Constructors

EasyQRImage({Key? key, required String data, int size = 10, Color? color = Colors.black, Color? backgroundColor = Colors.white, int? margin = 1, int? quietZone = 0, Formats? format, Charsets? charsetTarget, Charsets? charsetSource, Ecc? ECC})

Properties

backgroundColor → Color?
Color of the background
final
charsetSource → Charsets?
Specifies the charset to encode the text submitted via data parameter with, before storing it within the QR code. Note: you don't have to care about converting your data if charset-source and charset-target got different values, the API does all the needed work automatically.
final
charsetTarget → Charsets?
Specifies the charset the text submitted via data parameter is encoded in. Note: you don't have to care about converting your data if charset-source and charset-target got different values, the API does all the needed work automatically.
final
color → Color?
Color of the data modules
final
data → String
The text to store within the QR code.
final
ECC → Ecc?
Defines the error correction code (ECC) which determines the degree of data redundancy. The more data redundancy exists, the more data can be restored if a QR code is damaged (i.e. scratches on a QR code sticker or something like that).
final
format → Formats?
It is possible to create the QR code picture using different file formats, available are PNG, GIF, JPEG and the vector graphic formats SVG and EPS (=you can create QR code vector graphics / QR code EPS / QR code SVG as needed for professional printing).
final
getCharsetsSource → String
no setter
getCharsetsTarget → String
no setter
getECC → String
no setter
getFormats → String
no setter
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
margin → int?
Thickness of a margin in pixels. The margin will always have the same color as the background.
final
quietZone → int?
Thickness of a margin (=“quiet zone”, an area without disturbing elements to help readers locating the QR code), in modules as measuring unit.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
size → int
Specifies the size of the QR code image you want to generate (in px for raster graphic formats like png, gif or jpeg); as logical unit for vector graphics (svg, eps).
final
