Flutter edge-to-edge app not displaying contents behind a translucent system bar. How to fix? - Stack Overflow

My Flutter app already uses compileSdk and targetSdkVersion of 35, and I am using Android Virtual Device (AVD) of API level 35. (So, I am sure they are edge-to-edge capable?!) I started out my apps at API level 34, and despite now targeting 35, I have not made my apps edge-to-edge compatible. I assume that will be a requirement in future?! So, I am trying out this example edge-to-edge app to begin with. Here in this app, despite setting statusBarColor in SystemUiOverlayStyle to Colors.transparent, the status bar is still opaque, and the contents are not being drawn behind the status bar. What am I missing? How to fix this?

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';

void main() {
  // Make the app edge-to-edge
  WidgetsFlutterBinding.ensureInitialized();
  SystemChrome.setEnabledSystemUIMode(SystemUiMode.edgeToEdge);
  SystemChrome.setSystemUIOverlayStyle(
    const SystemUiOverlayStyle(
      statusBarColor: Colors.transparent, // Transparent status bar
      systemNavigationBarColor:
          Colors.transparent, // Transparent navigation bar (if applicable)
      systemNavigationBarDividerColor: Colors.transparent,
      statusBarIconBrightness:
          Brightness.dark, // Or Brightness.dark depending on your app's theme
      systemNavigationBarIconBrightness: Brightness.light,
    ),
  );

  runApp(const EdgeToEdgeApp());
}

class EdgeToEdgeApp extends StatelessWidget {
  const EdgeToEdgeApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Edge to Edge Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const EdgeToEdgeScreen(),
    );
  }
}

class EdgeToEdgeScreen extends StatelessWidget {
  const EdgeToEdgeScreen({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      // Important: Use SafeArea sparingly, and only where truly needed.
      // Often, padding and insets are better managed directly.
      // appBar: AppBar(title: const Text('Edge to Edge')),
      // The following property contentWindowInsets is supposed to work for
      // edge to edge, but Flutter 3.29.0 is not recognising it! Don't know why?
      // contentWindowInsets = WindowInsets(0.dp),
      body: Padding(
        // Use EdgeInsets.only to control specific padding.
        padding: EdgeInsets.only(
          top: MediaQuery.of(context).padding.top, // Top inset
          left: MediaQuery.of(context).padding.left, // Left inset
          right: MediaQuery.of(context).padding.right, // Right inset
          bottom: MediaQuery.of(context).padding.bottom, //Bottom inset
        ),
        child: ColoredBox(
          // Use ColoredBox for background color
          color: Colors.amber,
          child: ListView(
            children: [
              // Example content:
              Center(
                child: Column(
                  mainAxisAlignment: MainAxisAlignment.center,
                  children: <Widget>[
                    const Text('Edge to Edge!', style: TextStyle(fontSize: 24)),
                    const SizedBox(height: 20),
                    const Text(
                      'Content goes here. Scroll to see how insets are handled.',
                    ),
                    // Add more content to demonstrate scrolling
                    Container(height: 500, color: Colors.blue.withOpacity(0.3)),
                    Container(
                      height: 300,
                      color: Colors.green.withOpacity(0.3),
                    ),
                    Container(height: 200, color: Colors.red.withOpacity(0.3)),
                  ],
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}
