MultiFormatReader class

MultiFormatReader is a convenience class and the main entry point into the library for most uses. By default it attempts to decode all barcode formats that the library supports. Optionally, you can provide a hints object to request different behavior, for example only decoding QR codes.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

Methods

decode(BinaryBitmap image, [Map<DecodeHintType, Object>? hints]) → Result

Decode an image using the hints provided. Does not honor existing state.

override

decodeWithState(BinaryBitmap image) → Result

Decode an image using the state set up by calling setHints() previously. Continuous scan clients will get a large speed increase by using this instead of decode().

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → void

Resets any internal state the implementation has after a decode, to prepare it for reuse.

override

setHints(Map<DecodeHintType, Object>? hints) → void

This method adds state to the MultiFormatReader. By setting the hints once, subsequent calls to decodeWithState(image) can reuse the same set of readers without reallocating memory. This is important for performance in continuous scan clients.

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
