Getting Started

The package only has three functions getPDFtext(path), getPDFtextPaginated(path) and getPDFlength(path). Path is the file path to the PDF file you want to parse. I used file_picker package in the example to get the path of the PDF file.

Check the example for more details.

Example

getPDFtext(String path)

Returns text from PDF file as a String.

    Future<String> getPDFtext(String path) async {
    String text = "";
    try {
      text = await ReadPdfText.getPDFtext(path);
    } on PlatformException {
      print('Failed to get PDF text.');
    }
    return text;
  }

getPDFtextPaginated(String path)

Returns text from PDF but in a String list, where each item is a page of the PDF file.

  Future<List<String>> getPDFtextPaginated(String path) async {
    List<String> textList = List<String>();
    try {
      textList = await ReadPdfText.getPDFtextPaginated(path);
    } on PlatformException {
      print('Failed to get PDF text.');
    }
    return textList;
  }

getPDFlength(String path)

Returns length of the document as an integer.

  Future<int> getPDFlength(String path) async {
    int length = 0;
    try {
      length = await ReadPdfText.getPDFlength(path);
    } on PlatformException {
      print('Failed to get PDF length';)
    }
    return length;
  }
