Assume we are creating a stateful widget with a single property (or field) as follows

int counter;

I found two ways to modify the counter:

  • First approach

    counter++;
setState((){}); // empty setState

  • Second approach

    setState((){counter++;}); // wrapping setState

Question

Either approach produces the same result. The updated counter are shown visually in a Text widget for example. I am wondering whether there are any other differences that are hard to see visually.

  • I would like to make a note that I retracted the answer I just posted, as I was not aware of the subtlety that calling setState in the two ways you've mentioned are meant to be equivalent.
