Part of the plugin events reference. Listeners get the payload values as positional arguments in the order shown, cannot cancel the action, and must catch their own exceptions. 4 of these events are declared but no code emits them yet; they are marked not emitted.

Setup

Import AllocationsEvent in your entry class and register listeners in processEvents():

<?php

namespace App\Addons\myplugin;

use App\App;
use App\Plugins\AppPlugin;
use App\Plugins\PluginEvents;
use App\Plugins\Events\Events\AllocationsEvent;

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(AllocationsEvent::onAllocationCreated(), function ($allocations, $createdCount, $createdBy): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:admin:allocations:allocation:created ' . json_encode(['allocations' => $allocations, 'created_count' => $createdCount]));
        });
    }

    public static function pluginInstall(): void
    {
    }

    public static function pluginUninstall(): void
    {
    }
}
