QrParams class

QR parameters.

Constructors

QrParams()

Constructor

QrParams.fromJson(Map<String, dynamic> json)

Creates a QrParams instance from a JSON representation.

Properties

aspectRatio ↔ double?

Height/Width ratio of 2D BarCode module.

getter/setter pair

eCIEncoding ↔ ECIEncodings?

Extended Channel Interpretation Identifiers. It is used to tell the barcode reader details about the used references for encoding the data in the symbol. Current implementation consists all well known charset encodings.

getter/setter pair

encodeMode ↔ QREncodeMode?

QR symbology type of BarCode's encoding mode. Default value: QREncodeMode.Auto.

getter/setter pair

encodeType ↔ QREncodeType?

QR / MicroQR selector mode. Select ForceQR for standard QR symbols, Auto for MicroQR.

getter/setter pair

errorLevel ↔ QRErrorLevel?

Level of Reed-Solomon error correction for QR barcode. From low to high: LevelL, LevelM, LevelQ, LevelH. see QRErrorLevel.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

structuredAppend ↔ StructuredAppend?

QR structured append parameters.

getter/setter pair

textEncoding ↔ String?

DEPRECATED: This property is obsolete and will be removed in future releases. Unicode symbols detection and encoding will be processed in Auto mode with Extended Channel Interpretation charset designator. Using of own encodings requires manual CodeText encoding into byte[] array. Sets the encoding of codetext.

getter/setter pair

version ↔ QRVersion?

Version of QR Code. From Version1 to Version40 for QR code and from M1 to M4 for MicroQr. Default value is QRVersion.Auto.

getter/setter pair
