Flutter Barcode Scanner (flutter_barcode_scanner: ^2.0.0)

Building the Flutter 💙 Barcode Scanner app

My project needs to be able to scan an inventory of items with barcodes and save them to a database. Optionally it could look up the description of the item from a source database or service. Then it needs to make that inventory available for use by other services such as a web site. This seems like something Flutter, and Firebase ought to be able to do.

You can find and use packages to build Dart and Flutter apps at pub.dev which is where flutter_barcode_scanner: ^2.0.0 is to be found.

TL:DR — It 'just works' with Flutter 2.x so it will be good for the project.

It built and runs just fine on my Pixel 2XL. On first scan it asks for camera permission, and then presents a simple scanning UI with a barcode overlay on the camera. As soon as the barcode on my soup can came into view it recorded the scan result on the page and output it to the Android Studio console. Looks very professional. Works and works quickly. Excellent.
