Flutter For Backend Developers Interview Question
Flutter is a mobile app development framework that can be used by backend developers to create cross-platform apps with a single codebase. This is especially useful for backend developers who want to build mobile apps without having to learn a new programming language or framework. Flutter apps are also known for their high performance and low memory usage, which makes them ideal for building resource-intensive apps.
