaml file.Pub get is not loading dependencies.

Kindly please help me out. I am running a flutter project.

Here is the code of pubspec.yaml file

name: mi_card_flutter
description: A new Flutter application.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.
version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter
flutter:
  uses-material-design: true
  assets:
    images/khushi.jpg

Error is :

Error detected in pubspec.yaml: Expected "assets" to be a list, but got images/ (String). Please correct the pubspec.yaml file at C:\Users\khush\AndroidStudioProjects\mi_card_flutter\pubspec.yaml Process finished with exit code 1

Your indentation of the images/kushi.jpg is wrong.

Try the code below: Works well:

name: mi_card_flutter
description: A new Flutter application.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.
version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

dev_dependencies:
  flutter_test:
    sdk: flutter
flutter:
  uses-material-design: true
  assets:
    -images/

I hope this helps.

Expected "assets" to be a list, but got -assests/images/ (String). what does this mean?

Please write in assets in pubspec.yaml file as shown below

dev_dependencies:
  flutter_test:
    sdk: flutter
flutter:
  uses-material-design: true
  assets:
    images/khushi.jpg

instead of this

dev_dependencies:
  flutter_test:
    sdk: flutter
flutter:
  uses-material-design: true
  assets:
    - images/khushi.jpg
