Errors: Type 'AuthenticatorStep' not found and 'AuthenticatorStep' isn't a type. #2594

Closed stouvoli closed 1 year ago

Description

Running my application is not working. I get error message below saying 'AuthenticatorStep' not found and 'AuthenticatorStep' isn't a type. I have setup localization and it is working fine except when I add the line below in the arb file.

  "@backTo": {
    "description": "Label of button to return to the previous step",
    "placeholders": {
      "previousStep": {
        "type": "AuthenticatorStep",
        "example": "signIn",
        "description": "The title of the previous step."
      }
    }
  },

The amplify_authenticator package is apparently correctly configured but the AuthenticatorStep enum is not visible from the generated arb files .dart_tool/flutter_gen/gen_l10n/app_localizations.dart, .dart_tool/flutter_gen/gen_l10n/app_localizations_en.dart and .dart_tool/flutter_gen/gen_l10n/app_localizations_en.dart.

Steps to Reproduce

  1. Create a flutter app and setup amplify as explained on doc https://docs.amplify.aws/start/q/integration/flutter/.
  2. Add dependecies: 
    cupertino_icons: ^1.0.2
amplify_flutter: ^0.6.10
amplify_datastore: ^0.6.10
amplify_auth_cognito: ^0.6.10
amplify_api: ^0.6.10
amplify_storage_s3: ^0.6.10
amplify_authenticator: ^0.2.4
url_launcher: ^6.1.7
http: ^0.13.5
  3. Activate localization as explained here: https://docs.flutter.dev/development/accessibility-and-localization/internationalization
  4. Configure amplify login as explained here: https://ui.docs.amplify.aws/flutter/connected-components/authenticator/configuration
  5. Configure amplify login localization as explained here: https://ui.docs.amplify.aws/flutter/connected-components/authenticator/customization#internationalization-i18n
  6. Update the arb file with line below: 
    "backTo": "Retour à {previousStep, select, signUp{Sign Up}, signIn{Sign In}, confirmSignUp{Confirm Sign-up}, confirmSignInMfa{Confirm Sign-in} confirmSignInNewPassword{Confirm Sign-in} sendCode{Send Code} resetPassword{Reset Password} verifyUser{Verify User} confirmVerifyUser{Confirm Verify User}}",
"@backTo": {
"description": "Label of button to return to the previous step",
"placeholders": {
  "previousStep": {
    "type": "AuthenticatorStep",
    "example": "signIn",
    "description": "The title of the previous step."
  }
}
},

    Try to run the app.

Hello, Nobody to help on this?

dnys1 commented 1 year ago

Hi @stouvoli - apologies for the late reply. In order for this type to be visible to your localizations, can you please try adding the following to your l10n.yaml file:

header: |
  import 'package:amplify_authenticator/amplify_authenticator.dart';

Alternatively you can pass this as a flag to the flutter gen-l10n command:

$ flutter gen-l10n \
    --header="import 'package:amplify_authenticator/amplify_authenticator.dart';" \
    # ... other params

Hello @dnys1,

Thanks for your reply. I have just checked my project. I see today another error message no more related to enum AuthenticatorStep. I do not know why but this enum is now visible from the project files. The new error is related to a syntaxe error in the Autenticator package buttons_en.arb file. The select statement is not correct. But I can solve this one. Thanks

"backTo": "Back to {previousStep, select, signUp{Sign Up}, signIn{Sign In}, confirmSignUp{Confirm Sign-up}, confirmSignInMfa{Confirm Sign-in} confirmSignInNewPassword{Confirm Sign-in} sendCode{Send Code} resetPassword{Reset Password} verifyUser{Verify User} confirmVerifyUser{Confirm Verify User}}", "@backTo": { "description": "Label of button to return to the previous step", "placeholders": { "previousStep": { "type": "AuthenticatorStep", "example": "signIn", "description": "The title of the previous step." } } },
