How to fix this error "missing ) after argument list"?

I’m trying to create a grid but it throws me an error:

    this.add.grid(width: 10,
            height: 10,
            cellWidth: 32,
            cellHeight: 32,
            x: 100,
            y: 100,
    	    fillColor:0xff1100,
	        outlineFillColor:0x000000);

Shouldn’t it be this.add.grid( {
} );
multiple parameters inside curly braces.

I’ve not used a grid, I’m just assuming based on other functions that have multiple parameters like a tween or audio.

I found another solution but thanks anyway
