    How to speed up front-end applications using Flutter and Server Side Rendering (SSR)

    How to speed up front-end applications using Flutter and Server Side Rendering (SSR)

    Flutter Web SSR (Server-Side Rendering) is an amazing tool that allows you to render your Flutter app on the server. This means that your app will be able to run on any platform that supports HTML, including the web, mobile devices, and even desktop apps.

    This is a huge advantage over traditional native apps, which can only be developed for specific platforms. With Flutter Web SSR, you can develop your app once and deploy it to any number of devices and platforms.

    There are two main benefits of using Flutter SSR:

    1. It allows you to reach a wider audience with your app.

    2. It makes your app more searchable and discoverable online.

    If you’re thinking of developing a Flutter app for the web, then you should definitely consider using Flutter Web SSR. It’s a great way to reach a wider audience and make your app more discoverable online.

    Server-side rendering for Flutter Web

    Flutter web support for server-side rendering (SSR) is still in its early stages, but it’s already possible to create a simple app that supports SSR.

    Flutter is a cross-platform framework that allows you to create amazing front-end applications. One of the great things about Flutter is that it can be used to create applications that run on both mobile and web.

    One of the key benefits of using Flutter for the web is that it supports Server Side Rendering (SSR). This means that your Flutter application can be rendered on the server, and then served to the client. This has a number of benefits, including:

    – reduced load times, as the initial page render is done on the server

    – improved SEO, as search engines can index the server-rendered content

    – better UX, as users can see content immediately while the app loads in the background

    To use Flutter for the web with SSR, you need to use the flutter_web package. This package provides all the necessary tools and libraries to create Flutter applications that can be run on the web.

    Here’s a simple example of how to use flutter_web with SSR:

    First, create a new Flutter project:

    $ flutter create myapp

    Next, add the flutter_web dependency to your pubspec.yaml file:


    flutter_web: any

    Then, update your main.dart file to use a MaterialApp widget:

    import ‘package:flutter/material.dart’;

    void main() => runApp(MyApp());

    class MyApp extends StatelessWidget {

    // This widget is the root of your application.


    Widget build(BuildContext context) {

    return MaterialApp(

    title: ‘Flutter Demo’,

    theme: ThemeData(

    primarySwatch: Colors.blue,


    home: MyHomePage(),




    Finally, update your pubspec.yaml file to include a new asset:


    – assets/index.html // <– new line

    This index.html file will be used as the entry point for your Flutter web application.

    Now, you can run your Flutter application on the web:

    $ flutter run -d web

    You should see the default Flutter application running in your browser.

    Congratulations! You’ve just created a Flutter application that can be rendered on the server using SSR. This is a great way to improve the load times and UX of your Flutter web apps.

    Remember to keep the following points in mind:

    – The flutter_webview package is still in beta and is subject to change.

    – Server-side rendering is not yet supported for all Flutter widgets. In particular, any widget that uses platform-specific code (e.g., CupertinoButton) will not work on the server.

    – If you’re using any third-party packages, make sure they are compatible with flutter_webview.

    Keep these points in mind and you should be able to create a basic SSR app with Flutter web. For more information, see the flutter_webview documentation.
