How to run function after plugin installed? How can I run a function when my plugin is installed? I tried SafeUp in migrations but it doesn't work.
There's an event you can listen to:

use craft\events\PluginEvent;
use craft\services\Plugins;

        // Handler: EVENT_AFTER_INSTALL_PLUGIN
        Event::on(
            Plugins::class,
            Plugins::EVENT_AFTER_INSTALL_PLUGIN,
            function (PluginEvent $event) {
                if ($event-&gt;plugin === $this) {
                    // Do stuff here, we were just installed
                }
            }
        );


If you generate your plugin scaffolding via pluginfactory.io it will generate the above event for you in your base plugin.
