Asset image in flutter

*Note:-
     Very important thing to note while using asset is that:
--> In "pubspec.yaml" file:-
	line with code "uses-material-design: true"
    and line with code "  assets:"
    should lie in same column 
    
--> example:-
  # the material Icons class.
  uses-material-design: true    //this line

  # To add assets to your application, add an assets section, like this:
  assets:                      // and this line (in same column)
     - assets/
--> Don't be oversmart and give your image name too in assets like this:-
  "  assets:
     - assets/onePiece"
     This will cause error....(Believe it)....
