[dart-misc] Access the caller instance from a function.

[Gonzalo Chumillas]

How could I access the "caller" instance from a function. The following
code throws a syntax error:

// Error: Local variables cannot be referenced before they are declared
Function listener = (Event event) {
print(listener);
};

I would like to access the "listener" variable from inside the function.
Thanks.

What a silly question :D Solved:

Function listener;
listener = (Event event) {
print(listener);
}

Or even:

listener(Event event) {
print(listener);
}
