Custom form field - Check if state has a value?

I'm creating a custom form field which extends the Radio field. How can i check if state has a value in the view? The idea is to dynamically hide something if state has a value.

I think $getState() should work

Is there a method to set state also?

Setting state from the view is a bit strange, but I think $state(...) should do it

quick action to clear the state. Ill link it to a method in livewire component via wire:click @Patrick Boivin 
    public function clearState(): void {
        $this->state(null);
    }

    <button  wire:click="clearState()">
        Clear
    </button>
    public function clearState(): void {
        $this->state(null);
    }

    <button  wire:click="clearState()">
        Clear
    </button>
Unable to call component method. Public method [clearState] not found on component

Any idea why this does't work? Not sure why the above wasn't working so just ended up using $set

There's not enough context, I need to see more code. But from what I see the button is probably outside of the livewire component you're trying to call this method on.
