title: getDirectoryPath() throws an exception in Flutter on Windows Desktop

labels: windows, desktop, go

Describe the bug
I'm developing a Flutter app for Windows desktop and I experience the exact same exception. The function FilePicker.getDirectoryPath() throws an exception and no file picker dialog is shown. A simple flutter clean and flutter build, as described in the issue template, with the latest file_picker version ^1.13.3 doesn't help.

var filePath = await FilePicker.getDirectoryPath();

Error Log

Whereas the function getFilePath() works as expected and opens Window's file picker dialog (awesome :thumbsup:):

var filePath = await FilePicker.getDirectoryPath();

I’m sorry, picking directories isn’t fully supported on Desktop versions.

miguelpruivo on 22 Aug 2020

Oh, I'm sorry, I kind of missed that. Thank you for your quick response.

philenius on 22 Aug 2020

@philenius no problem! Feel free to add it If you had the time, and issue a PR with it.

Alright, I cloned your repository and executed the example Flutter app located in ./file_picker/example. I enabled Windows desktop support in Flutter like this:

flutter create --platforms=windows .

Surprisingly, FilePicker.getFilePath() and FilePicker.getDirectoryPath() both worked on Windows. Obviously, there's no need to implement the feature of picking a directory.

On the other side, in my own Flutter app I would still get an exception when calling the latter function. So, I changed the dependencies of my own Flutter application to reference your repository which I cloned to my local disk (master branch, latest commit fa80ef6132510b90b77d2b812f4a4b2d2fcef64b).

My pubspec.yaml now looks like this:

dependencies:
 file_picker:
   path: ../go/src/flutter_file_picker/file_picker

I figured out that I need to delete the ./go directory of my Flutter app:
```
rm -r ./go/
```

Then initialize hover again:

$ hover init

hover:          dev:       Plugin replaced in go.mod to path: '../go/src/flutter_file_picker/file_picker'
hover: run `hover plugins get` to import the missing plugins!

Hover than advises to call hover plugins get.

Finally, execute hover run:

It works! I can select a directory.

Conclusion: I can't get it working with file_picker version 1.13.3 that has been published to pub.dev. But, it works when I clone your repository to my computer and reference it in pubspec.yaml.
I don't understand what's happening but I suspect a version mismatch or anything alike. I can see some differences in the local ./go directory that is created by hover:

The statement for importing file_picker in ./go/options.go is different.
The referenced version of file_picker in ./go/mod.go is different.

Working version with dependency on locally cloned file_picker repository

pubspec.yaml:

dependencies:
  file_picker:
    path: ../go/src/flutter_file_picker/file_picker

./go/options.go:

package main

import (
    "github.com/go-flutter-desktop/go-flutter"
    file_picker "github.com/miguelpruivo/plugins_flutter_file_picker/go"
)

var options = []flutter.Option{
    flutter.WindowInitialDimensions(800, 800),
    flutter.AddPlugin(&file_picker.FilePickerPlugin{}),
}

./go/go.mod:

module myapp/go

go 1.15

require (
    github.com/go-flutter-desktop/go-flutter v0.41.2
    github.com/miguelpruivo/plugins_flutter_file_picker/go v0.0.0-00010101000000-000000000000
    github.com/pkg/errors v0.9.1
)

replace github.com/miguelpruivo/plugins_flutter_file_picker/go => C:\Users\phil\workspace\go\src\flutter_file_picker\file_picker\go

Not working version with dependency on package that has been published to pub.dev

pubspec.yaml:

dependencies:
  file_picker: ^1.13.3

./go/options.go:

package main

import (
    "github.com/go-flutter-desktop/go-flutter"
    file_picker "github.com/miguelpruivo/flutter_file_picker/go"

var options = []flutter.Option{
    flutter.WindowInitialDimensions(800, 800),
    flutter.AddPlugin(&file_picker.FilePickerPlugin{}),

philenius on 22 Aug 2020

@philenius thank you for your detailed information on this. That’s really weird actually, since you are using the same version anyway. May be some caching issue, but I’ll definitely see if I can do anything about it.

miguelpruivo on 22 Aug 2020

@philenius I've been looking into this and I actually don't get why would go.mod change for a different tag and also why you need to reference plugins_flutter_file_picker instead. This repo was once called plugins_flutter_file_picker but it's been a while (months if not more than a year!) that it was renamed to just flutter_file_picker.

Also, as some others use go for their own projects and never complained about this, leads me to think that in fact there could be a caching issue on your end. Do you have the chance to try it on a different machine?

Thanks!

miguelpruivo on 23 Aug 2020

@miguelpruivo thank you for looking into this. I have set up a virtual machine with a fresh Windows installation and repeated all steps. Unfortunately, I cannot execute hover run due to the missing support of OpenGL in VirtualBox:

$ hover run
hover: ΓÜá The go-flutter project tries to stay compatible with the beta channel of Flutter.
hover: ΓÜá     It's advised to use the beta channel: `flutter channel beta`
hover: Building flutter bundle
hover: Using engine from cache
hover: Compiling 'go-flutter' and plugins
hover: Successfully compiled executable binary for windows
hover: Build finished, starting app...
hover: Running myapp in debug mode
creating glfw window: APIUnavailable: WGL: The driver does not appear to support OpenGL
hover: App 'myapp' exited with error: exit status 1

Tomorrow, I'll retry on a different computer, this time without virtualization. I'll keep you posted!

philenius on 25 Aug 2020

Okay, I tested it on a second Windows 10 computer (physically different computer than the last one that I tried it on). I went through all installations, created the demo app, and ran the app. I even repeated the whole process on my Ubuntu and I got the exact same results.

From the console output, I can see that the referenced versions of miguelpruivo/flutter_file_picker/go are different. Version v0.0.0-20200604215027-87ee48b7f3f6 throws an exception. Version v0.0.0-00010101000000-000000000000 does not throw an exception when calling FilePicker.getDirectoryPath(). Are these versions actually different because they both start with v0.0.0?

If I replace the dependency in pubspec.yaml with a local reference to the cloned repository and re-initialize hover like so, then I can use the FilePicker.getDirectoryPath() without an exception:

rm -rf ./go
hover init

Hover automatically creates the file ./go/cmd/import-file_picker-plugin.go and automatically selects the following version for flutter_file_picker:

...
require (
    ...
    github.com/miguelpruivo/plugins_flutter_file_picker/go v0.0.0-00010101000000-000000000000
    ...
)
...

In this case, hover advises me to execute hover plugins get separately. Console output:

phil@DESKTOP-QNEFKC2 MINGW64 ~/workspace/myapp
$ hover init
go: creating new go.mod: module myapp/go
hover: You can add the 'C:\Users\phil\workspace\myapp\go' directory to git.

In contrast to this, if I reference file_picker: ^1.13.3 in pubspec.yaml, then hover automatically selects version v0.0.0-20200604215027-87ee48b7f3f6 and I'll get the exception interface conversion: interface {} is nil, not map[interface {}]interface {}. Console output:

Maybe I'm doing something wrong? I shall be fine, if you're not going to investigate this topic any further. I can build and run the Flutter app. I just need to apply this workaround where I clone your repository and reference it in pubspec.yaml. Unfortunately, I do not know enough about the interaction of Flutter, Go, and hover in combination. Otherwise, I'd help to further investigating this issue.

@miguelpruivo thank you very much for taking the effort to investigate this issue and releasing a new major version!

I updated my dependency to file_picker: ^2.0.0 and tested it on Windows 10 and on Ubuntu 19, too. On both platforms it works like a charm :+1: You might close this issue.
