Small gap appers when switching between two screens with different aspect ratios

[leonardoCaceres]

If you implement a custom Windows title bar alongside a Scaffold, an issue may occur when switching between two screens with different layouts.
This is likely due to a mismatch in component sizing between the two screens.

Example:

MWE:

import 'package:flutter/material.dart';
import 'package:bitsdojo_window/bitsdojo_window.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';

void main() {
  runApp(const MyApp());
  doWhenWindowReady(() {
    appWindow.minSize = const Size(640, 480);
    appWindow.size = const Size(1200, 680);
    appWindow.alignment = Alignment.center;
    appWindow.show();
  });
}

class MyApp extends ConsumerWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context, WidgetRef ref) {
    return MaterialApp(
      home: Column(
        children: [
          Container(
            color: Colors.amber,
            child: WindowTitleBarBox(
              child: Row(
                children: [
                  Expanded(child: MoveWindow(child: SizedBox(height: 35))),
                ],
              ),
            ),
          ),
          Expanded(child: MyHomePage(title: "MWE")),
        ],
      ),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.amber,
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text('You have pushed the button this many times:'),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ),
    );
  }
}
