onclose of modal reload screen flutter

Every Navigator push metod is async - you can wait till it poped

showModalBottomSheet under the hood pushes route to navigator, so you can 
rebuild your parent after bottomSheet closed this way

// somewhere in statefull parent
onTap:() async {
  await showModalBottomSheet();
  setState((){});
}
