seekerpay_shop 1.2.1

Product lookup, catalog, and shop utilities for SeekerPay.

Changelog

1.2.1

• Restore Scan Label button in OrderCartSheet header — taps MrpScanSheet (OCR + AI label reader) alongside the existing barcode scan button.

1.2.0

• Add tax support to Order: taxRate, country, taxUsd, taxLabel (auto-detects GST/VAT/TAX by country).
• Add inventory tracking to Product: stockLevel, lowStockThreshold, isLowStock, isOutOfStock.
• Add OrderNotifier.setTaxRate and setCountry; all mutating methods are now async with an init-completion guard.
• Add HistoryNotifier.decrementStock to reduce stock levels after a completed order.
• Add loyalty check to OrderCartSheet: scan customer wallet QR → LoyaltyNftService.customerHasLoyaltyPass → auto-apply discount. Accepts loyaltyEnabled, loyaltyDiscountPct, and merchantAddress params.
• Add ProductScanStatus.idle and ProductScanNotifier.startScanning() to prevent scans during sheet initialisation.
• Fix Irys upload: switch from signature type 4 (Solana) to type 2 (Ed25519 generic) and add uploader.irys.xyz + turbo.ardrive.io as upload endpoints.

1.1.0

• Add native SOL payment support and multi-token utilities.
• Enhance Order model and notifier with multi-token persistence.
• Synchronize with seekerpay_core 1.3.0.

1.0.5

• UI: Shop config tiles (ShopLlmSettings, ClaudeVisionSettings) — replaced yellow accent with white, transparent card backgrounds, consistent input fills and switch colors for dark purple shop mode theme.

1.0.4

• Product Catalog Arweave Sync:
  • ArweaveOrderService.saveProduct() — encrypts and uploads products to Arweave with Type=product_catalog tag.
  • ArweaveOrderService.restoreProducts() — decrypts all catalog records; deduplicates by barcode keeping the latest savedAt version.
  • ArweaveOrderService.syncProducts() — pull-only sync; merges remote products missing locally and fills in ownerPriceUsd from Arweave where local has none.
  • ArweaveOrderClient.queryProducts() — new GraphQL query targeting Type=product_catalog (refactored shared _query() helper).
  • ArweaveProductSyncResult model for product sync results.
• ownerPriceUsd priority in scanning:
  • ProductScanSheet now pre-fills price with ownerPriceUsd (merchant's set price) instead of lastPriceUsd when a local catalog match is found.
• HistoryNotifier improvements:
  • updateProduct() / saveOrder() / deleteProduct() now keep ProductCatalogService (SharedPreferences) in sync so barcode lookup always sees the latest ownerPriceUsd.
  • updateProduct() triggers an async Arweave backup immediately after save.
  • startBackgroundSync() now pulls the product catalog from Arweave alongside orders.
• Order cart:
  • Manual item entry (ADD ITEM MANUALLY button) — type name + price without scanning.
  • Order-level discount — flat $ or % discount with live preview; stored as discountUsd on Order; backward-compatible JSON.
  • setDiscount() added to OrderNotifier.
  • Dialog overflow fixed for keyboard-up state (insetPadding + SingleChildScrollView).
• Payment tolerance:
  • Overpayment auto-accepts; underpayment shows orange PARTIAL PAYMENT banner with remaining SKR; QR updates to remaining amount.

1.0.3

• Arweave/Irys Sync Fixes:
  • Corrected Ed25519 signature implementation for Solana (Irys requires hex-encoded ASCII signing of the deepHash).
  • Standardized deepHash implementation to Arweave 2.0 specs.
  • Implemented multi-node GraphQL failover (node1, node2, uploader, arweave.net).
  • Increased query timeouts to 90s and added retry logic to handle network lag.
• UI Enhancements:
  • Redesigned configuration alerts with a modern dark theme and context-aware icons.
  • Added a 'CONFIGURE' button to jump directly to shop settings.
• Dependencies:
  • Added go_router for improved navigation handling.
