I need to open a native system specific folder similar to the image below with Flutter desktop:

FilePicker package doesn't work as it opens a "random" folder and I need it to be a specific folder

This is a Mac OS example, but I need it to open on Windows and Linux as well.

CodePudding user response：

you can use package

This package work on all platform marked

Single file

FilePickerResult? result = await FilePicker.platform.pickFiles();

if (result != null) {
  File file = File(result.files.single.path);
} else {
  // User canceled the picker
}

Multiple files

FilePickerResult? result = await FilePicker.platform.pickFiles(allowMultiple: true);

if (result != null) {
  List<File> files = result.paths.map((path) => File(path)).toList();
} else {
  // User canceled the picker
}

In Windows Like this:
