jjcode flutter plugin

jjcode_flutter_plugin #
集成前必读： #
由于微信小程序和APP交互的限制，APP调起小程序要求APP必须在微信开放平台已经认证，如果没有认证无法调起微信小程序，集成前请先前往微信开放平台进行认证。如果已经集成过微信登录、微信支付或者微信的分享则可以直接使用。
一、安装 #
1.1 添加依赖
在项目的pubspec.yaml文件中添加以下内容:
dependencies:
jjcode_flutter_plugin: ^1.0.0

1.2 安装
通过命令行安装
flutter pub get

二、配置 #
Android配置
找到项目的AndroidManifest.xml文件，在<application>...</application>中增加以下配置
<meta-data
android:name="com.jijiancode.APP_ID"
android:value="[极简验证APP_ID]"/>
<meta-data
android:name="com.jijiancode.WX_APP_ID"
android:value="[微信开放平台APP_ID]"/>
copied to clipboard
iOS配置
在Info.plist中增加以下配置
<key>com.jijiancode.APP_ID</key>
<string> [极简验证APP_ID] </string>
<key>com.jijiancode.WX_APP_ID</key>
<string> [微信开放平台APP_ID] </string>

三、接口调用 #
这里假设当前Flutter应用使用fluwx来集成WechatSDK。
3.1. 导入接口定义
import 'package:jjcode_flutter_plugin/jjcode_flutter_plugin.dart';

3.2. 插件配置和接口调用
import 'package:fluwx/fluwx.dart' as fluwx;

class _MyAppState extends State<MyApp> {
late JjcodeFlutterPlugin _jjcodeFlutterPlugin;
@override
void initState() {
super.initState();
// 1. 初始化WechatSDK
_initFluwx();
initPlatformState();
}

_initFluwx() async {
await fluwx.registerWxApi(
appId: "wx5224379xxxxxxx",
doOnAndroid: true,
doOnIOS: true,
universalLink: "https://wwww.xxxxxx.com/ulink/");
}

Future<void> initPlatformState() async {
if (!mounted) return;

// 2. 初始化JjcodeFlutterPlugin
_jjcodeFlutterPlugin = JjcodeFlutterPlugin.getInstance();
_jjcodeFlutterPlugin.setWxHandler(wxHandler);

// 3. 监听微信小程序结果回调
fluwx.weChatResponseEventHandler.listen((res) {
if (res is fluwx.WeChatLaunchMiniProgramResponse) {
if (mounted) {
var extMsg = res.extMsg;
_jjcodeFlutterPlugin.handleWxResp(extMsg);
}
}
});
}

// 4. 定义wxHandler方法实现，用于桥接当前WechatSDK实现
Future<bool> wxHandler(String reqUserName, String reqPath) async {
return fluwx.launchWeChatMiniProgram(username: reqUserName, path: reqPath);
}

// 5. 定义verify 接口回调
Future responseHandler(Map<String, dynamic> data) async {
setState(() {
result = "verify result: \n\n"
+ "code= " + data['code'].toString() + "\n"
+ "msg= " + data['msg'].toString() + "\n";
});
}
}
