While building web apps, deploying them is one of the most essential tasks — be it is for internal QA purposes, for staging, or production environments. Before releasing the Flutter web app, it is required to create a release bundle and a few of the best practices to release, which are explained here in detail.
From my experience of building and deploying Flutter web apps, I’m going to discuss the top 5 ways (step-by-step) to deploy Flutter web apps. They are:
The first way to deploy Flutter web apps is to host your Flutter web app on Firebase and here are the steps to do so-
Step 1: Create a project on Firebase console
Step 2: Download Firebase CLI
Step 3: Login via CLI, execute the command firebase login
Step 4: Choose Firebase “Hosting” for Flutter web app when asked for a feature
Step 5: Then, Select an existing Project
Step 6: Choose build/web as a directory & configure as a single-page app
f you see, File build/web/index.html already exists. Overwrite?
Then select NO. So it will not generate a default index.html file
Step 7: Deploy Flutter web to Firebase!
Another way to deploy Flutter web apps is using Github Pages and here are its steps-
Pre-requisites: Create a repo on Github.
Step 1: Use this pub
Execute the command
flutter pub global run peanut:peanut
Step 2: Flutter web-related files will be generated to the separate branch gh-pages (Don’t forget to push the branch origin)
Step 3: Change the GitHub pages source branch.
Go to: Repository → Settings → Options → Github Pages → Source branch: select gh-pages
Step 4: Flutter Web app will be deployed to Github
Pre-requisites: Create an account on https://www.netlify.com/
Step 1: Drag & Drop build/web folder to dashboard
Step 2: The web app will be deployed and the domain will be given to you.
Step 3 (Optional): The web app can be connected with the custom domain/subdomain.
Step 1: Use the same peanut pub
Step 2: Generate web-related files to the gh-pages branch
Step 3: Choose New site from git on the netlify dashboard
Step 4: Choose the repository & select branch to deploy
Step 4: Deploy Flutter Site to Netlify.
Step 1: Connect repository to https://codemagic.io/
Step 2: Go to Settings — Publish — Codemagic static pages
Step 3: Choose your custom subdomain
Step 4: Trigger a build, on the success, it will be deployed to:
Step 1: Log in to your AWS Management Console.
Step 2: Click on your user name at the top right of the page.
Step 3: Click on the Security Credentials link from the drop-down menu.
Step 4: Find the Access Credentials section, and copy the latest Access Key ID.
Step 5: Click on the Show link in the same row, and copy the Secret Access Key.
Step 6: Choose repo on codemagic
Step 7: Go to Settings — Publish — AWS S3 Bucket
Step 8: Fill the Access key ID, secret access Key, and Bucket name
Step 9: Trigger a build, on the success, it will be deployed to an S3 bucket
We have enough approaches to deploy/release a Flutter web app, that can be chosen for the QA environment as well as the production releases. Connecting it with CI/CD like Codemagic will reduce the repeating effort of manual deployments.
