* Add code_scan_listener package * Implement wedge controller widget * Update barcode settings widget - Allow user to choose which barcode scanner to use * Fix typo * Select barcode scanner widget based on user preference * Fix rendering issues for wedge controller * Update release notes * Add unit test for wedge scanner widget - Required some tweaks to other code * Use better library - https://github.com/fuadreza/flutter_barcode_listener - Fork of https://github.com/shaxxx/flutter_barcode_listener - Properly handles key "case" issues (shift, essentially) - Verified that it works correctly for multiple character types * Local copy of code, rather than relying on package which is not available on pub.dev * Fix unit test
