Can I plant directly into a bag of soil?

Excuse me, I'm curious about something regarding gardening practices. Could you please clarify for me if it's advisable to plant directly into a bag of soil? I've heard mixed opinions on this, and I'm wondering if there are any potential drawbacks or benefits to this approach. For instance, would the soil in the bag retain enough moisture and nutrients for the plants to thrive, or would it be more prone to drying out and becoming compacted? Additionally, are there any specific types of bags or soils that work better for this method? Thank you for your insight.
