Hello,

At this moment, only the bankDetails structured data extraction is exposed to the Flutter plugin but the next update will expose the other structured data: receipt and businessCard.

Which one is of interest to you?

Hi there,
The new update of the SDK v5.0.8 has been published, and it exposes the data extraction to Flutter. The documentation is updated to reflect this.

Hello @bvirlet,
that's great to hear, I will update the library and tell you the results

Hello @bvirlet
I tried the entity extraction but sadly the results were bad in a way that prevents me from using it for production

Sample 1

Image:

Scan result:

flutter: scans[0][structuredData][receipt][locale]: en-US
flutter: scans[0][structuredData][receipt][amount]: 0.0
flutter: scans[0][structuredData][receipt][category]: other
flutter: scans[0][structuredData][receipt][currency]: USD
flutter: scans[0][structuredData][receipt][date]: 1717578000.0

Issues:

• the returned amount is 0.0, original amount is 99.0
• the returned date is in invalid format (double) although I tried to convert DateTime.fromMillisecondsSinceEpoch((result['scans'][0]['structuredData']['receipt']['date'] as double).toInt()) and date returned is 1970-01-20 23:06:18.000

Sample 2

Image:

Scan result:

flutter: scans[0][structuredData][receipt][date]: 1706864400.0
flutter: scans[0][structuredData][receipt][currency]: USD
flutter: scans[0][structuredData][receipt][category]: supermarket
flutter: scans[0][structuredData][receipt][merchant]: nd February
flutter: scans[0][structuredData][receipt][locale]: en-US
flutter: scans[0][structuredData][receipt][amount]: 23.9

Issues:

• the returned date is same as issue in Sample 1
• the returned category is wrong, I can't find the word "supermarket" mentioned in the image so I don't know where did it come from, NOTE: I don't use the category but it's still an issue for other users maybe
• the returned merchant is also wrong, I don't know why it took "nd February" as a merchant name, it's not bold neither headline text, what are the factors the determine this is a merchant name?
