You need to create two classes. First class should to implements SitemapSourceInterface, SitemapItemInterface and second class should implement SitemapItemInterface:

<?php

use app\modules\posts\models\Posts;
use prokhonenkov\sitemapgenerator\interfaces\SitemapItemInterface;
use prokhonenkov\sitemapgenerator\interfaces\SitemapSourceInterface;
use samdark\sitemap\Sitemap;
use yii\helpers\ArrayHelper;
use yii\helpers\Url;

class PostsSitemap extends Posts implements SitemapSourceInterface, SitemapItemInterface
{
	public function getSitemapItems(): array
	{
		return ArrayHelper::merge([new PostsSitemapItem()], self::find()->all());
	}

	public function getSitemapName(): string
	{
		return 'posts';
	}

	public function getLastModified(): int
	{
		return strtotime($this->updated_at);
	}

	public function getLocation($index = null): string
	{
		return Url::to(['/posts/view', 'id' => $this->id], true);
	}

	public function getChangeFrequency(): string
	{
		return Sitemap::MONTHLY;
	}

	public function getPriority(): string
	{
		return 0.5;
	}
}

<?php

use app\modules\posts\models\Posts;
use prokhonenkov\sitemapgenerator\interfaces\SitemapItemInterface;
use samdark\sitemap\Sitemap;
use yii\helpers\Url;

class PostsSitemapItem extends Posts implements SitemapItemInterface
{
	public function getLastModified(): int
	{
		return strtotime( Posts::find()
			->max('updated_at'));
	}

	public function getLocation($language = null): string
	{
		\Yii::$app->language = $language;
		return Url::to(['/posts/index'], true);
	}

	public function getPriority(): string
	{
		return 1;
	}

	public function getChangeFrequency(): string
	{
		return Sitemap::DAILY;
	}
}

Usage

Put this code in your ActiveRecord model in afterSave method:

public function afterSave($insert, $changedAttributes)
{
    parent::afterSave($insert, $changedAttributes);
    \Yii::$app->sitemap->generate();
}

Eventually will be created a structure of files:
