set dialog language

[mrudigier]

Hi,

I am using the file_picker on macos (Monterey 12.5) with the system language/locale set to german.
Im using the following code to chose an image file:

FilePickerResult? result = await FilePicker.platform.pickFiles(
      allowMultiple: false,
      lockParentWindow: true,
      type: FileType.custom,
      allowedExtensions: AllowedAttachmentFileTypes.allowedFileExtension(),
    );

When the file picker window opens, the language of the dialog is a mix of german and english, e.g. it says "Cancel" on the cancel button, but "Auswählen" on the confirmation button.

I don't see a direct way to set the language for the file picker. Is it possible to allow this?

Hi @mrudigier, unfortunately, file_picker for macOS is based on an approach with limited options. It works by executing a shell command named osascript, which can execute AppleScript commands. For picking files, we simply execute:

osascript -e "choose file"

Here you can find the man pages of osascript. From Apple's documentation it looks like the choose file command has no option to configure the language. Therefore, file_picker does not offer this option. If you can find a way to change the language/text of the buttons through osascript, then let us know.

You could also try the official Flutter plugin named file_selector (https://pub.dev/packages/file_selector) with a native approach instead of executing shell commands.

Hi @philenius, thank you very much for your reply. I will check out the file_selector package.
