Flutter for web Tech Preview FAQ

Why can't I import package:flutter?

Our goal is to enable building applications for mobile and web simultaneously from a single codebase. However, to facilitate fast experimentation, temporarily Flutter for web is developed in a separate namespace. So, as of today, in order to use Flutter for web you need to import package:flutter_web instead of package:flutter, and package:flutter_web_ui instead of dart:ui.

Why can't I use existing Flutter pub packages?

Due to the temporarily limitation explained in "Why can't I import package:flutter?" above it is not possible to use existing Flutter packages published on https://pub.dev. This is because those packages import package:flutter.

Can I use plugin X on the web?

Plugin support for the Web is currently in design stage. Please, stay tuned. In the meantime, you can use libraries listed on https://api.dartlang.org to access browser API.

Why are fonts not working?

Until Flutter for web is integrated into the Flutter SDK we do not automatically bundle fonts as part of the build process. In the meantime, you need to follow the instructions for including the fonts in the migration guide.

When will Flutter for web be ready for production?

Production readiness greatly depends on your use-case. We plan to listen to community feedback to decide which parts to make production-ready first. While we cannot predict the future, here are a few things we know we need to finish:

  • Merge into the Flutter SDK.
  • Make sure widgets are rendered correctly in all important use-cases.
  • Make sure performance is great for most use-cases.
  • Finish our accessibility work.

How do I make network requests?

Due to browser limitations dart:io is not supported on the Web. In the meantime you can use package:http to make HTTP requests. This package works both in Flutter for mobile and in Flutter for web.
