defaultMargin → int: no setter
hashCode → int: The hash code for this object.

runtimeType → Type: A representation of the runtime type of the object.

supportedWriteFormats → List<BarcodeFormat>?: no setter

encode(String contents, BarcodeFormat format, int width, int height, [Map<EncodeHintType, Object>? hints]) → BitMatrix: Encode the contents following specified format. width and height are required size. This method may return bigger size BitMatrix when specified size is too small. The user can set both width and height to zero to get minimum size barcode. If negative value is set to width or height, IllegalArgumentException is thrown.
override
encodeContent(String contents, [Map<EncodeHintType, Object?>? hints]) → List<bool>: Encode the contents to bool array expression of one-dimensional barcode. Start code and end code should be included in result, and side margins should not be included.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toString() → String: A string representation of this object.

appendPattern(List<bool> target, int pos, List<int> pattern, bool startColor) → int: @param target encode black/white pattern into this array @param pos position to start encoding at in target @param pattern lengths of black/white runs to encode @param startColor starting color - false for white, true for black @return the number of elements added to target.
checkNumeric(String contents) → void: @param contents string to check for numeric characters @throws IllegalArgumentException if input contains characters other than digits 0-9.
