Containerizing Flutter web apps with Docker

Software engineers often face challenges when deploying applications across different operating systems, which can lead to bugs and errors. While virtual machines were previously used to address these issues, they are slow and memory inefficient. Containerization, particularly through the use of Docker, offers a more efficient solution by packaging applications with their dependencies in isolated environments, ensuring consistent performance across various operating systems and infrastructures. Docker, a leading open-source tool for containerization, simplifies the orchestration of these containers and offers benefits such as cost efficiency, scalability, security, and ease of setup. The tutorial illustrates how to set up Docker and containerize a Flutter web application, highlighting the advantages of running applications independently from host server configurations, thus enhancing flexibility and reliability.
