Is there a validation rule for the size of the uploaded file?

Question

Yii

I uploaded pictures, but there is not enough check for size.
Is there already a validation rule for file size that could be added to the rules:

public function rules()
    {
        return [
            [['imageFile'], 'file', 'extensions' => 'jpg, png, gif'],
        ];
    }

I know that you can connect fancy modules for processing pictures and files, or that you can write a check by hand on the property of the UploadedFile object. But the question is exactly how to do it simply and with the built-in features of Yii2.
Answer:

public function rules()
    {
        return [
            [['imageFile'], 'file', 'extensions' => 'jpg, png, gif', 'maxSize' => 1000000],
        ];
    }

Are you kidding me? Is it difficult to open documentation?

The maxSize parameter!
