kasseneck_api 3.2.0

A Flutter package for interacting with the Kasseneck Cashregister API. By Kreiseck.

3.2.0

• Kreiseck branding on receipts: when the backend metadata flag kreiseck_logo is set (Firestore users/{uid}.branding.kreiseck_logo), the receipt ends with "powered by" and the Kreiseck logo — on thermal prints (85 % paper width), in KeckReceiptWidget and survives JSON round-trips for reprints
• The logo ships as a package asset (printing works offline; the backend only sends the flag); branding can never break receipt printing
• Fixed an ESC/POS rasterizer crash for images whose width is not a multiple of 8

3.1.1

• Zero analyzer issues: debug-only logging, migrated deprecated APIs (License.nonprofit, QR eyeStyle/dataModuleStyle), removed redundant imports; FinanzOnline status enum names are intentionally kept verbatim (they must match the rkdbMessage values)
• CI runs flutter analyze in strict mode again

3.1.0

• Comprehensive test suite (~100 new tests): money & receipt math, JSON round-trips and fallback parsing, voucher rules, mocked API client, and a print↔widget consistency check that guards the two independent VAT-table renderers against drift
• KasseneckApi and LogoService accept an injectable http.Client (useful for testing/mocking; default behaviour unchanged)
• financeWebService requests now also time out after 30 s
• Continuous integration: analyze + tests run on every push

3.0.1

• getReceipts no longer fails wholesale when a single receipt can't be parsed — broken receipts are skipped (and logged in debug builds)
• Zero receipts (no items) parse correctly; item quantities also accept 1.0
• All HTTP requests time out after 30 s instead of hanging silently forever
• Odd voucher amounts are displayed exactly (e.g. € 1,50 instead of ~2)

3.0.0

Breaking: money is now integer cents — exact arithmetic, no floating-point drift. No backend update is required: requests carry BOTH representations (priceOne/value in euro for the current backend and priceOneCents/valueCents/singlePriceCents, preferred by newer backends). When reading, the cents fields are preferred; euro-only data (old receipts) still parses — the euro↔cents round-trip is lossless (verified by property tests).

Migration:

• KasseneckItem(singlePrice: 19.99) → KasseneckItem(priceCents: 1999) or KasseneckItem.euro(singlePrice: 19.99)
• KeckVoucher(value: 5.0) → KeckVoucher(valueCents: 500) or KeckVoucher.euro(value: 5.0)
• KeckInvoiceItem(singlePrice: …) → priceCents / KeckInvoiceItem.euro(…)
• Reading: item.singlePrice, voucher.value, receipt.sum / subSum still exist as euro views; for arithmetic use priceCents / valueCents / sumCents / subSumCents / totalCents
• Terminal APIs (hobexPay, HpsClient, SumUp) keep euro amounts — they mirror the external providers' formats

2.1.3

• Reliable Bluetooth thermal printing: flow control via write-with-response (backpressure), negotiated MTU with matching chunk size, and pacing for write-without-response printers
• Fixed garbled QR output: the QR image is now composited onto a white background with a quiet zone (QrPainter renders on transparent, which ESC/POS rasterization printed as solid black)
• New QrPrintMode (imageRaster / imageBitImage / native) on printReceiptBluetooth / getPrintBytes to pick the command your printer supports (replaces qrAsImage)

2.1.2

• Cleaner static analysis (0 warnings): KeckVoucher.value is now nullable; removed dead null-aware code and unused SumUp leftovers
• Loosened the my_pos version constraint to ^0.3.0

2.1.1

• New README, a runnable example/ and inline API documentation (dartdoc)
• Added repository & issue tracker metadata

2.1.0

• hobex Payment Service (HPS): lokaler Terminal-Client (HpsClient) mit Zahlung, Pre-Auth, Capture, Refund, Storno, Status, Abbruch, AVT und Diagnose
• HobexReceipt.fromHps + Karten-Beleg-Rendering (Provider hobexHps); HobexReceipt aus dem hobex_hps-Barrel exportiert

2.0.0

• image plugin update
• voucher logic implemented

1.1.0

• Added new endpoints

1.0.0

• Initial release of kasseneck_api
