Tried to access an image "characters/amiy/idle.png" that does not exist in the cache. Make sure to load() an image before accessing it

What happened?

Maybe it's not a bug, but it's pretty weird, so my Player class requires a picture, and I'm sure I've loaded that before creating the player class but that's not working at all and warns
`he following assertion was thrown building FutureBuilder(dirty, state:
_FutureBuilderState#19a16):

and this is my code

    @override
    Color backgroundColor() {
        return const Color(0xff5fcde4);
    }

    @override
    FutureOr<void> onLoad() async {
        print('Amiy\'s Island is loading...');
        
        images.loadAllImages();

        world = Island();
        camera = CameraComponent.withFixedResolution(width: 600, height: 600);
        camera.viewfinder.anchor = Anchor.topLeft;
        add(Player(camera));
        print('test2');

        return super.onLoad();
    }
}```

my player class

class Player extends SpriteAnimationGroupComponent with KeyboardHandler, HasGameRef {
CameraComponent camera;
double velocity = 1.0;
late final SpriteAnimation idleAnimation;

Player(this.camera);

@override
bool onKeyEvent(KeyEvent event, Set<LogicalKeyboardKey> keysPressed) {
    if(keysPressed.contains(LogicalKeyboardKey.arrowLeft)) {
        camera.moveBy(Vector2(0-velocity, 0));
    }
    if(keysPressed.contains(LogicalKeyboardKey.arrowRight)) {
        camera.moveBy(Vector2(velocity, 0));
    }
    if(keysPressed.contains(LogicalKeyboardKey.arrowUp)) {
        camera.moveBy(Vector2(0, 0-velocity));
    }
    if(keysPressed.contains(LogicalKeyboardKey.arrowDown)) {
        camera.moveBy(Vector2(0, velocity));
    }

    return true;
}

@override
FutureOr<void> onLoad() {
    print('test1');
    idleAnimation = SpriteAnimation.fromFrameData(
        gameRef.images.fromCache('characters/amiy/idle.png'), 
        SpriteAnimationData.sequenced(
            amount: 4, 
            stepTime: 0.5, 
            textureSize: Vector2(32, 32)
        )
    );

    return super.onLoad();
}

}```

help is appreciated

@huanmoon have you added assets/images/characters/amiy/ to the assets section in your pubspec?

[ufrshubham]

Also, you'll have to await for loadAllImages() to complete loading all the images before proceeding with rest of the game setup.

god I'm literally a stupid and I didn't add /images/ before my file name =(
