Flutter Flutter Barcodes

Overview

The Flutter Barcode Generator widget is a data visualization widget that is used to generate and display data in the machine-readable, industry-standard 1D and 2D barcodes. It provides a perfect approach to encode input values using supported symbology types.

Human-readable text

The Flutter Barcode Generator lets you display a barcode with or without input value text, along with alignment options. Also, customize the style of the text.

Barcode symbologies

Flutter Barcode Generator widget supports a wide range of barcode symbologies.

QR barcode.

QR Code

Quick response code (QR code) is a two-dimensional barcode. It can efficiently store more information in a smaller space than 1D barcodes. Each barcode can store values up to 7089 characters. It is mostly used for URLs, business cards, contact information, etc.

Data matrix barcode.

Data Matrix

A Data Matrix is two-dimensional barcode. The information can be encoded with text or numeric values. Each barcode can store values up to 2335 characters. Data Matrix barcode will be mostly used for courier parcel, food industry, etc.

Code 128 barcode.

Code 128

Code 128 is a very high-density barcode that supports alphanumeric characters. This barcode is used as the basis for many other barcodes like UCC/EAN, HIBC (health industry barcodes), and the Blood Bank industry.

UPC-A barcode.

UPC-A

The universal product code (UPC -A) is a numeric symbology used in worldwide retail applications. UPC-A symbols consist of 11 data digits and one check digit. The first digit is a number system digit that normally represents the type of product being identified.

UPC-E barcode.

UPC-E

As with UPC-A, the UPC-E symbology supports only numeric characters. It is a zero-suppressed version of UPC-A symbology where it uses only 6 digits of product code and does not use the middle guard.

EAN-13 barcode.

EAN-13

EAN-13 is based on the UPC-A standard. As with UPC-A, it supports only numeric characters. It encodes the 12 digits of input data with the check digit at its end. The difference between UPC-A and EAN-13 is that the number system used in EAN-13 is in two-digit ranges from 00 to 99, whereas the number system used in UPC-A is in single digits from 0 to 9.

EAN-8 barcode.

EAN-8

EAN-8 is equivalent to the UPC-E for small packaging details. It is shorter than the EAN-13 barcode and longer than UPC-E. It encodes 7 digits of numeric data with the check digit at its end.

Code 39 barcode.

Code 39

Code 39 is a common barcode type used for various labels such as name badges, inventory, and industrial applications. The symbology of the Code 39-character set consists of barcode symbols representing numbers 0-9, uppercase letters A-Z, and the space character.

Code 39 Extended barcode.

Code 39 Extended

The Code 39 Extended is an extended version of Code 39. Lower characters and special characters are additionally supported.

Code 93 barcode.

Code 93

Code 93 was designed to complement and improve Code 39. It is used to represent the full ASCII character set by using combinations of two characters. Code 93 can encode uppercase letters, numeric digits, and a handful of special characters.

Codabar barcode.

Codabar

Codabar is a discrete numeric symbology that is used in libraries, blood banks, and a variety of other information processing applications. It can encode 0-9 digits, six symbols, and start and stop characters.
