There are many ways to solve this problem, override initState method:

@override
void initState() {
  super.initState();
  // Use any of the below code here. 
}

• Using SchedulerBinding mixin:

  SchedulerBinding.instance.addPostFrameCallback((_) {
    // Call your function
  });
  

• Using Future class:

  Future(() {
    // Call your function
  });

  Timer(() {
    // Call your function
  });
