How to create and share the contact in flutter?

How to create the contact in locally with Name and phone number and share the created contact to other apps like whatsapp, social media's etc...

By using vcard_maintained library https://pub.dev/packages/vcard_maintained, we are able to create the contact, But not able to share through the apps.

I tried this,

import 'package:share_plus/share_plus.dart';
import 'package:vcard_maintained/vcard_maintained.dart';

var vCard = VCard();
vCard.firstName = 'FirstName';
vCard.middleName = 'MiddleName';
vCard.workPhone = '312-555-1212';
final path = await _localPath;
vCard.saveToFile('$path/contact.vcf');
Share.shareFiles(['$path/contact.vcf'], text: 'Great picture');


Future<String> get _localPath async {
  final directory = await getApplicationDocumentsDirectory();
  return directory.path;
}

But getting format of this vcard is not support error.

Solution

This is the working example.

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';
import 'package:path_provider/path_provider.dart';
import 'package:share_plus/share_plus.dart';
import 'package:vcard_maintained/vcard_maintained.dart';

void shareAllVCFCard(BuildContext context, {required List<VCard> vCard}) async {
  try {
    List<String> vcsCardPath = <String>[];
    int index = 0;
    for (final card in vCard) {
      index++;
      var vCardAsString = card.getFormattedString();
      final directory = await getApplicationDocumentsDirectory();
      final path = directory.path;
      var pathAsText = "$path/$index.txt";

      var contactAsFile = File(await getFilePath(index.toString()));
      contactAsFile.writeAsString(vCardAsString);

      var vcf = contactAsFile
          .renameSync(contactAsFile.path.replaceAll(".txt", ".vcf"));
      vcsCardPath.add(vcf.path);
    }

    Share.shareFiles(vcsCardPath, text: 'Great picture');
  } catch (e) {
    print("Error Creating VCF File $e");
    return null;
  }
}


Future<String> getFilePath(String fileName) async {
  Directory appDocumentsDirectory =
      await getApplicationDocumentsDirectory(); // 1
  String appDocumentsPath = appDocumentsDirectory.path; // 2
  String filePath = '$appDocumentsPath/$fileName.txt'; // 3

  return filePath;
}
