How to avoid orientation changes when keyboard open with OrientationBuilder in Flutter?

Question

how to avoid orientation changes when keyboard is opened with OrientationBuilder in Flutter ?

Indeed when the keyboard appears the orientation property of OrientationBuilder changes to landscape even if we don't rotate the phone.

Image:

Code :

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
          body: OrientationBuilder(builder: (context, orientation) {
            var _children = [
              Expanded(
                  child: Center(
                      child: Text('Orientation : $orientation',
                          textAlign: TextAlign.center))),
              Flexible(
                  child: Container(color: Colors.blue, child: TextField())),
              Flexible(child: Container(color: Colors.yellow)),
            ];
            if (orientation == Orientation.portrait) {
              return Column(
                  mainAxisAlignment: MainAxisAlignment.spaceAround,
                  children: _children);
            } else {
              return Row(
                  mainAxisAlignment: MainAxisAlignment.spaceAround,
                  children: _children);
            }
          })),
    );
  }
}
