Constructors

CodeType()

Abstract constructor

const

CodeType.fromType(CodeGenerateType type)

Create a specific CodeType instance based on the CodeGenerateType this uses only the default barcode settings. For finer-grained usage, use the static methods:

factory

Properties

charSet → Iterable<int>

Returns the list of accepted codePoints for this CodeType

no setter

hashCode → int

The hash code for this object.

no setter, inherited

maxLength → int

Returns maximum number of characters this CodeType can encode

no setter

minLength → int

Returns minimum number of characters this CodeType can encode

no setter

name → String

Returns the name of this CodeType

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

isValid(String data) → bool

Check if the Barcode is valid

isValidBytes(Uint8List data) → bool

Check if the Barcode is valid

make(String data, {required double width, required double height, bool drawText = false, double? fontHeight, double? textPadding}) → Iterable<BarcodeElement>

Main method to produce the barcode graphic description. Returns a stream of drawing operations required to properly display the barcode as a UTF-8 string.

makeBytes(Uint8List data, {required double width, required double height, bool drawText = false, double? fontHeight, double? textPadding}) → Iterable<BarcodeElement>

Generate the barcode graphic description like make but takes a Uint8List data.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

toSvg(String data, {double x = 0, double y = 0, double width = 200, double height = 80, bool drawText = true, String fontFamily = 'monospace', double? fontHeight, double? textPadding, int color = 0x000000, bool fullSvg = true, double baseline = .75}) → String

Create an SVG file with this Barcode from String data

toSvgBytes(Uint8List data, {double x = 0, double y = 0, double width = 200, double height = 80, bool drawText = true, String fontFamily = 'monospace', double? fontHeight, double? textPadding, int color = 0x000000, bool fullSvg = true, double baseline = .75}) → String

Create an SVG file with this Barcode from Uint8List data

verify(String data) → void

Check if the Barcode is valid. Throws BarcodeException with a proper message in case of error

verifyBytes(Uint8List data) → void

Check if the Barcode is valid. Throws BarcodeException with a proper message in case of error

Operators

operator ==(Object other) → bool

The equality operator.
