Selecting a single image from Google Photos does not work

[Boehrsi]

If FilePicker.getFilePath() is used and an image is added via the default file chooser + Google Photos an error occurs.

E/flutter: [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: type 'List<dynamic>' is not a subtype of type 'String'
#0 FilePicker.getFile (package:file_picker/file_picker.dart:42:18)

The reason for this problem is Google Photos and not this plugin. Even if only one file is requested Google Photos returns a list of elements, with one entry. It seems like a good idea to verify the returned data and wrap it if necessary. I will attach a PR which fixes the problem.

Thank you for your input, can you post your full log and the steps to reproduce?

[Boehrsi]

Sure :)

Device: Samsung S7 with Android 8.0.0

1. Call await FilePicker.getFilePath(type: fileType, fileExtension: extension);
2. Select Google Photos (see Screenshot, fifth from the bottom)
3. Select any image
4. See error (see trace below)

I've already fixed this in beta. Looking to deploy a version to pub dart with this and #56 fixed until the weekend.

Thank you for your feedback.

[Boehrsi]

Okay nice thank you, have a nice weekend. 👍

Fixed on 1.3.3.
