Scanner Flow

DocumentScannerFlow provides a route-driven scan experience:

• scan: capture photo with live contour overlay.
• edit: adjust crop points and apply filter previews.
• share: preview processed output and share it.
• ocr: run OCR on processed image.

Default usage

import { DocumentScannerFlow } from '@korsolutions/vision';

export function ScannerScreen() {
  return <DocumentScannerFlow initialRoute="scan" />;
}

Navigation model

The flow uses an internal route stack and a navigation manager exported as:

• ScannerNavigationProvider
• useScannerNavigation
• ScannerRoute

Route reset behavior:

• Navigating to scan resets the stack to ['scan'].

Session state model

Session state is managed in ScannerProvider and exposed via useScannerContext.

Key state values:

• capturedImage
• cropPoints
• selectedFilter
• editPreviewUri
• processedImageUri
• isFilterProcessing
• isFinalizing
• processingError

Key actions:

• startSession(...)
• setCropPoints(...)
• setSelectedFilter(...)
• finalizeDocument()
• resetSession()
