Declaration of ... must be compatible with - yii

Question

I'm using this Yii2 plugin for my user model
https://yii2-usuario.readthedocs.io/en/latest/
In my main.php i have this.
'user' => [
'class' => Da\User\Module::class,
'enableEmailConfirmation' => true,
'classMap' => [
'User' => 'app\models\user\Model\User',
'SocialNetworkAccount' => 'app\models\user\Model\SocialNetworkAccount',
],
then in the directory models/user/Model i have this
namespace app\models\user\Model;
use Yii;
use app\models\user\Model\User;
use Da\User\Model\SocialNetworkAccount as BaseClass;
class SocialNetworkAccount extends BaseClass
{
public function connect(User $user)
{
return $this->updateAttributes(
[
'username' => null,
'firstname' => $user->firstname,
'lastname' => $user->lastname,
'email' => null,
'code' => null,
'user_id' => $user->id,
]
);
}
}
but when i go to my login page i get this error
Declaration of app\models\user\Model\SocialNetworkAccount::connect(app\models\user\Model\User $user) must be compatible with Da\User\Model\SocialNetworkAccount::connect(Da\User\Model\User $user)
i tried following the tutorial here to override classes, but no luck
https://yii2-usuario.readthedocs.io/en/latest/enhancing-and-overriding/overriding-classes/
what am i doing wrong here? thanks
UPDATE:
i tried this
public function connect(\Da\User\Model\User $user)
don't get the error anymore, but now i noticed it doesn't add firstname and lastname
in my user model rules i have this
public function rules()
{
return [
...
[['email', 'firstname', 'lastname'], 'safe'],
]
}

From what you've described it looks like usuario is using DI container to create the User class instance when calling the connect() method.
When overriding it you have to follow the rule that preconditions cannot be strengthened in a subtype. That means that you can't typehint the parametr with the subclass of what the original method uses as its parametr. Your connect method definition must look like what you've posted in your question:
public function connect(\Da\User\Model\User $user)
But because of that, the dependency injector is creating an instance of Da\User\Model\User when calling connect() method. So, what you've missed is setting the DI container to create instance of app\models\user\Model\User whenever it's supposed to create instance of Da\User\Model\User like this:
'container' => [
'definitions' => [
Da\User\Model\User::class => app\models\user\Model\User::class,
],
],
Of course, for this to work your app\models\user\Model\User class must extend the Da\User\Model\User class.
There is a complete example how to override usuario's User model in usuario's documentation
