在flutter中有没有优化webview缓存的方法？

dependencies:
  flutter_inappwebview: ^5.3.2

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

class MyWebView extends StatefulWidget {
  @override
  _MyWebViewState createState() => _MyWebViewState();
}

class _MyWebViewState extends State<MyWebView> {
  InAppWebViewController? webViewController;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('WebView'),
      ),
      body: InAppWebView(
        initialUrlRequest: URLRequest(url: Uri.parse('https://example.com')),
        initialOptions: InAppWebViewGroupOptions(
          android: AndroidInAppWebViewOptions(
            cacheMode: AndroidCacheMode.LOAD_CACHE_ELSE_NETWORK,
          ),
          ios: IOSInAppWebViewOptions(
            allowsInlineMediaPlayback: true,
          ),
        ),
        onWebViewCreated: (controller) {
          webViewController = controller;
        },
      ),
    );
  }
}
