![]() Set up Flutter - Flutter will be installed and set up in the container.Install Dependencies - The Debian image will be set up and relevant packages installed.We will use a Dockerfile to specify our container. Set up a Docker Container to Serve the App ![]() Although I haven’t explored it further, I am sure some pretty cool stuff could be done using this technique.Īt this point, we have convinced ourselves that all of the magic has been taken care of by Flutter and that all we need to do to serve the app is serve this build directory. This is incredibly neat because a user could actually embed the Flutter app anywhere in any standard html page and serve it how they like. Make sure to inspect the index.html file and notice that it specifies the script source to be. This entire web directory needs to be served together. After this is done you will see a new folder in the build directory in the project called web:Īs you can see this looks sort of like a release folder for a standard web site. Let’s convince ourselves of this by building our Flutter web app with flutter build web while in the project directory. Test that you can run your Flutter web app locally by:Ī Flutter app on the web is eventually translated down to HTML and Javascript.flutter create flutter_web_docker_example.As a general tip for reading new technical guides I always recommend that the reader reads the entire guide before following any setup steps. I assume the reader is using Linux but the information is easily adapted to other platforms. However, in the spirit of helpfulness I will include links to important materials. Therefore, I assume basic knowledge of Docker, Flutter, and web development basics. I am fairly sure that someone who stumbles across this article will have been looking for it. After figuring out how to do it on my own I wanted to share it with the world, which is the purpose of this article. I wanted to serve my front end Flutter app just like any other front end from within a container but I couldn’t find any direct literature on doing this. In my own development, I am building an app designed around microservices that will eventually be deployed with Kubernetes. ![]() Because Flutter for web is so new, users are discovering new ways of doing things all the time. The main thing that is different is how the app is served and deployed. ![]() From an experience and functionality point of view, developing a Flutter app for the web is almost exactly the same as for any of the other platforms. However, a number of organizations are already using it successfully for production sites. Flutter for Webįlutter’s support for the Web is still in the Beta stage of development. Luckily, Google has offered us Flutter as a promising candidate to bring about the reality of a truly crossplatform development experience. These included a lack of support from certain major corporations, performance issues, and security issues. Java was one of the first technologies that attempted to solve this problem but it was stymied by a number of challenges. Paying for 3 different engineering teams to support one product is an expensive proposition. Traditionally, if an organization wanted to support their application on web, mobile, and desktop it would have to support 3 separate codebases all in different languages and using different technologies. Writing a single codebase that runs on many platforms offers a number of advantages. It represents the most recent effort towards what Java promised: a “Write Once, Run Anywhere” experience. Flutter is a UI toolkit for building natively compiled applications for mobile, web, and desktop platforms with a single codebase.
