Flutter has the MethodChannel for sending data from Flutter to Java/Kotlin. We can also return values in these calls. But what if I want to return data at random times from Java/Kotlin to Flutter?
I remember there is a kind of channel to send data from Java to Flutter, but I forgot its name
CodePudding user response：
EventChannel or MethodChannel can be used to pass data from flutter to android and android to flutter. In your case android to flutter, you can read this blog: https://testfairy.com/blog/native-communication-with-a-callback-in-flutter/
