How to convert Flutter SfCalendar to PDF using PDF Viewer?
In the Flutter SfCalendar feature tour page, you can convert the SfCalendar into a PDF document by using the PDF Viewer control.
STEP 1: Add the required packages in Pubspec.yaml file.
dependencies: syncfusion_flutter_pdf: ^19.2.47-beta syncfusion_flutter_calendar: ^19.2.47 path_provider: ^2.0.2 open_file: ^3.2.1 flutter: sdk: flutter
STEP 2: Add the following methods for converting the calendar to PDF.
Future<void> _renderCalendarPDF() async {
PdfDocument document = PdfDocument();
PdfPage page = document.pages.add();
final RenderRepaintBoundary boundary =
_globalKey.currentContext?.findRenderObject() as RenderRepaintBoundary;
final ui.Image data = await boundary.toImage(pixelRatio: 3.0);
final ByteData? bytes =
await data.toByteData(format: ui.ImageByteFormat.png);
final Uint8List imageBytes =
bytes!.buffer.asUint8List(bytes.offsetInBytes, bytes.lengthInBytes);
page.graphics
.drawImage(PdfBitmap(imageBytes), Rect.fromLTWH(25, 50, 300, 300));
List<int> byteData = document.save();
document.dispose();
Directory? directory = await getExternalStorageDirectory();
String path = directory!.path;
print(path.toString() + ' Path');
File file = File('$path/Output.pdf');
await file.writeAsBytes(byteData, flush: true);
OpenFile.open('$path/Output.pdf');
}
STEP 3: Call this method using onPressed() callback of the button.
body: Column(
children: [
Container(
height: 400,
width: 400,
child: RepaintBoundary(
key: _globalKey,
child: SafeArea(child: SfCalendar()),
),
),
Padding(
padding: const EdgeInsets.only(top: 10.0),
child: ElevatedButton(
onPressed: _renderCalenPDF, child: Text('Calendar to pdf'),),
),
],
),
