Flutter file word readable-CodePudding

I want to write a file with flutter, that has got the same function as WORLD_READABLE in android. So i want tha this file can be read by all the applications. More clear: i have an app A that write hello.txt i want that another app B can read this file. How i should set my file? There is a parameter of some function in the package path_provider?

I seen the package path_provider and File class, but i didn't find something. I have already tried by access direct to file from app B, but is not world readable.

CodePudding user response：

Something like this should work and make sure you use the latest path_provider dependency. getExternalStorageDirectory() does the trick!

//Write file from App 1

 import 'dart:io';
 import 'package:path_provider/path_provider.dart';
    
 Future<void> writeToFile(String data) async {
   final directory = await getExternalStorageDirectory();
   final file = File('${directory.path}/hello.txt');
   await file.writeAsString(data);
    }

//Read the written file from App 2

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

Future<String> readFromFile() async {
  final directory = await getExternalStorageDirectory();
  final file = File('${directory.path}/hello.txt');
  return file.readAsString();
}
