cloud function execution url as callback url
I created a cloud function and used the generated url as callback URL so that the function will be triggered each time I need a response from a third party API but I wasn't able to fetch the data it was sending to my function (what I used as the call back url) despite using both context.body and context.rawBody for dart.
TL;DR
Cloud function created with callback URL not receiving data from third-party API. Use `context.req.body` in Dart function to fetch data. 
should be context.req.body.
TypeScript
Future<dynamic> main(final context) async {
final bodyRaw = context.req.bodyRaw;
final body = json.encode(context.req.body);
return context.res.send("OK", 200);
}
