You can use only global variables.

Also you may solve this via private variables with "mangling" names.

void main() {
  myFunction();
  myFunction();
  myFunction();
}

int _myFunction$count = 0;

void myFunction() {
  print(_myFunction$count++);
}

This does not helps a lot but you can consider that variable with name "_myFunction$count" is a local static variable "count" in function "myFunction".

The same as this pseudo code.

void myFunction() {
  static int count = 0;
  print(count++);
}
