Integrating Flask and Flutter apps

Building a full-stack application typically involves separating the frontend and backend components, which communicate through mechanisms like REST, SOAP, or GraphQL. In this context, Flutter, an open-source tool developed by Google, is used for creating cross-platform frontend applications, while Flask, a Python framework, serves as the backend. The tutorial outlines how to integrate a Flutter frontend with a Flask backend using a to-do app as an example. The frontend communicates with the backend by sending HTTP requests to perform operations such as creating, executing, and deleting tasks stored in a database. The Flask backend uses SQLAlchemy and Marshmallow for database management and serialization, while the Flutter app uses the Provider package for state management and HTTP package for network communication. The tutorial demonstrates the broader principles of frontend-backend integration through RESTful APIs, applicable to various frameworks, and includes steps to set up and test the application.
