如何在Flutter中隐藏webview中的页眉和页脚？

webview_flutter: ^2.0.0

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

class WebViewExample extends StatelessWidget {
  final String url = 'https://example.com'; // 替换成你需要加载的URL

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('WebView Example'),
      ),
      body: WebView(
        initialUrl: _hideHeaderFooter(url),
        javascriptMode: JavascriptMode.unrestricted,
      ),
    );
  }

  String _hideHeaderFooter(String url) {
    // 在URL后面添加自定义的CSS样式
    return '$url#headerFooterStyle';
  }
}
