Getting started

Import the following package to your project to create a PDF document from scratch.

import 'package:syncfusion_flutter_pdf/pdf.dart';

Create a PDF document from simple text

Add the following code to create a simple PDF document.

// Create a new PDF document.
final PdfDocument document = PdfDocument();
// Add a PDF page and draw text.
document.pages.add().graphics.drawString(
    'Hello World!', PdfStandardFont(PdfFontFamily.helvetica, 12),
    brush: PdfSolidBrush(PdfColor(0, 0, 0)),
    bounds: const Rect.fromLTWH(0, 0, 150, 20));
// Save the document.
File('HelloWorld.pdf').writeAsBytes(document.save());
// Dispose the document.
document.dispose();

Add text using TrueType fonts

Use the following code to add a Unicode text to the PDF document.

//Create a new PDF document
final PdfDocument document = PdfDocument();
//Read font data
final Uint8List fontData = File('arial.ttf').readAsBytesSync();
//Create a PDF true type font object
final PdfFont font = PdfTrueTypeFont(fontData, 12);
//Draw text using ttf font
document.pages.add().graphics.drawString('Hello World!!!', font,
    bounds: const Rect.fromLTWH(0, 0, 200, 50));
// Save the document
File('TrueType.pdf').writeAsBytes(document.save());
// Dispose the document
document.dispose();

Add images to a PDF document

PdfBitmap class is used to draw images to a PDF document. Now, Syncfusion Flutter PDF supports only PNG and JPEG images. Refer to the following code to draw images to a PDF document.

//Create a new PDF document
final PdfDocument document = PdfDocument();
//Read image data
final Uint8List imageData = File('input.png').readAsBytesSync();
//Load the image using PdfBitmap
final PdfBitmap image = PdfBitmap(imageData);
//Draw the image to the PDF page
document.pages
    .add()
    .graphics
    .drawImage(image, const Rect.fromLTWH(0, 0, 500, 200));
// Save the document
File('ImageToPDF.pdf').writeAsBytes(document.save());
// Dispose the document
document.dispose();

PDF document with flow layout

Add the following code to create a PDF document with flow layout.

const String paragraphText =
    'Adobe Systems Incorporated\'s Portable Document Format (PDF) is the de facto'
    'standard for the accurate, reliable, and platform-independent representation of a paged'
    'document. It\'s the only universally accepted file format that allows pixel-perfect layouts.'
    'In addition, PDF supports user interaction and collaborative workflows that are not'
    'possible with printed documents.';

// Create a new PDF document
final PdfDocument document = PdfDocument();
// Add a new page to the document
final PdfPage page = document.pages.add();
// Create a new PDF text element class and draw the flow layout text
final PdfLayoutResult layoutResult = PdfTextElement(
        text: paragraphText,
        font: PdfStandardFont(PdfFontFamily.helvetica, 12),
        brush: PdfSolidBrush(PdfColor(0, 0, 0)))
    .draw(
        page: page,
        bounds: Rect.fromLTWH(
            0, 0, page.getClientSize().width, page.getClientSize().height),
        format: PdfLayoutFormat(layoutType: PdfLayoutType.paginate));
// Draw the next paragraph/content
page.graphics.drawLine(
    PdfPen(PdfColor(255, 0, 0)),
    Offset(0, layoutResult.bounds.bottom + 10),
    Offset(page.getClientSize().width, layoutResult.bounds.bottom + 10));
// Save the document
File('TextFlow.pdf').writeAsBytes(document.save());
// Dispose the document
document.dispose();

Add bullets and lists

Add the following code to create bullets and lists in a PDF document.

// Create a new PDF document
final PdfDocument document = PdfDocument();
// Add a new page to the document
final PdfPage page = document.pages.add();
// Create a PDF ordered list
final PdfOrderedList orderedList = PdfOrderedList(
    items: PdfListItemCollection(<String>[
      'Mammals',
      'Reptiles',
      'Birds',
      'Insects',
      'Aquatic Animals'
    ]),
    marker: PdfOrderedMarker(
        style: PdfNumberStyle.numeric,
        font: PdfStandardFont(PdfFontFamily.helvetica, 12)),
    markerHierarchy: true,
    format: PdfStringFormat(lineSpacing: 10),
    textIndent: 10);
// Create a un ordered list and add it as a sublist.
orderedList.items[0].subList = PdfUnorderedList(
    marker: PdfUnorderedMarker(
        font: PdfStandardFont(PdfFontFamily.helvetica, 10),
        style: PdfUnorderedMarkerStyle.disk),
    items: PdfListItemCollection(<String>[
      'body covered by hair or fur',
      'warm-blooded',
      'have a backbone',
      'produce milk',
      'Examples'
    ]),
    textIndent: 10,
    indent: 20);
// Draw the list to the PDF page
orderedList.draw(
    page: page,
    bounds: Rect.fromLTWH(
        0, 0, page.getClientSize().width, page.getClientSize().height));
// Save the document
File('BulletandList.pdf').writeAsBytes(document.save());
// Dispose the document
document.dispose();

Add tables

Add the following code to create a PDF table.

// Create a new PDF document
final PdfDocument document = PdfDocument();
// Add a new page to the document

// Specify the grid columns count
grid.columns.add(count: 3);
// Add a grid header row
final PdfGridRow headerRow = grid.headers.add(1)[0];
headerRow.cells[0].value = 'Customer ID';
headerRow.cells[1].value = 'Contact Name';
headerRow.cells[2].value = 'Country';
// Set header font
headerRow.style.font =
    PdfStandardFont(PdfFontFamily.helvetica, 10, style: PdfFontStyle.bold);
// Add rows to the grid
PdfGridRow row = grid.rows.add();
row.cells[0].value = 'ALFKI';
row.cells[1].value = 'Maria Anders';
row.cells[2].value = 'Germany';
// Add next row
row = grid.rows.add();
row.cells[0].value = 'ANATR';
row.cells[1].value = 'Ana Trujillo';
row.cells[2].value = 'Mexico';
// Add next row
row = grid.rows.add();
row.cells[0].value = 'ANTON';
row.cells[1].value = 'Antonio Mereno';
row.cells[2].value = 'Mexico';
// Set grid format
grid.style.cellPadding = PdfPaddings(left: 5, top: 5);
// Draw table to the PDF page.
grid.draw(
    page: page,
    bounds: Rect.fromLTWH(
        0, 0, page.getClientSize().width, page.getClientSize().height));
// Save the document
File('PDFTable.pdf').writeAsBytes(document.save());
// Dispose the document
document.dispose();

Add headers and footers

Use the following code to add headers and footers to a PDF document.

//Create a new PDF document
final PdfDocument document = PdfDocument();
//Create a PDF page template and add a header content
final PdfPageTemplateElement headerTemplate =
    PdfPageTemplateElement(const Rect.fromLTWH(0, 0, 515, 50));
//Draw text to the header
headerTemplate.graphics.drawString(
    'This is page header', PdfStandardFont(PdfFontFamily.helvetica, 12),
    bounds: const Rect.fromLTWH(0, 15, 200, 20));
//Add the header element to the document
document.template.top = headerTemplate;
//Create a PDF page template and add a footer content
final PdfPageTemplateElement footerTemplate =
    PdfPageTemplateElement(const Rect.fromLTWH(0, 0, 515, 50));
//Draw text to the footer
footerTemplate.graphics.drawString(
    'This is page footer', PdfStandardFont(PdfFontFamily.helvetica, 12),
    bounds: const Rect.fromLTWH(0, 15, 200, 20));
