I am unable to build my flutter web project

When trying to run flutter build web i get "build web" is not currently supported. I had previous errors where i was stuck with Dart 2.5.0-dev.4.0.flutter-be66176534 and required 2.5.0 or higher, this has now been solved but i am unable to build my project.

flutter doctor -v

I have tried

• re-installing dart
• re-installing flutter
• re-installing Visual Studio code
• copy file contents to a new web project (same error)

I couldn't find any information on what this is caused by and how to resolve it online

What can i do to resolve this error?

Solution 1:

Please once do configure like below

1. flutter channel stable
2. flutter upgrade
3. flutter config --enable-web
4. cd into project directory
5. flutter create .
6. flutter run -d chrome

Solution 2:

So currently you are at stable channel . You have to switch to the beta channel as flutter web is not at a stable channel right now. In order to make it working run the following commands in the terminal.

1. flutter channel beta
2. flutter upgrade

3. flutter config --enable-web.

   After that restart your IDE and build the web app.
