如何在Flutter中禁用放大InAppWebView？

dependencies:
  flutter_inappwebview: ^5.3.2

import 'package:flutter_inappwebview/flutter_inappwebview.dart';

// 创建一个InAppWebView实例
InAppWebView webView = InAppWebView(
  initialUrlRequest: URLRequest(url: Uri.parse("https://example.com")),
  initialOptions: InAppWebViewGroupOptions(
    crossPlatform: InAppWebViewOptions(
      // 禁用放大
      supportZoom: false,
      // 禁用缩放控件
      builtInZoomControls: false,
    ),
  ),
);

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text("InAppWebView"),
    ),
    body: SafeArea(
      child: webView,
    ),
  );
}
