网页浏览是否在抖动的网页中? [英] Do the webview in flutter cached web page?

问题描述

我想缓存显示在Flutter Webview中的网页，从而提高性能，而无需重新加载页面.有空吗?我可以实施吗?

解决方案

flutter_inappwebview(以前为flutter_inappbrowser)
具有参数cacheEnabled，默认值为ture
cacheEnabled:设置WebView是否应使用浏览器缓存.默认值为true

flutter_webview_plugin社区版本
具有参数appCacheEnabled以启用缓存

WebviewScaffold(
    key: _scaffoldKey,
    url: widget.url,
    clearCache: true,
    appCacheEnabled: true,      
);

webview_flutter官方版本
不提供参数，可以查看Android源代码 https://developer.android.com/reference/android/webkit/WebSettings# LOAD_DEFAULT
默认缓存使用模式.如果导航类型没有任何特定行为，请在缓存资源可用且未过期时使用缓存的资源，否则请从网络加载资源

I want to cache the web page I display in flutter webview so to improve my performance, no need to reload the page. Is that available? and can I implement it?

解决方案

flutter_inappwebview(former flutter_inappbrowser)
Has parameter cacheEnabled and default is ture
cacheEnabled: Sets whether WebView should use browser caching. The default value is true

flutter_webview_plugin community version
Has parameter appCacheEnabled to enable cache

WebviewScaffold(
    key: _scaffoldKey,
    url: widget.url,
    clearCache: true,
    appCacheEnabled: true,      
);

webview_flutter official version
Do not provide parameter , you can check with Android Source code https://github.com/flutter/plugins/blob/master/packages/webview_flutter/android/src/main/java/io/flutter/plugins/webviewflutter/FlutterWebView.java

default cache mode depend on iOS WKWebView and Android WebView
default cache mode of Android WebView is LOAD_DEFAULT https://developer.android.com/reference/android/webkit/WebSettings#LOAD_DEFAULT
Default cache usage mode. If the navigation type doesn't impose any specific behavior, use cached resources when they are available and not expired, otherwise load resources from the network
