<?php

namespace SleepingOwl\Admin\Traits;

use Closure;

trait VisibleCondition
{
    /**
     * @var Closure|null
     */
    protected $visibleCondition;

    /**
     * @return bool
     */
    public function isVisible()
    {
        if (is_callable($this->visibleCondition)) {
            return (bool) call_user_func($this->visibleCondition, $this->getModel());

It seems like getModel() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        }

        return true;
    }

    /**
     * @param Closure $condition
     *
     * @return $this
     */
    public function setVisibilityCondition(Closure $condition)
    {
        $this->visibleCondition = $condition;

        return $this;
    }
}
