  22. Flutter Web In developer preview Goal: Web support like mobile

    Not recommended for production yet Demos https://flutter.github.io/samples/
  23. Flutter Web Architecture

  24. What Works: - Build and serve websites with Flutter -

    Dart plugins - Loading custom fonts - Image assets and icons - Good UX just like in mobile - Chrome, Safari and Edge - Hot reload on debug - Minified JS on release KenKen by New York Times
  25. What is missing: - No text selection (!!!) - Poor

    accessibility - UI interaction is “mobile like” (e.g. no scroll) - Poor performance Dataviz Flutter web sample app
  26. Making our App Work Change to `channel master` Enable web

    with `config --enable-web` Adjust UI for large screen Run with `run -d chrome` …and it worked! kawaiitech.github.io/flutter-xmas
