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. 1 of these events are declared but no code emits them yet; they are marked not emitted.

Setup

Import PluginManagerEvent 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\PluginManagerEvent;

class MyPlugin implements AppPlugin
{
    public static function processEvents(PluginEvents $event): void
    {
        $event->on(PluginManagerEvent::onPluginFileCreated(), function ($identifier, $fileType, $fileData, $createdBy): void {
            App::getInstance(true)->getLogger()->info('[myplugin] featherpanel:admin:plugin_manager:file:created ' . json_encode(['identifier' => $identifier, 'file_type' => $fileType, 'file_data' => $fileData]));
        });
    }

    public static function pluginInstall(): void
    {
    }

    public static function pluginUninstall(): void
    {
    }
}

`PluginManagerEvent::onPluginManagerError()`

$event->on(PluginManagerEvent::onPluginManagerError(), function (...$args): void {

});

No code emits this event yet, so the arguments are unknown. The listener accepts any.
