flutter sharesdk实现跨平台分享

flutter端

1.依赖sharesdk。

在https://pub.dartlang.org/packages/sharesdk中下载sharesdk1.0.8demo，并将其放入我们的项目中本地引用。这里我将其放入plugins目录下。
添加下列代码到pubspec.yaml进行本地引用:

dependencies:
  sharesdk: 
    path: plugins/sharesdk-1.0.8

2.安装。

在flutter 中使用下列命令来安装:

$ flutter packages get

3.使用它。

现在你可以在Dart代码中使用sharesdk。
下面我们在main.dart中来实现微信分享功能:

import ‘package:flutter/material.dart‘;
import ‘package:flutter/cupertino.dart‘;
import ‘package:sharesdk/sharesdk.dart‘;

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

class ShareApp extends StatefulWidget {
  @override
  State<ShareApp> createState() {
    return new _ShareAppState();
  }
}

class _ShareAppState extends State<ShareApp> {

  //初始化sharasdk 
  //这里只添加微信分享功能来进行测试
  //请先在微信开放平台中申请微信分享权限 并使用生成的AppID和AppSecret。
  initShareSDK() {
    ShareSDKRegister register = ShareSDKRegister();
    register.setupWechat(
          "wxcb24d644e340e9cc", "34a7656f86280f75e16cd9094a8a1f54");
    ShareSDK.regist(register);
  }

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

  void showAlert(SSDKResponseState state, Map content, BuildContext context) {
    String title = "失败";
    switch (state) {
      case SSDKResponseState.Success:
        title = "成功";
        break;
      case SSDKResponseState.Fail:
        title = "失败";
        break;
      case SSDKResponseState.Cancel:
        title = "取消";
        break;
      default:
        title = state.toString();
        break;
    }
    showDialog(
      context: context,
      builder: (BuildContext context) =>
        CupertinoAlertDialog(
            title: new Text(title),
            content: new Text(content != null ? content.toString() : ""),
            actions: <Widget>[
              new FlatButton(
                child: new Text("OK"),
                onPressed: () {
                  Navigator.of(context).pop();
                },
              )
            ]
        )
      );
  }

  userWeChatShare(BuildContext context) {
    SSDKMap params = SSDKMap()
                ..setGeneral(
                    "title",
                    "text",
                    null,
                    null,
                    null,
                    null,
                    null,
                    null,
                    null,
                    SSDKContentTypes.text);

    ShareSDK.share(ShareSDKPlatforms.wechatSession, params, (SSDKResponseState state, Map userdata, Map contentEntity, SSDKError error){
      showAlert(state, error.rawData, context);
    });
  }

  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      theme: new ThemeData(primaryColor: Colors.white),
      home: new Center(
        child:RaisedButton(
          onPressed:(){userWeChatShare(context);},
          child:Text("微信分享"),
        )
      )
    );
  }
}

android端

1.重新mobsdk.gradle文件来选择你需要使用的平台,我们这里只使用了微信。

apply plugin: ‘com.mob.sdk‘

MobSDK {
    appKey "2a6869394af80"
    appSecret "796421d6838fe1ecbef3b419d2c2bcb0"

    ShareSDK {
        //平台配置信息
        devInfo {

            Wechat {
                appId "wxcb24d644e340e9cc"
                appSecret "34a7656f86280f75e16cd9094a8a1f54"
            }
        }
    }
}

2.在Manifest清单文件中配置：tools:replace="android:name"

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="你的包名">
<application
   android:name = ".MyApplication"
   tools:replace="android:name">

3.编译过程中报错如下:

屏蔽掉报错的内容即可!如果需要使用QQ，需把相应的代码还原!

注意:如果跳转不到微信，请注意包名以及keystore是否与微信开放平台中的注册信息一致。

iOS端

1.自定义需要导入的分享平台.
目前我们只加入了微信分享功能，所以需要重新编辑 sharesdk.podspec 文件设置 dependency。

#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html
#
Pod::Spec.new do |s|
  s.name             = ‘sharesdk‘
  s.version          = ‘0.0.1‘
  s.summary          = ‘flutter plugin for sharesdk.‘
  s.description      = <<-DESC

  s.author           = { ‘Mob‘ => ‘mobproducts@163.com‘ }

end
