4.0.0 #

  • Breaking Change: Removed QrBitBuffer from public exports to tighten the API surface.
  • Breaking Change: QrErrorCorrectLevel is now an enum (low, medium, quartile, high) instead of a class with integer constants (L, M, Q, H).
  • Breaking Change: QrCode and QrImage constructors and properties now use the QrErrorCorrectLevel enum instead of integers.
  • Breaking Change: Removed dataCache getter from QrCode.
  • Breaking Change: QrCode is now immutable. Removed addData, addByteData, addNumeric, addAlphaNumeric, and addECI from QrCode.
  • Breaking Change: Consolidated QrCode constructors into a single public factory constructor taking QrPayload, errorCorrectLevel, and an optional minTypeNumber. Removed QrCode.fromData, QrCode.fromUint8List, and QrCode.fromPayload.
  • Breaking Change: Replaced Uint8List and ByteData in public API signatures with TypedData.
  • Breaking Change: Marked all public classes (QrCode, QrImage, QrPayload, QrValidationResult, InputTooLongException) as final class to enforce structural immutability and prevent external subtyping.
  • Added QrPayload class as a standalone accumulator for multi-part data and encoding modes (Numeric, Alphanumeric, Byte, ECI). Includes constructors fromString, fromTypedData, and methods addString, addTypedData, addNumeric, addAlphaNumeric, addECI.
  • Added Extended Channel Interpretation (ECI) support via QrPayload.addECI and the QrEciValue extension type.
  • Added QrValidationResult.fromPayload factory constructor to validate QR code payloads and predict valid configurations.
  • Added QrValidationResult class returned by validation constructor.
  • QrPayload.fromString and QrPayload.addString now intelligently pick the right mode.
  • Throws InputTooLongException for data that exceeds QR code version 40 capacity, preventing the generation of invalid QR codes.
  • Performance improvements for QR code generation.
    • QrImage generation is ~50% faster.
    • LargeQrCode generation is ~40% faster.
  • Require sdk: ^3.11.0.
