Flutter pdf file isnt saving and showing error - flutter

Question

I am trying to simple generate and save pdf issue is its showing error in my code
I am doing like this
import 'package:path_provider/path_provider.dart';
import 'package:pdf/pdf.dart';
import 'package:pdf/widgets.dart' as pw;
onTap: () async{
final pdf = pw.Document();
pdf.addPage(
pw.Page(
build: (pw.Context context) => pw.Center(
child: pw.Text('Hello World!'),
),
),
);
// Share.shareFiles([pdf], text: 'Reports');
final output = await getTemporaryDirectory();
final path = "${output.path}/temp.pdf";
final file = File(path); // here its showing error 2 positional
await file.writeAsBytes(pdf.save()); // here its showing The method 'writeAsBytes' isn't defined for the type 'File'.
},
Plugin versions
pdf: 2.1.0 & path_provider: ^2.0.2
I search every where but I didnt find any solution cant find it so why I am getting this error -_-

Answer 1

Use io library to write the file:
import 'dart:io' as io;
onTap: () async{
final pdf = pw.Document();
pdf.addPage(
pw.Page(
build: (pw.Context context) => pw.Center(
child: pw.Text('Hello World!'),
),
),
);
// Share.shareFiles([pdf], text: 'Reports');
//replace your code to save file from bellow
final output = await getTemporaryDirectory();
final path = "${output.path}/temp.pdf";
final file = await io.File(path).writeAsBytes(pdf.save());
},
The error would be due to methods defined in the pdf library. You can use default io library to solve that.
