Steps to reproduce

1. Have a DatePickerDialog in your app that can reach its widest form, and have M3 enabled
2. Run the app. (I tried macos, CanvasKit, and skwasm)
3. Open the date picker if necessary
4. Adjust screen so DatePicker can be in its widest mode
5. Find the "Switch to input" button in the lower left corner

Expected results

The "Switch to input" button in the lower left corner should have some margin from the side of the dialog, similar to the narrower view.

Actual results

The "Switch to input" button is directly against the side of the dialog.

Code sample

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Center(
          child: DatePickerDialog(
            firstDate: DateTime.utc(2010),
            lastDate: DateTime.utc(2030),
          ),
        ),
      ),
    );
  }
}
