Introduction:

In this article, we will explore how to enable hot reload for Flutter web in its beta release, enhancing the development process by allowing real-time updates without restarting the application.

Note:

If you want to learn the difference between hot reload and hot restart, watch this video.

Steps:

• Open up terminal and switch to beta channel using below command.

    flutter channel beta
  

• Execute below command to get the latest update available on beta channel.

    flutter upgrade
  

• Make sure you have the version 3.31 or above installed on your machine.

• Open up Flutter project in VS Code.

• Now run the Flutter project by executing below command in terminal.

    flutter run -d chrome --web-experimental-hot-reload
  

• --web experimental-hot-reload is the new flag that we need to add to enable hot reload in beta for Flutter web.

• After running the application, make a UI change and hit r in terminal to reload the change in Flutter web application.

• Or just add the below configuration in launch.json file and hit F5 to run the application.

        {
                "name": "Flutter for web (hot reloadable)",
                "type": "dart",
                "request": "launch",
                "program": "lib/main.dart",
                "args": [
                  "-d",
                  "chrome",
                  "--web-experimental-hot-reload",
                ]
            }
  

• Your Flutter application is now running with hot reload enabled for Flutter web in beta. This means faster iterations and smoother development process.
