Install plugin from another plugin

Question

I'm trying to use Redactor as a dependency for a plugin I'm writing. I need it to be installed before I run my Install.php migration, because in the migration I'm creating a Redactor field.

Following this question I tried to listen to the AFTER_LOAD_PLUGINS Event:

use craft\services\Plugins;
use yii\base\Event;
use craft\redactor\Plugin as Redactor;

class Plugin extends \craft\base\Plugin
{
    public function init()
    {
        parent::init();

        Event::on(Plugins::class, Plugins::EVENT_AFTER_LOAD_PLUGINS, function () {
            Redactor::getInstance()->install();
        });
    }
}

However Redactor::getInstance() still returns null.

Answer 1

Redactor::getInstance(), will return the instance of the plugin, only if it is already installed.

Have you tried using Craft::$app->getPlugins()->installPlugin('redactor');?
