This article explains how to export a text content, json list or object in an flutter application to the device. See the following image for a preview.

Here we used the following code:

import 'dart:convert';
import 'package:share_plus/share_plus.dart';
import 'package:path_provider/path_provider.dart';
import 'dart:io';
import 'package:intl/intl.dart';Future convertStringToFileShare(BuildContext context, String imputListAsString) async {
  var filename = 'reperti_2022.par';
  final temp = await getTemporaryDirectory();
  final path = '${temp.path}/${filename}';
  
  File(path).writeAsString(imputListAsString);
  await Share.shareFiles([path]);
}void main() {   var fileContent = '{"text":"here is the content of the file"}';
   convertStringToFileShare(fileContent);}// call the function with the following command
// convertStringToFileShare("file content");

After you run the code the file explorer of the device should open and the user can choose the location of the file.

This article is to show you the basic operations to convert JSON objects in dart flutter.

JSON Object to String

import 'dart:convert';

After the import, you can add the following code or wrap it around a function.

const data = {'text': 'foo', 'value': 2, 'status': false};
final String jsonString = jsonEncode(data);
print(jsonString);// Output
// {"text":"foo","value":2,"status":false,"extra":null}

String to JSON Object

To convert a String into a object in dart use the following code:

const String responseAPIData = '[{"id":1,"name":"Service1"},{"id":2,"name":"Service2"}]';final dataResp = json.decode(responseAPIData);// Print the name of the second product in the list     print(dataResp[1]['name']);
// Output -> Service2
