Current Behavior

截屏2024-12-24 16 53 14

Expected Behavior

The background of InAppWebView is transparent, thus showing the red color set in Container.

Steps with code example to reproduce

import 'package:flutter/material.dart';
import 'package:flutter_inappwebview/flutter_inappwebview.dart';
import 'package:window_manager/window_manager.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await windowManager.ensureInitialized();
  await _initWindow();
  runApp(const MyApp());
}

Future<void> _initWindow() async {
  const windowOptions = WindowOptions(
    center: true,
    title: 'InAppWebView Demo',
  );
  await windowManager.waitUntilReadyToShow(windowOptions, () async {
    await windowManager.show();
    await windowManager.focus();
  });
}

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'InAppWebView Demo',
      home: Scaffold(
        body: Container(
          color: Colors.red,
          child: InAppWebView(
            initialData: InAppWebViewInitialData(data: """
            <!DOCTYPE html>
            <html lang="en">
            <head>
                <meta charset="UTF-8">
                <meta name="viewport" content="width=device-width, initial-scale=1.0">
                <title>InAppWebView Demo</title>
                <style> html,body { background-color: transparent; } </style>
            </head>
            <body>
              Test
            </body>
            </html>"""),
            initialSettings: InAppWebViewSettings(
              transparentBackground: true,
              isInspectable: true,
            ),
          ),
        ),
      ),
    );
  }
}
