The problem occurs when I am trying to regenerate the i18n files in Flutter's stock example app.
Following the README I run the following command:

flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/i18n  --generated-file-prefix=stock_ --no-use-deferred-loading lib/*.dart lib/i18n/stocks_*.arb

On Linux I got:

No @@locale or _locale field found in stocks_en, assuming 'en' based on the file name.
No @@locale or _locale field found in stocks_es, assuming 'es' based on the file name.

I suppose this is the expected output.

But on Windows I got:

Unhandled exception:
FileSystemException: Cannot open file, path = 'lib/*.dart' (OS Error: The filename, directory name, or volume label syntax is incorrect
, errno = 123)

I think the issue is just that on Windows you should use Windows path separators. e.g. the command should use lib*.dart and lib\i18n\stocks_*.arb

I afraid not. Using backslash results in the same error message:

C:\flutter\examples\stocks>flutter pub pub run intl_translation:generate_from_arb --output-dir=lib\i18n --generated-file-prefix=stock_ --no-use-deferred-loading lib\*.dart lib\i18n\stocks_*.arb

The command works when no wildcard is used, even with forward slash:

C:\flutter\examples\stocks>flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/i18n --generated-file-prefix=stock_ --no-use-deferred-loading lib/stock_strings.dart lib/i18n/stocks_en.arb
No @@locale or _locale field found in stocks_en, assuming 'en' based on the file name.

C:\flutter\examples\stocks>flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/i18n --generated-file-prefix=stock_ --no-use-deferred-loading lib/stock_strings.dart lib/i18n/stocks_es.arb
No @@locale or _locale field found in stocks_es, assuming 'es' based on the file name.

One problem is that passing individual files would not generate a "stock_messages_all.dart" with all discovered locales.

This has been tested in PowerShell and ordinary command prompt.

OK, it appears that the Windows shell is not expanding the wildcard, so we get a literal "*.dart" as the argument passed in to generate_from_arb.

What is it that doesn't work if you pass the individual files? I don't have easy access to a Windows machine, but passing in all the files explicitly on a Mac generates the files I'd expect.

I think I got you now. I tried to execute the command one by one, passing a single file each time. This way, only the locale found in the last executed command would be kept in main import file messages_all.dart.

Just discovered that I can indeed pass a list of files to the command line.

I can confirm this works for me:

flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/i18n --generated-file-prefix=stock_ --no-use-deferred-loading lib/stock_strings.dart lib/i18n/stocks_es.arb lib/i18n/stocks_en.arb

Thank you very much!

This should be in the docs https://flutter.dev/docs/development/accessibility-and-localization/internationalization#appendix-using-the-dart-intl-tools

I agree, this should be in the docs. I ran into this issue while moving through the standard introductory documentation. Having a buggy experience getting essential Flutter functionality running for an app was a big turn off as I was experimenting with the framework.

instead of passing a list of files you can call the wildcard by passing this argument instead.

flutter pub pub run intl_translation:generate_from_arb --output-dir=lib/i18n --generated-file-prefix=stock_ --no-use-deferred-loading (Get-ChildItem lib/*.dart) (Get-Childitem lib/i18n/stocks_*.arb)

this worked for me pretty well.

I wish the input files could ignore (all the files in lib could be passed as default). And provide platform independent solution. It should not difficult.

I tried to add glob path parser support for this lib. see dart-archive/intl_translation#92.
