Simpler and shorter listener code

[bilogic]

For the example here https://orchid.software/en/docs/listener/
I propose we write it in the following way, will it create any issues? e.g. adding more rows dynamically to a table etc?

public function layout(): array
{
    return [
        Layout::rows([
            Input::make('a')
                ->title('First argument')
                ->type('number'),

            Input::make('b')
                ->title('Second argument')
                ->type('number'),
        ]),
        Listener::make('AmountListener')    // do we actually need make()?
            ->target(['a', 'b'])            // or can we just start with target()?
            ->method('asyncSum')
            ->layout(function () {
                return Layout::rows([
                    Input::make('sum')
                        ->readonly()
                        ->canSee($this->query->has('sum')),
                ]);
            }),
    ];
}

@tabuna can AmountListener be on the same row as a and b?
The example given puts them on different rows. Thank you.

So it would be much better to treat the Listener as a dynamic field, not a separate layout.
