Why is assetManager empty in view?

Question

Yii

In layout in Yii::$app->assetManager->bundles I can see all connected resources.
But in the view that is rendered through this layout Yii::$app->assetManager->bundles is empty. Why?
How can I define the baseUrl in the view if I include resources in the layout in this way?

$asset = app\modules\admin\components\AdminAsset::register($this);

Connect your resource in the view. Don't worry, it won't connect a second time.
$asset = app\modules\admin\components\AdminAsset::register($this);
everything here is $asset->baseUrl
