flutter setstate in dialog code example

Example 1: flutter how to setstate over alertdialog

showDialog(
  context: context,
  builder: (context) {
    String contentText = "Content of Dialog";
    return StatefulBuilder(
      builder: (context, setState) {
        return AlertDialog(blah blah blah....)})})

Example 2: flutter Dialog TextField setState

A very simple solution is to create another stateful widget that renders the content of the dialog. Then, any invocation of the setState will rebuild the content of the dialog.
