qr_image_exporter 2.0.0

An extension for the `qr.dart` package that provides a simple and robust way to export QR code modules as customizable PNG byte data.

2.0.0

This release upgrades the qr dependency to 4.0.0, which contains breaking API changes. Because this package's extension is defined on QrImage, users must construct QrImage using the qr package directly — making qr's API an inseparable part of the user-facing interface. Upgrading to this version therefore requires updating call sites accordingly.

Breaking Changes

• Raised minimum qr constraint to ^4.0.0. qr 4.0.0 renamed and restructured several APIs. The following changes are required in your code when upgrading:
  • QrCode.fromData(data: ..., errorCorrectLevel: ...) → QrCode(payload: QrPayload.fromString(...), errorCorrectLevel: ...)
  • QrErrorCorrectLevel.L → QrErrorCorrectLevel.low
  • QrErrorCorrectLevel.M → QrErrorCorrectLevel.medium
  • QrErrorCorrectLevel.Q → QrErrorCorrectLevel.quartile
  • QrErrorCorrectLevel.H → QrErrorCorrectLevel.high
• Raised minimum Dart SDK constraint to ^3.11.0 (previously ^3.8.1), as required by qr 4.0.0. Dart 3.8.x–3.10.x are no longer supported.

1.0.1

• Fixed: Prevent Out-Of-Memory (OOM) crashes by validating maximum safe hardware texture limits.
• Fixed: Add validation for invalid parameters to prevent errors when moduleSize or margin are negative.
• Fixed: Update toPngBytes doc comments to accurately reflect the internal error handling behavior.
• Added: Introduce GitHub Actions CI workflow for automated testing and static analysis on Dart SDK 3.8.1 and stable.
• Changed: Remove the unused lints dev dependency to clean up project dependencies.

1.0.0

• Initial stable release.
• Provides the QrImageExporter extension on QrImage to export QR codes as PNG byte data.
• Adds the toPngBytes method with customizable parameters for moduleSize, margin, darkColor, and lightColor.
• Depends on the image package to handle image creation and PNG encoding.
