Idea for sending direct message from user to user...

[Souvik Dutta]

He guys,

Suppose I want to make an uber clone in flutter, I want to send drivers notification about a ride when an user orders one. I am using firebase as backend to store and retrieve data and also to figure out the nearest drivers. But I am stuck at sending the driver a message of an user wanting a ride. Any ideas on how to do this will be greatly appreciated... 

Thank you.

Firebase cloud messaging is one mechanism to send notifications to users who are active in the app or the app is closed. There are other 3rd party alternatives. Given the 'uber' driver keeps the app active all the time, I would look at using a listener on a database node used to 'flag' new lift requests eg. a data item is added or changed. I would then use a pop up dialogue to inform the driver.

Okay. This is good but I was thinking about a more cost effective solution. I mean to just notify a driver I will have to do a minimum of two reads and writes. But I will give it a try.

Maybe should use FB Realtime db for it. You only pay for data downloaded volumes.
