Description
Nanonets provides an OCR service where we can create models, train them and use them for OCR predictions. This package is developed to make usage of Nanonets OCR api directly without having to write manual code for integrating it in your application.
Follow this blog for step by step integration of Nanonets OCR model in a Flutter application: Implementing Nanonets OCR in Flutter

Example
Fetching details using document file
import 'package:flutter_nanonets_ocr/flutter_nanonets_ocr.dart';
String apiKey = "INSERT NANONETS API KEY";
NanonetsOCR nanonetsOCR = NanonetsOCR();
FutureBuilder(
future: nanonetsOCR.predictDocumentFile(apiKey, docImage,
"INSERT OCR MODEL ID HERE", context),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.active) {
return loadingWidget();
} else if (snapshot.connectionState == ConnectionState.done) {
return yourSuccessWidget();
} else {
return loadingWidget();
}
});
Fetching details using document url
import 'package:flutter_nanonets_ocr/flutter_nanonets_ocr.dart';
String apiKey = "INSERT NANONETS API KEY";
NanonetsOCR nanonetsOCR = NanonetsOCR();
FutureBuilder(
future: nanonetsOCR.predictDocumentURL(apiKey, docImageUrl,
"INSERT OCR MODEL ID HERE", context),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.active) {
return loadingWidget();
} else if (snapshot.connectionState == ConnectionState.done) {
return yourSuccessWidget();
} else {
return loadingWidget();
}
});
