Solved Command not working

So i tried but this doesnt work :/ not sure what i did wrong the command is registered but when i try to use it it does nothing

PHP:

<?php

namespace FlamingGenius\MessageSystem;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\utils\Config;
use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;

class main extends PluginBase implements Listener{

public function onEnable(){
  $this->saveDefaultConfig();
  $this->getServer()->getPluginManager()->registerEvents($this, $this);
}

public function onCommand(CommandSender $sender, Command $cmd, $label, array $args){
  $command = $cmd->getName();
  if($this->getConfig()->get("enabled") == "true"){
   if(strtolower($command == "broadcast")){
    $this->getServer()->broadcastMessage("broadcastteat");
   }
  }
  if($this->getConfig()->get("enabled") == "false"){
   $sender->sendMessage("Plugin is not enabled");
  }
}



}

?>

It should be $cmd->getName(), not $this->$cmd->getName(). Please try to acquire more knowledge of PHP before attempting to make a plugin.

I fixed that and now im getting this in the log

Spoiler: Error

Read the error. You have to implement Listener interface.

Uh...i do not know what this is

In the class declaration, you have to add `implements Listener`. And add the use statement for pocketmine\event\Listener.

If you look at my code u can see i already have this

Try making it Listener instead of listener?

Thats a typo on here the L is capital in my code

Add command in plugin.yml?

Already dOne that my plugin commands looks like this

PHP:

commands:
 broadcast:
  usage: /broadcast <msg>
  description: Broadcast a msg
  permission: ms.broadcast

OMG it has to be a string.

You don't need to use "" in YAML for most cases.
