Installation

dependencies:
  docs_gee: ^1.2.2

dart pub add docs_gee
# or
flutter pub add docs_gee

Quick Start

import 'dart:io';
import 'package:docs_gee/docs_gee.dart';

void main() {
  // Create document
  final doc = Document(title: 'My Report', author: 'John Doe');

  // Add content
  doc.addParagraph(Paragraph.heading('Quarterly Report', level: 1));
  doc.addParagraph(Paragraph.text('This report summarizes Q4 performance.'));

  // Add a table
  doc.addTable(Table(
    rows: [
      TableRow(cells: [
        TableCell.text('Metric', backgroundColor: 'E0E0E0'),
        TableCell.text('Value', backgroundColor: 'E0E0E0'),
      ]),
      TableRow(cells: [
        TableCell.text('Revenue'),
        TableCell.text('\$1.2M', alignment: Alignment.right),
      ]),
    ],
  ));

  // Generate both formats
  File('report.docx').writeAsBytesSync(DocxGenerator().generate(doc));
  File('report.pdf').writeAsBytesSync(PdfGenerator().generate(doc));
}

Usage Examples

Rich Text Formatting

doc.addParagraph(Paragraph(
  runs: [
    TextRun('Normal, '),
    TextRun('bold, ', bold: true),
    TextRun('italic, ', italic: true),
    TextRun('colored', color: 'FF0000'),
  ],
));

Lists

// Bullet list
doc.addParagraph(Paragraph.bulletItem('First item'));
doc.addParagraph(Paragraph.bulletItem('Second item'));

// Numbered list
doc.addParagraph(Paragraph.numberedItem('Step one'));
doc.addParagraph(Paragraph.numberedItem('Step two'));

// Nested list
doc.addParagraph(Paragraph.bulletItem('Parent'));
doc.addParagraph(Paragraph.bulletItem('Child', indentLevel: 1));

Tables

doc.addTable(Table(
  borders: TableBorders.all(),
  rows: [
    TableRow(cells: [
      TableCell.text('Name', backgroundColor: 'CCCCCC'),
      TableCell.text('Score', backgroundColor: 'CCCCCC'),
    ]),
    TableRow(cells: [
      TableCell.text('Alice'),
      TableCell.text('95', alignment: Alignment.right),
    ]),
  ],
));

Cell Borders

Override table-level borders on individual cells:

doc.addTable(Table(
  borders: const TableBorders.all(),
  rows: [
    TableRow(cells: [
      // Cell with custom red borders
      TableCell.text('Alert', borders: const CellBorders.all(color: 'FF0000', size: 8)),
      TableCell.text('Normal cell'),
    ]),
    TableRow(cells: [
      // Cell with only bottom border
      TableCell.text('Underlined', borders: const CellBorders.bottom()),
      // Cell with no borders (overrides table borders)
      TableCell.text('Clean', borders: const CellBorders.none()),
    ]),
  ],
));

// Selective sides with different styles
TableCell(
  paragraphs: [Paragraph.text('Custom')],
  borders: const CellBorders(
    top: Border(color: 'FF0000', size: 8, style: BorderStyle.double),
    bottom: Border(color: '0000FF'),
  ),
);

Semantic Styles

doc.addParagraph(Paragraph.heading('Title', level: 1));
doc.addParagraph(Paragraph.subtitle('Document subtitle'));
doc.addParagraph(Paragraph.quote('A famous quote...'));
doc.addParagraph(Paragraph.codeBlock('const x = 42;'));
doc.addParagraph(Paragraph.caption('Figure 1: Chart'));

Page Breaks

doc.addParagraph(Paragraph.heading(
  'New Chapter',
  level: 1,
  pageBreakBefore: true,
));

Line Breaks (Soft Return) - DOCX only

Line breaks allow multiple lines within a single paragraph (like Shift+Enter in Word).

// Using \n in text (automatic conversion)
doc.addParagraph(Paragraph.text('Line 1\nLine 2\nLine 3'));

// Using explicit line break runs (for different formatting per line)
doc.addParagraph(Paragraph(
  runs: [
    TextRun('Bold line', bold: true),
    TextRun.lineBreak(),
    TextRun('Normal line'),
    TextRun.lineBreak(),
    TextRun('Italic line', italic: true),
  ],
));

Hyperlinks

// External link
doc.addParagraph(Paragraph(
  runs: [
    TextRun('Visit '),
    TextRun('our website', hyperlink: 'https://example.com'),
    TextRun(' for more info.'),
  ],
));

Internal Links (Bookmarks)

// Create a bookmark
doc.addParagraph(Paragraph.heading(
  'Chapter 1: Introduction',
  level: 1,
  bookmarkName: 'chapter1',
));

// Link to the bookmark
doc.addParagraph(Paragraph(
  runs: [
    TextRun('Go to '),
    TextRun('Chapter 1', bookmarkRef: 'chapter1'),
  ],
));

// Enable automatic Table of Contents
final doc = Document(
  title: 'My Document',
  includeTableOfContents: true,
  tocTitle: 'Contents',
  tocMaxLevel: 3,  // Include Heading 1-3
);

doc.addParagraph(Paragraph.heading('Introduction', level: 1));
doc.addParagraph(Paragraph.heading('Getting Started', level: 2));
// TOC will be auto-generated with links to these headings
