Each param isn't necessary.However,if `appId`is blank, or `doOnAndroid: false`, or `doOnIOS: false`,you must register your `WXApi` on the particular platform in order to ensure `Fluwx` can work.
After tha,add the following code before using `Fluwx` on the particular platform:
For Android:
```kotlin
FluwxShareHandler.setWXApi(wxapi)
```
For iOS:
```objective-c
isWeChatRegistered = YES;
```
```
> NOTE:Although we can register WXApi via Fluwx,but there's still some work you have to do on the particular platform.For example, creat a `WXEntryActivity` for android and add a URLSchema for iOS.
