Flutter_file_picker: Support for MacOS & Windows Desktop

[JayPerfetto]

I get a platform exception trying to use this in a flutter app deployed to MacOS, but it works on android and iOS. Are there any plans to extend support to native mac / desktop?

Thanks!

This plugin already has Desktop support through Flutter Go. You may want to take a look.

As Flutter Desktop itself is on a really early stage, I don’t have plans for it right now and it’s a low priority feature. However, support for Flutter Web is being added in the next days.

Thanks!

[miguelpruivo]

Good news is I added support to file_picker_web (check the web-support branch) using Flutter's team approach for multiple platform support. This actually opens the possibility to easily add support to MacOS Desktop as well, so this actually may be a feature in a near future.

@miguelpruivo Could you provide some hints, what would be necessary to add support for macOS? The NeoSEALs team is happy to provide a respective PR 🚀

nothing helpful, just reminder that it does not work with macos

Hi guys, it's pretty clear at this moment that this plugin doesn't support MacOS (only through Flutter go). Otherwise I'd have added it on supported features.

This might come in a feature, but for the time being, there are other priorities in the line.

Thank you!

[miguelpruivo]

Support for MacOS should now be an easy go since file_picker 2.0.0, because all platforms are now merged.

Looking forward it as soon as I have time, but feel free to issue a PR if you have any chance.

I'm testing now, but getting MissingPluginException

Do I need do something more to work on mac desktop?

[miguelpruivo]

@Katekko it's not yet implemented.

For now, you can use Go implementation, which is supported by MacOS (and all other desktop platforms).

I sorry.

So I just need follow the instructions on readme?

[miguelpruivo]

@Katekko yes, just follow this but you'll need to use file_picker: 1.13.3 as of now until #382 is resolved.

I have tested a sample application for selecting files in Flutter Windows desktop. Only "Select folder" function works (including a couple of fixes)

[vware]

Flutter support for desktop has matured a lot since may, are there any plans to support desktop OSs natively by now?

[miguelpruivo]

@vware might be a possibility yes. However currently I don’t have a windows machine so it won’t be easy to test it out on all three.

[vware]

thanks for the quick reply. just in case people look for a google-ish interim solution, there is a plugin that's part of the flutter desktop embedding effort:

file_chooser:
git:
url: git://github.com/google/flutter-desktop-embedding.git
path: plugins/file_chooser
ref: INSERT_HASH_HERE

[jlubeck]

Just adding my support for this feature. I would love to help but have no idea how flutter plugins work. Is there anyway I can help?

[jlubeck]

Was this supposed to be fixed by https://github.com/miguelpruivo/flutter_file_picker/issues/382 or is that something else?

[rachmatg]

Try this on M1 based MacOS, it works, just got null path.

FilePickerResult result = await FilePicker.platform.pickFiles();
          if (result != null) {
            //File file = File(result.files.single.path);
            print(result.files.map((e) => e.path).toString());
            print(result.files.single.name);
          } else {
            // User canceled the picker
          }

This feature would be very useful, I had to remove this package from my project and use filepicker_windows or file_picker_cross analyzing which, Flutter go limited me a lot.
