GeneratedBindings class

Bindings for src/native_zxing.h.

Regenerate bindings with flutter pub run ffigen --config ffigen.yaml.

Constructors

GeneratedBindings.new(DynamicLibrary dynamicLibrary)

The symbols are looked up in dynamicLibrary.

GeneratedBindings.fromLookup(Pointer<T> lookup<T extends NativeType>(String symbolName))

The symbols are looked up with lookup.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

encodeBarcode(Pointer<Char> contents, int width, int height, int format, int margin, int eccLevel) → EncodeResult

@brief Encode a string into a barcode @param contents The string to encode. Owned pointer. Will be freed by native code. @param width The width of the barcode in pixels. @param height The height of the barcode in pixels. @param format The format of the barcode @param margin The margin of the barcode @param eccLevel The error correction level of the barcode. Used for Aztec, PDF417, and QRCode only, 0-8. @return The barcode data.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

readBarcode(Pointer<Uint8> bytes, int imageFormat, int format, int width, int height, int cropWidth, int cropHeight, bool tryHarder, bool tryRotate, bool tryInvert) → CodeResult

@brief Read barcode from image bytes. @param bytes Image bytes. Owned pointer. Will be freed by native code. @param imageFormat Image format. @param format Specify a set of BarcodeFormats that should be searched for. @param width Image width in pixels. @param height Image height in pixels. @param cropWidth Crop width. @param cropHeight Crop height. @param tryHarder Spend more time to try to find a barcode; optimize for accuracy, not speed. @param tryRotate Also try detecting code in 90, 180 and 270 degree rotated images. @return The barcode result.

readBarcodes(Pointer<Uint8> bytes, int imageFormat, int format, int width, int height, int cropWidth, int cropHeight, bool tryHarder, bool tryRotate, bool tryInvert) → CodeResults

@brief Read barcodes from image bytes. @param bytes Image bytes. Owned pointer. Will be freed by native code. @param imageFormat Image format. @param format Specify a set of BarcodeFormats that should be searched for. @param width Image width in pixels. @param height Image height in pixels. @param cropWidth Crop width. @param cropHeight Crop height. @param tryHarder Spend more time to try to find a barcode, optimize for accuracy, not speed. @param tryRotate Also try detecting code in 90, 180 and 270 degree rotated images. @return The barcode results.

setLogEnabled(bool enabled) → void

@brief Enables or disables the logging of the library.

toString() → String

A string representation of this object.

inherited

version() → Pointer<Char>

Returns the version of the zxing-cpp library. Pointer has a static lifetime and must not be freed.

Operators

operator ==(Object other) → bool

The equality operator.
