await model.load("This is the text and url: https://google.com.");

// Check if it has the preview data and save it to database.
if (model.hasData) {
    await database.save(
        previewUrl: model.firstLink,
        previewTitle: model.title,
        previewDescription: model.description,
        previewImageUrl: model.image,
    );
}
