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-web.flutter-io.cn/packages/pdf
for pdf creation. Please refer to https://pub-web.flutter-io.cn/documentation/pdf/latest/
for documentation.
Example:
final pdf = Document();
pdf.addPage(Page(
pageFormat: PdfPageFormat.a4,
build: (Context context) {
return Center(
child: Text("Hello World"),
); // Center
})); // Page
To load an image from an ImageProvider:
const imageProvider = const AssetImage('assets/image.png');
final PdfImage image = await pdfImageFromImageProvider(pdf: pdf.document, image: imageProvider);
pdf.addPage(Page(
build: (Context context) {
return Center(
child: Image(image),
); // Center
})); // Page
To use a TrueType font from a flutter bundle:
final font = await rootBundle.load("assets/open-sans.ttf");
final ttf = Font.ttf(font);
pdf.addPage(Page(
build: (Context context) {
return Center(
child: Text('Dart is awesome', style: TextStyle(font: ttf, fontSize: 40)),
); // Center
})); // Page
To save the pdf file using the path_provider library:
final output = await getTemporaryDirectory();
final file = File("${output.path}/example.pdf");
await file.writeAsBytes(pdf.save());
You can also print the document using the iOS or Android print service:
await Printing.layoutPdf(
onLayout: (PdfPageFormat format) async => pdf.save());
Or share the document to other applications:
await Printing.sharePdf(bytes: pdf.save(), filename: 'my-document.pdf');
To print an HTML document, simply do:
await Printing.layoutPdf(
onLayout: (PdfPageFormat format) async => await Printing.convertHtml(
format: format,
html: '<html><body><p>Hello!</p></body></html>',
));
