Expected "assets" to be a list, but got -assets/image/ (String)

Question

I am getting the following exception in my pubspec.yaml file :

Error detected in pubspec.yaml:
Expected "assets" to be a list, but got -assets/image/ (String).
Please correct the pubspec.yaml file at D:\Working_Project\FlutterProject\flutter_change_color\pubspec.yaml

Solution 1

I had the same error I figured out that you must add assets like following:

Flutter uses the 'pubspec.yaml' file, located at the root of your project, to identify assets required by an app. Here is an example:

flutter:
  assets:
    - assets/my_icon.png
    - assets/background.png

To include all assets under a directory, specify the directory name with the / character at the end:

  assets:
    - directory/
    - directory/subdirectory/

Now lets come to your Error

Expected "assets" to be a list, but got -assets/image/ (String).

This Error has occurred as you did not add space between "- and assets". If you just add space It should solve your problem.

Solution 2

Using the correct format in pubspec.yaml file is very important. use:

assets:
   - assets/images

(space between the strings - and assets/images is necessary)

Solution 3

You need to put a space between dash(-) and the "assets"

- assets/image/

Solution 4

flutter returns this error because the input is not correctly formatted.

the correct format is as follows

flutter:
 assets:
  -folder/file.png

Solution 5

uses-material-design: true

# To add assets to your application, add an assets section, like this: assets: - images/pic.jpeg - images/pic1.jpeg

aligned uses-material-design: true and assets: to the margin then flutter clean then flutter run

This solved my problem. The space does matter.

A bit of an overkill, is'nt it?
