• Minor bugs

0.4.5

Fixed

• Minor bugs

0.4.4

Added

• Circle Payments integration — Headless card-to-USDC payment flow using Circle Payments API with client-side RSA-OAEP encryption (PCI compliant).
• CircleService — Fetches Circle encryption key, encrypts card data locally, submits payment, and polls for confirmation.
• CircleCardForm widget — Native card entry form with input validation, client-side encryption, and payment processing.
• CardProvider.circle enum value for gateway card provider selection.
• circlePaymentId field on PayRogenCheckoutResult.

Changed

• Updated flutter_secure_storage to ^11.0.0 for latest platform support.
• Updated flutter_lints to ^6.0.0 for latest analysis rules.
• Added pointycastle and uuid dependencies for Circle card encryption.

0.4.2

Fixed

• Fixed "UNKNOWN PLATFORMS" on pub.dev by correcting pubspec platform declaration format.

0.4.1

Fixed

• Removed explicit platforms declaration that caused pub.dev to report "UNKNOWN PLATFORMS". Platform support is now auto-detected from dependencies (Android, iOS, Web, macOS, Windows, Linux).

0.4.0

Changed

• QR code and wallet buttons now route through the smart contract — uses Solana Pay Transaction Request format pointing to the gateway's /solana-tx endpoint which builds the execute_split_payment program instruction. All payments enforce on-chain splits and gateway fee deduction.
• Wallet deep links (Phantom/Solflare) pass the transaction request URL so the wallet builds the correct smart contract call.

0.3.9

Fixed

• Critical: Payment no longer marked as successful without on-chain confirmation. SDK now polls the gateway's /pay/:code/status endpoint and only shows success when the transaction is verified on-chain.
• Changed header/button gradient to PayRogen blue/purple brand colors.
• Removed raw wallet address display from crypto payment screen.

0.3.8

Fixed

• Connect Phantom no longer shows instant success — SDK now polls for on-chain confirmation (up to 2 min) after wallet is launched. Success only shown when transaction is verified.
• Connect Solflare fixed — uses correct Solflare universal link (solflare.com/ul/v1/pay).
• Removed raw wallet address display — payments go through the smart contract via Solana Pay transaction request, not direct transfers.
• QR code now encodes Solana Pay transaction request URL pointing to the gateway's /solana-tx endpoint (ensures splits, fees, and escrow are enforced on-chain).

0.3.7

Changed

• Crypto payment screen redesigned to match the web checkout:
  • Added "Connect Solflare" and "Connect Phantom" buttons with deep linking
  • Added Solana Pay compatible QR code
  • Removed manual "I've Sent the Payment" button — payment detection now uses polling after wallet launch
  • Wallet address shown compactly with copy button

Added

• qr_flutter dependency for QR code generation
• url_launcher dependency for wallet deep linking
• Auto-payment polling after wallet app is launched

0.3.6

Fixed

• Wallet.fromJson no longer crashes with type 'Null' is not a subtype of type 'String' when gateway returns null fields. All fields now have safe null fallbacks.

0.3.5

Fixed

• Resolved all deprecated API usages (withOpacity → withValues, Color.blue → modern API).
• Fixed lint info: use null-aware operator.
• Static analysis now reports zero issues (targeting 160/160 pub points).

0.3.4

Added

• exportPrivateKey(userId) — Allows wallet owners to export their private key for use in external wallets (Phantom, Solflare, etc.).
• Marketplace Integration guide in README.

Fixed

• Critical: All API endpoints now use the correct /api/v1/ prefix. Previously the SDK was calling /v1/... which returned 404 from the gateway.

0.3.3

Changed

• Updated all split examples to reflect 1.5% platform fee (was incorrectly showing 10-15%).

0.3.2

Changed

• Updated README: clarified non-custodial wallet description.

0.3.1

Changed

• Updated README documentation.

0.3.0

Added

• Drop-in Checkout UI — payrogen.checkout() single method that shows the full payment sheet with zero custom UI code required.
• Escrow Mode — Pass escrow: true to checkout() to create escrow payments with auto-release timeout.
• releaseEscrow() — Release funds after delivery confirmation.
• disputeEscrow() — Dispute an escrow payment with a reason.
• Theme-aware UI — Checkout sheet automatically adapts to your app's light/dark theme.
• Custom accent color — Optional accentColor parameter for brand customization.
• PayRogenCheckoutResult — Rich result object with success, cancelled, signature, escrowId, walletAddress, amount, currency, and metadata.
• Split payments — Pass splits map to checkout() for automatic on-chain fee splitting.
• Metadata — Attach arbitrary metadata (order IDs, user IDs) to transactions.
• Success animation — Built-in success screen after payment confirmation.

Changed

• Bumped minimum version to 0.3.0.
• CheckoutResult is now a type alias for PayRogenCheckoutResult (backward compatible).
• PaymentCheckoutSheet UI completely redesigned with gradient header, card-based method selection, and polished animations.

0.2.0

• Initial release with wallet creation, direct payments, escrow, recovery, and basic checkout widget.
• Multi-chain wallet support (Solana, EVM, Bitcoin).
• External wallet management with cooldown periods.
• Withdrawal with fee estimation.
• Network mismatch pre-flight validation.
