- UnityViewPackage.
into android\app\src\main\java\com\samplereactnativeapp
copy react component from "SampleReactNativeApp\src\components\UnityView"
import UnityView from '../components/UnityView';
...
function UnityScreen(props) {
const onUnityMessage = hander => {

...
</UnityView>
)
}you can call any methode of any gameObject in untity project. the only limitation is that param must be a string
import {unityModule} from '../components/UnityView';

new {
...
}),
callBack = (data) =>{
