The local database implemented in the provided Dart code is a simplified key-value store designed for local data storage. It consists of three main classes: LocalDatabase, LCR (Local Collection Reference), and LDR (Local Document Reference).

1. LocalDatabase:

- Represents the entire local database.
- Utilizes a base map (`base`) to store data.
- Provides methods for CRUD operations within the database.

2. LCR (Local Collection Reference):

- Represents a collection within the database.
- Offers methods to interact with documents within the collection.
- Supports operations such as adding, setting, updating, deleting documents, and obtaining all documents in the collection.

3. LDR (Local Document Reference):

- Represents a document within the database.
- Provides methods for CRUD operations specific to a document.
- Supports setting, updating, deleting, and retrieving data from the document.
- Allows referencing subcollections within the document.

Example:

void main() {
  final database = LocalDatabase();

  // Create new post (posts/post_id)
  database.collection("posts").document("post_id").set({
    "id": "post_id",
    "title": "My First Blog Post",
    "content": "This is my first ever blog post...",
    "author_id": "1",
    "category": "Technology",
    "tags": ["programming", "javascript"],
    "created_at": "2024-02-06T00:00:00Z",
    "updated_at": "2024-02-06T00:00:00Z",
    "published": true,
  });

  // Update post by id (posts/post_id)
  database.collection("posts").document("post_id").update({
    "title": "Updated Blog Post",
    "content": "This post has been updated!",
  });

  // Delete post by id (posts/post_id)
  database.collection("posts").document("post_id").delete();
  
  // Retrieve post by id (posts/post_id)
  database.collection("posts").document("post_id").get();
  
  // Retrieve all post (posts)
  database.collection("posts").get();
  
  // Create new post comment (posts/post_id/comments/comment_id)
  database.collection("posts").document("post_id").collection("comments").document("comment_id").set({
    "id": "comment_id",
    "post_id": "post_id",
    "content": "Great post!",
    "author_id": "2",
    "created_at": "2024-02-06T00:00:00Z",
    "likes": [],
    "dislikes": [],
  });

  // Update post comment by id (posts/post_id/comments/comment_id)
  database.collection("posts").document("post_id").collection("comments").document("comment_id").update({
    "content": "This is updated comment!",
  });

  // Delete post comment by id (posts/post_id/comments/comment_id)
  database.collection("posts").document("post_id").collection("comments").document("comment_id").delete();

  // Retrieve post comment by id (posts/post_id/comments/comment_id)
  database.collection("posts").document("post_id").collection("comments").document("comment_id").get();

  // Retrieve all post comments (posts/post_id/comments)
  database.collection("posts").document("post_id").collection("comments").get();
