Flutter supports working with databases like SQLite and Cloud Firestore through dedicated packages and plugins, allowing seamless integration of persistent storage in apps.

For SQLite, Flutter uses the sqflite plugin, which provides a simple API for performing CRUD operations on a local SQLite database. Developers can define schemas, run raw SQL queries, and manage transactions. SQLite is ideal for offline-first apps that need structured, relational data storage.

To use SQLite in Flutter:

1. Add sqflite and path_provider packages.

2. Initialize the database using openDatabase().

3. Create tables and perform operations like insert, query, update, and delete.

For Cloud Firestore, Flutter uses the cloud_firestore plugin, which connects to Google’s NoSQL document database. It supports real-time data syncing, offline support, and scalable data storage in key-value/document format.

Firestore is well-suited for apps that require:

• Real-time updates

• Cloud-based data sharing

• Integration with Firebase Authentication and other Firebase services

To use Firestore:

1. Add cloud_firestore to the pubspec.yaml.

2. Initialize Firebase in the app.

3. Access collections and documents via Firestore's structured API.

Both options have use cases depending on app needs—SQLite for local and structured storage, Firestore for cloud-based, scalable real-time apps. Flutter’s plugin ecosystem makes integrating both straightforward and efficient.
