Installing #

You can install the package by adding the following lines to your pubspec.yaml:

dependencies:
  qr_flutter: ^1.1.0

After adding the dependency to your pubspec.yaml you can run: pub get or flutter packages get if you're using Flutter.

To start, import the dependency in your code:

import 'package:qr_flutter/qr_flutter.dart';

Next, to render a basic QR code you can do as such:

new QrImage(
  data: "1234567890",
  size: 200.0,
),

Depending on your data requirements you may want to tweak the QR code output:

`size`	double	The (square) size of the image
`padding`	EdgeInsets	Padding surrounding the QR code data
`backgroundColor`	Color	The background color (default is none)
`foregroundColor`	Color	The foreground color (default is black)

See the example directory for a basic working example.
