Javascript Phaser3 Assets Not Loading In Create Function

I’m trying to do what seems to be basic image loading into my phaser3 game outside Phaser’s preload function, but nothing is working.

I tried:

• Lazy loading function in my utils.js:

dynImgLoader(textureKey,x,y,asset)
{
    let loader = new Phaser.Loader.LoaderPlugin(this.scene);
    loader.image(textureKey,asset);
    loader.once(Phaser.Loader.Events.COMPLETE, ()=>
    {
        console.log('sprite ready for usage');
    })
    loader.start();
}

When called it still gives me the default phaser asset image (not loaded)

• I tried what this tutorial told me in index.js in create function:

    this.load.image('arc_red', arc_red);
    this.load.onLoadComplete.add(this);
    this.load.start();

Still does not work.

Question:

How do I “dynamically” load assets for a multiplayer web socket game without using the preload function? And why is it that I am doing wrong?

I’m new to phaser and I desperately need to learn, thanks.
