与Twitter/Facebook/Instagram分享url + image + text [英] Share url+image+text with Twitter/Facebook/Instagram

问题描述

在iOS和Android平台上是否有任何库/软件包将有助于在FB，Twitter和Insta上共享image + text + url?我已经灼烧了4个小时，但没有找到任何结果.

完整的social_share_plugin示例代码

  import'package:flutter/material.dart';导入'dart:async';导入'dart:io';导入'package:flutter/services.dart';导入'package:social_share_plugin/social_share_plugin.dart';导入'package:image_picker/image_picker.dart';void main()=>runApp(MyApp());MyApp类扩展了StatefulWidget {@override_MyAppState createState()=>_MyAppState();}类别_MyAppState扩展了State< MyApp>{字符串_platformVersion ='未知';@override无效的initState(){super.initState();initPlatformState();}//平台消息是异步的，因此我们使用async方法进行初始化.Future< void>initPlatformState()异步{字符串platformVersion;//平台消息可能会失败，因此我们使用try/catch PlatformException.尝试 {platformVersion =等待SocialSharePlugin.platformVersion;} on PlatformException {platformVersion ='无法获取平台版本.';}//如果在异步平台上将小部件从树中删除//邮件正在发送中，我们希望放弃回复，而不是调用//setState以更新我们不存在的外观.如果(！已安装)返回;setState((){_platformVersion = platformVersion;});}@override窗口小部件build(BuildContext context){返回MaterialApp(家:脚手架(appBar:AppBar(标题:const Text('Plugin example app')，)，正文:列(子代:< Widget> [中心(子代:Text(运行于:$ _ platformVersion \ n")，)，加高按钮(子级:Text('Share to Instagram')，onPressed:()异步{文件文件=等待ImagePicker.pickImage(source:ImageSource.gallery);等待SocialSharePlugin.shareToFeedInstagram("image/*"，file.path);}，)，加高按钮(子级:Text('Share to Facebook')，onPressed:()异步{文件文件=等待ImagePicker.pickImage(source:ImageSource.gallery);等待SocialSharePlugin.shareToFeedFacebook('test'，file.path);}，)，加高按钮(子级:Text('Share to Facebook Link')，onPressed:()异步{字符串url ='https://flutter.dev/';最终报价="Flutter是Google的便携式UI工具包，可通过单个代码库为移动，Web和桌面构建漂亮的，本机编译的应用程序."最终结果=等待SocialSharePlugin.shareToFeedFacebookLink(Quote:报价，网址:url，onSuccess:(postId){print('FACEBOOK SUCCESS $ postId');返回;}，onCancel:(){打印('FACEBOOK CANCELLED');返回;}，onError :(错误){print('FACEBOOK ERROR $ error');返回;}，);打印(结果);}，)，加高按钮(子代:文字(分享到Twitter")，onPressed:()异步{字符串url ='https://flutter.dev/';最终文本="Flutter是Google的便携式UI工具包，可通过单个代码库为移动，Web和桌面构建漂亮的，本机编译的应用程序."最终结果=等待SocialSharePlugin.shareToTwitter(文字:文字，网址:url，onSuccess:(_){打印('TWITTER SUCCESS');返回;}，onCancel:(){打印('TWITTER CANCELLED');返回;});打印(结果);}，)，]，)，)，);}} 

您可以使用软件包

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.

解决方案

Edit
package social_share_plugin https://github.com/romatroskin/social_share_plugin
provide share function and have call back
description page forget to mention twitter already include

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');
