Printing

Plugin that allows Flutter apps to generate and print documents to android or ios compatible printers

See the example on how to use the plugin.

This plugin uses the pdf package https://pub.dartlang.org/packages/pdf for pdf creation. Please refer to https://pub.dartlang.org/documentation/pdf/latest/ for documentation.

To load an image it is possible to use Image.toByteData:

var Image im;
var bytes = await im.toByteData(format: ui.ImageByteFormat.rawRgba);

PdfImage image = PdfImage(
    pdf,
    image: bytes.buffer.asUint8List(), 
    width: im.width, 
    height: im.height);
g.drawImage(image, 100.0, 100.0, 80.0);

To use a TrueType font from a flutter bundle:

var font = await rootBundle.load("assets/open-sans.ttf");
PdfTtfFont ttf = PdfTtfFont(pdf, font);
g.setColor(PdfColor(0.3, 0.3, 0.3));
g.drawString(ttf, 20.0, "Dart is awesome", 50.0, 30.0);
