You need to override protected function attemptLogin(Request $request) method from \Illuminate\Foundation\Auth\AuthenticatesUsers Trait in your LoginController i.e. in my LoginController class

protected function attemptLogin(Request $request) {

    $identity = $request->get("usernameOrEmail");
    $password = $request->get("password");

    return \Auth::attempt([
        filter_var($identity, FILTER_VALIDATE_EMAIL) ? 'email' : 'username' => $identity,
        'password' => $password
    ]);
}

Your LoginController class should use Trait \Illuminate\Foundation\Auth\AuthenticatesUsers in order to override attemptLogin method i.e.

class LoginController extends Controller {

     use \Illuminate\Foundation\Auth\AuthenticatesUsers;
     .......
     .......
}
