Deploy flutter on web

Please check the offical documentation:

• Build a flutter web app
• Deploy a flutter web app

Basically flutter web will create a build/web folder, which contains all the files needed to deploy on web. It contains an index.html file, which is the entry point of the web app. As this is a web app it must be run as a single page application, so the server must be configured to redirect all the requests to the index.html file.

Deploy your flutter web app on firebase

Install firebase tools

npm install -g firebase-tools

Login to firebase

firebase login

Init firebase

firebase init

Firebase will ask you which features you want to use, select hosting. It will also ask if you want to host this app as a single page application, select yes.

Deploy

firebase deploy --only hosting
