Add Promise while calling method request in app review.

1- add callback if flow has finished, to be like

InAppReview.RequestInAppReview()
.then((hasFlowFinishedSuccessfully) => {

// The flow has finished. The API does not indicate whether the user
// reviewed or not, or even whether the review dialog was shown. Thus, no
// matter the result, we continue our app flow.

 console.log('InAppReview ', hasFlowFinishedSuccessfully);

})
.catch((error) => {
//we continue our app flow.

 console.log(error);
});
