Getting "No file or variants found for asset" found error on my asset - android-studio

Question

I am getting this attached error when I try and run my app. Any ideas?
(Below)
Launching lib\main.dart on SM J200Y in debug mode...
Running Gradle task 'assembleDebug'...
√ Built build\app\outputs\apk\debug\app-debug.apk.
Error detected in pubspec.yaml:
No file or variants found for asset: assets/credentials.json.
I have checked the yaml file and the formatting seems to be fine. I am at a loss as want the issue is. (Also, below)
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/credentials.json

Answer 1

In my case, the problem was that I was missing slash /.
At first, I have added my icons path as below.
assets:
- assets/icons
I solve the issue by adding as slash / to the end of the path as below:
assets:
- assets/icons/

Answer 2

Check identation of assets. Generally it should have 3 spaces from start of new line.
assets:
- assets/credentials.json // <-- count three spaces from start

Answer 3

I was facing the same problem, and I had two mistakes:
I created the "images" folder inside the "lib" folder, and it should be outside the lib folder, it should be in the app root folder.
It should be three spaces from the starter line as #Darshan said
-assets/credentials.json // <-- count three spaces from start
It should appear a grey line, like this

Answer 4

there are 2 possibility
Folder/file missing in your project directory
Missing "/" in the end of folder/file name in pubspec.yaml file

Answer 5

try copying the file manually not using VS-Code or Android studio. don't use drag/drop.

Answer 6

You need mention as
assets:
- assets/icons/
in pubspec.yaml

Answer 7

I had this same problem, I was able to fix it by using only the name of directory created in the projects root folder, instead of also including the file i was trying to point to.
assets:
- images/
is what worked for me instantly, just point to the whole dir and specify the file name in ImageAssets object.

Answer 8

Sometimes you need to enter filename as such:
flutter: assets:
- lib/assets/logo.png

Answer 9

I was facing the same problem, and I had two mistakes:
When I add lib in assets then I solve my problem.
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:
- lib/images/background.jpg
