[Question] Where to handle TimeStamp to DateTime conversion?

I was wondering where is the best place to handle converting a todo entity from firestore?
- If i added a `Todo.fromFirestore` method, then the repository_core would have a cloud_firestore dependency.

Start by reading the Todo entity and repository_core references mentioned in the question, then trace where Firestore data enters the application. The issue does not specify a requested code change or a test, so done would require an agreed conversion boundary and a documented implementation plan.
