```dart
sendWeChatAuth(scope: "snsapi_userinfo", state: "wechat_sdk_demo_test");
```

Why isn't user information retrieval supported?

User information retrieval should be handled by the backend. Even without a backend, you can implement this functionality directly in your Dart code.

Launching App from H5

Fluwx supports launching your app from <wx-open-launch-app> tags in H5 pages, with support for passing extInfo to your app.

For Android: Add the following intent filters to your AndroidManifest.xml:

```xml
<intent-filter>
<action android:name="${applicationId}.FlutterActivity" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data
android:host="${applicationId}"
android:path="/"
android:scheme="wechatextmsg" />
</intent-filter>
```

Additionally, add the following meta-data tag with your App ID:

```xml
<meta-data
android:name="weChatAppId"
android:value="12345678" />
```

To pass extInfo to Flutter, add this code to your MainActivity:

```kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// If you didn't configure WxAPI, add the following code
WXAPiHandler.setupWxApi("wxd930ea5d5a258f4f", this)
// Get Ext-Info from Intent
FluwxRequestHandler.handleRequestInfoFromIntent(intent)
}
```

For custom implementation logic, add this meta-data tag:

```xml
<meta-data
android:name="handleWeChatRequestByFluwx"
android:value="false" />
```

Then implement your custom logic in FluwxRequestHandler.customOnReqDelegate.

Android 11 Compatibility

Add the following queries to your app's AndroidManifest.xml:

```xml
<queries>
<intent>
<action android:name="${applicationId}.FlutterActivity" />
</intent>
<intent>
<action android:name="android.intent.action.VIEW" />
<data
android:host="${applicationId}"
android:path="/"
android:scheme="wechatextmsg" />
</intent>
</queries>
```

iOS Implementation

In your AppDelegate, actively register WXApi:

```objective-c
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Register with WeChat
[[FluwxDelegate defaultManager] registerWxAPI:@"" universalLink:@""];
return YES;
}
```
