Overview
The functions_framework package enables developers to write portable Dart functions for Function as a Service (FaaS) environments. It provides a lightweight, consistent interface for creating serverless functions that can run across multiple platforms including Android, iOS, macOS, Windows, and Linux. Built by Google Cloud, it supports event-driven execution and integrates seamlessly with cloud hosting services. The framework simplifies the development of scalable backend logic without managing infrastructure. It is ideal for microservices, API endpoints, and automated workflows in cloud-native applications.
