I want to cater to multiple restaurant clients, should i crea one firestore database with one top level collection for each client or should I create one firestore database for each client? each restaurant admin/owner should see their unique dashboard when they login to the Android app

How to copy the received data to local variable , as the function is asynchronous and return future string but my local variable is of type string 🤷🏻‍♂️🤔

[@mafiacodes]

u have to copy that inside the async function

[@bhupeshpattanaik7150]

@@mafiacodes for example: String x; Void a() async { x = 'hello'; } a(); Print ( x ) ; This says x is null and does not assigned it ,

[@mafiacodes]

Yes that’s true, you need to use a listener
