问题


Is there any lib/package that will help in both platform iOS and Android to share image+text+url on FB, Twitter And Insta? I have been searing for 4 hours but didn't find any result. https://pub.dev/packages/flutter_share_me this package is only for android so. If you have any solution for it please guide me.

~ PS : I don't want to use Share package, I have buttons of FB, Insta and Twitter. When user will click on any one of the button then data should be share on any of the social media and I need call back of failure or success.

full social_share_plugin example code

import 'package:flutter/material.dart';
import 'dart:async';
import 'dart:io';

import 'package:flutter/services.dart';
import 'package:social_share_plugin/social_share_plugin.dart';
import 'package:image_picker/image_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      platformVersion = await SocialSharePlugin.platformVersion;
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

You can use package https://pub.dev/packages/esys_flutter_share
github https://github.com/esysberlin/esys-flutter-share
iOS need special action, you can see IMPORTANT Note for iOS

Share text:

Share.text('my text title', 'This is my text to share with other applications.', 'text/plain');

Share file:

final ByteData bytes = await rootBundle.load('assets/image1.png');
await Share.file('esys image', 'esys.png', bytes.buffer.asUint8List(), 'image/png', text: 'My optional text.');

Share files:

final ByteData bytes1 = await rootBundle.load('assets/image1.png');
final ByteData bytes2 = await rootBundle.load('assets/image2.png');
final ByteData bytes3 = await rootBundle.load('assets/addresses.csv');

await Share.files(
    'esys images',
    {
        'esys.png': bytes1.buffer.asUint8List(),
        'bluedan.png': bytes2.buffer.asUint8List(),
        'addresses.csv': bytes3.buffer.asUint8List(),
    },
    '*/*',
    text: 'My optional text.');

Share file from url:

var request = await HttpClient().getUrl(Uri.parse('https://shop.esys.eu/media/image/6f/8f/af/amlog_transport-berwachung.jpg'));
var response = await request.close();
Uint8List bytes = await consolidateHttpClientResponseBytes(response);
await Share.file('ESYS AMLOG', 'amlog.jpg', bytes, 'image/jpg');
