Usage

var htmlContent =
"""
<!DOCTYPE html>
<html>
<head>
  <style>
  table, th, td {
    border: 1px solid black;
    border-collapse: collapse;
  }
  th, td, p {
    padding: 5px;
    text-align: left;
  }
  </style>
</head>
  <body>
    <h2>PDF Generated with html_to_pdf plugin</h2>
    <table style="width:100%">
      <caption>Sample HTML Table</caption>
      <tr>
        <th>Month</th>
        <th>Savings</th>
      </tr>
      <tr>
        <td>January</td>
        <td>100</td>
      </tr>
      <tr>
        <td>February</td>
        <td>50</td>
      </tr>
    </table>
    <p>Image loaded from web</p>
    <img src="https://i.imgur.com/wxaJsXF.png" alt="web-img">
  </body>
</html>
""";

var targetPath = "/your/sample/path";
var targetFileName = "example_pdf_file"

final generatedPdfFile = await HtmlToPdf.convertFromHtmlContent(
  htmlContent: htmlContent,
  printPdfConfiguration: PrintPdfConfiguration(
    targetDirectory: targetPath,
    targetName: targetFileName,
    printSize: PrintSize.A4,
    printOrientation: PrintOrientation.Portrait,
  ),
);

Code above simply generates PDF file from HTML content. It should work with most of common HTML markers. You don’t need to add .pdf extension to targetFileName because plugin only generates PDF files and extension will be added automatically.

Other Usages

You can also pass File object with HTML content inside as parameter

var file = File("/sample_path/example.html");
var generatedPdfFile = await HtmlToPdf.convertFromHtmlFile(
    file, targetPath, targetFileName);

or even just path to this file

var filePath = "/sample_path/example.html";
var generatedPdfFile = await HtmlToPdf.convertFromHtmlFilePath(
    filePath, targetPath, targetFileName);

Images

If your want to add local image from device to your HTML you need to pass path to image as src value.

<img src="file:///storage/example/your_sample_image.png" alt="web-img">

or if you want to use the image File object

<img src="${imageFile.path}" alt="web-img">

Many images inside your document can significantly affect the final file size so I suggest to use flutter_image_compress plugin.
