It looks like you may need to install the Flutter extension from https://marketplace.visualstudio.com/items?itemName=Dart-Code.flutter. Please let us know if the error still comes up after you have installed the extension. Thanks!

@lisa-liao
I'm coding on Android Studio, not the Visual Studio Code.
I try installing the package with pub get it result is OK no any error.

I think cause from intl.dart package and if cannot find bidi_utils.dart (I don't know what is it)

The issue may be similar to this. Please follow the accepted answer, and let us know if the issue still remains. Thanks!

Not work.
I follow them step. I got an error about this

flutter/.pub-cache/hosted/pub.dartlang.org/intl-0.15.8/lib/src/intl/bidi_formatter.dart:68:28: Error: The getter 'TextDirection' isn't defined for the class 'BidiFormatter'.
 - 'BidiFormatter' is from 'package:intl/intl.dart' ('path/to/flutter/.pub-cache/hosted/pub.dartlang.org/intl-0.15.8/lib/intl.dart').
Try correcting the name to the name of an existing getter, or defining a getter or field named 'TextDirection'.
      : contextDirection = TextDirection.LTR,
                           ^^^^^^^^^^^^^

@squalltua , have you rebooted your machine since the problem occurred? (I know it's a non-engineering suggestion but it works for far too many engineering problems!)

[squalltua]

@willlarche yes

[lisa-liao]

@squalltua Can you try deleting all downloaded pub packages and re-installing with flutter packages get? Also make sure that the pubspec.yaml file in your app folder
is the same as https://github.com/material-components/material-components-flutter-codelabs/blob/104-complete/mdc_100_series/pubspec.yaml. Thanks!
