Help with block field editors - large image grid picker?

This is only supported in beta (https://makecode.microbit.com/beta). Use imageLiteralColumns and imageLiteralRows.

For legacy reasons, the parameter should be a string; but it is really an Image runtime object.

    /**
     * TODO: describe your function here
     */
    //% block="foo"
    //% imageLiteral=1
    //% imageLiteralColumns=12
    //% imageLiteralRows=3
    export function foo(i: string): void {
        // this is not pretty but basically, i is an Image
        let im = <Image><any>i;
        im.showImage(0)
    }
