Hi,

getting below error when i try to install the package in expo existing project.

react-native-document-scanner-plugin - 2.0.2

Please suggest fix or workaround

[dmarcs]

Try npm install react-native-document-scanner-plugin@1.0.1

You're probably working on an older project that doesn't have TurboModules. If you install an older version of this plugin 1.01 it should work.

@dmarcs tried version 1.0.1.

with 1.0.1, I am getting different error.

I did rebuild and using expo. still getting this error.

[dmarcs]

Are you using Expo Go? I would create a new project, install the plugin (you can use the latest version if you're using TurboModules), and see if you still get an error.

I'm using react-native: 0.76, and 2.0.3 for react-native-document-scanner-plugin, still getting the same error.
TurboModules are bydefault on, what could be the quick workaround?

Replace code node_modules/react-native-document-scanner-plugin/ios/DocumentScanner.mm with below

#import <VisionKit/VisionKit.h>
#import "DocumentScanner.h"
#import <React/RCTBridgeModule.h>
#import <React/RCTUtils.h>

#if __has_include(<DocumentScanner/DocumentScanner-Swift.h>)
#import <DocumentScanner/DocumentScanner-Swift.h>
#elif __has_include("DocumentScanner-Swift.h")
#import "DocumentScanner-Swift.h"
#else
#warning "DocumentScanner-Swift.h not found at build time"
#endif

@implementation DocumentScanner

// Explicitly register the module
RCT_EXPORT_MODULE(DocumentScanner)

// Classic bridge method (NO TurboModules, NO codegen)
RCT_EXPORT_METHOD(scanDocument:(NSDictionary *)options
resolve:(RCTPromiseResolveBlock)resolve
reject:(RCTPromiseRejectBlock)reject)
{
if (@available(iOS 13.0, *)) {
RNDocumentScanner *documentScanner = [RNDocumentScanner new];
[documentScanner scanDocument:options resolve:resolve reject:reject];
} else {
reject(
@"UNSUPPORTED_IOS_VERSION",
@"Document scanning requires iOS 13 or later",
nil
);
}
}
