Flutter for Web: How to Deploy a Flutter Web App?

With the stable release of Flutter 1.12, Flutter for web is now in the beta channel. But ahead of a beta release, the community has already started building for Flutter web.

While building web apps, deploying it 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 apps, I'm going to discuss the Top 5 (IMO) Ways to Deploy Flutter Web Apps. They are:

  1. Firebase Hosting

  2. Github Pages

  3. Netlify

  4. Codemagic Static Pages

  5. AWS S3 (through codemagic)

#1: Firebase Hosting

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 "Hosting" 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


If 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!

firebase deploy


#2: Github Pages

Pre-requisites: Create a repo on Github.

Step 1: Use this pub

peanut | Dart Package

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: Web app will be deployed to


#3: Netlify

Pre-requisites: Create an account on https://www.netlify.com/

Approach 1:

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.

Approach 2:

Step 1: Use the same peanut pub

peanut | Dart Package

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 Site.

#4: Codemagic Static Pages

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:


#5: Deploy on AWS S3 (via Codemagic)

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.
