<description>
Displays OS native dialog for selecting files or directories in the file system.
Each filter string in the [param filters] array should be formatted like this: [code]*.txt,*.doc;Text Files[/code]. The description text of the filter is optional and can be omitted. See also [member FileDialog.filters].
Callbacks have the following arguments: [code]status: bool, selected_paths: PackedStringArray, selected_filter_index: int[/code].
[b]Note:[/b] This method is implemented if the display server has the [constant FEATURE_NATIVE_DIALOG_FILE] feature. Supported platforms include Linux (X11/Wayland), Windows, and macOS.
Callbacks have the following arguments: [code]status: bool, selected_paths: PackedStringArray, selected_filter_index: int[/code]. [b]On Android,[/b] callback argument [code]selected_filter_index[/code] is always zero.

[b]Note:[/b] [param current_directory] might be ignored.
[b]Note:[/b] On Linux, [param show_hidden] is ignored.
[b]Note:[/b] On macOS, native file dialogs have no title.
[b]Note:[/b] On Android, the filter strings in the [param filters] array should be specified using MIME types, for example:[code]image/png, image/jpeg"[/code]. Additionally, the [param mode] [constant FILE_DIALOG_MODE_OPEN_ANY] is not supported on Android.
[b]Note:[/b] On Android and Linux, [param show_hidden] is ignored.
[b]Note:[/b] On Android and macOS, native file dialogs have no title.
[b]Note:[/b] On macOS, sandboxed apps will save security-scoped bookmarks to retain access to the opened folders across multiple sessions. Use [method OS.get_granted_permissions] to get a list of saved bookmarks.
