How do I open a PDF document from Assets folder?

[clangenb]

Something like that should work:

// example asset: asset = 'assets/your_doc.pdf' 
  Future<PDFDoc> _pdfFromAsset(String asset) async {
    File file;
    try {
      var dir = await getApplicationDocumentsDirectory();
      file = File("${dir.path}/file.pdf");
      var data = await rootBundle.load(asset);
      var bytes = data.buffer.asUint8List();
      await file.writeAsBytes(bytes, flush: true);
    } catch (e) {
      throw Exception('Error parsing asset file!');
    }
    return await PDFDoc.fromFile(file);
  }

static Future pdfFromAsset(String asset) async {
File file;
try {
final filename = basename(asset);
var dir = await getApplicationDocumentsDirectory();

  var data = await rootBundle.load(asset);
  var bytes = data.buffer.asUint8List();
  file = File('${dir.path}/$filename');
  await file.writeAsBytes(bytes, flush: true);
} catch (e) {
  throw Exception('Error parsing asset file!');
}
PDFDoc doc = await PDFDoc.fromFile(file);
String docText = await doc.text;
return docText;

}
//after that you will load

final file = await pdfFromAsset(path);

"file":"doc2.pdf"
}
]
}
//then to load

Future readJson() async {
final String response = await rootBundle.loadString('assets/sample.json');
final data = await json.decode(response);
final pdfdata = data['pdfdata'];
