我创建了一个名为的事件UserWalletNewTransaction.php并将其添加到其中：
public $transaction;
public function __construct($transaction) {
$this->$transaction = $transaction;
}
并在以下位置注册EventServiceProivder.php：
use App\Listeners\UserWalletNotification;
protected $listen = [
UserWalletNewTransaction::class => [
UserWalletNotification::class,
],
现在为了在控制器上触发这个事件，我编写了这个代码：
$newTransaction = UserWalletTransaction::create(['user_id' => $user_id, 'wallet_id' => $wallet_id, 'creator_id' => $creator_id, 'amount' => $amount_add_value, 'description' => $trans_desc]);
event(new UserWalletNewTransaction($newTransaction));
然后在 Listener 中UserWalletNotification.php，我尝试了：
public function handle(UserWalletNewTransaction $event) {
dd($event->transaction);
}
但它null以某种方式返回。
但是，如果我dd($event)改为，我会得到：
那么这里出了什么问题呢？我可以正确插入新记录，user_wallet_transactions并且变量$newTransaction应该包含transaction信息，但事实并非如此。
这也是模型UserWalletTransaction.php：
protected $fillable = ['user_id','wallet_id','amount','description','creator_id'];
protected $table = 'user_wallet_transactions';
我真的很感激你们关于这个的任何想法或建议......
提前致谢。
更新#1：
如果我dd($newTransaction)之前在控制器上做event()，我会得到这个：
更新#2：
这是事件的完整代码，UserWalletNewTransaction.php：
class UserWalletNewTransaction
{
use Dispatchable, InteractsWithSockets, SerializesModels;
/**
* Create a new event instance.
*
* @return void
*/
public $transaction;
public function __construct($transaction)
{
$this->$transaction = $transaction;
}
}
更新#3：
以下是dd($event)监听器的完整结果：
