Answer 1

You should respect the indentation, it won't work if you add or remove even one space, this is how you should do it:

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

The best way is to copy/past it from the official documentation .

Answer 2

1. I have created assets/images folder in root of the project and placed icon.png and gplus.png images files in to it.

2. Then I have defined image resources in pubspec.yaml file like below image

3. Then used image in project like below

Answer 3

If the above solutions did not work

Try to restart your IDE(Andriod studio/VSCode), its work for me
