Background

Start by refactoring the background. Open lib/components/brackground.dart and create a class that extends SpriteComponent.

import 'package:flame/components.dart';

class Background extends SpriteComponent {

}

          GameConstants.cameraWidth,
          GameConstants.cameraHeight,

      );

Spaceship

Spaceship‘s sprite is located in a different image you’ll need to load it first. In onLoad function, load the spritesheet to Flame like so:

await Flame.images.load('meteormania_spritesheet.png');

Meteorite

Adding a Meteorite is a bit trickier since it needs to be positioned randomly in the screen.
