add method - StreamController class - dart:async library (original) (raw)

add abstract method

void add(

1. T event )

override

Sends a data event.

Listeners receive this event in a later microtask.

Note that a synchronous controller (created by passing true to the syncparameter of the StreamController constructor) delivers events immediately. Since this behavior violates the contract mentioned here, synchronous controllers should only be used as described in the documentation to ensure that the delivered events always appear as if they were delivered in a separate microtask.

Implementation

void add(T event);
