Undefined name WebView in flutter

问题

I'm now having some trouble regarding Undefined name WebView. I'm using minSdkVersion 20 in build.gradle. This is what I have and this error only happened when I upgraded my flutter version to 3.7.11 today.

pubspec.yaml

webview_flutter: ^4.1.0

webviewpage.dart

import 'package:webview_flutter/webview_flutter.dart';

......
void initState() {
    super.initState();
    if (Platform.isAndroid) WebView.platform = AndroidWebView(); // Webview undefined error
}

....
child: WebView( // The method 'WebView' isn't defined for the type '_WebViewPageState'
           zoomEnabled: false,

How can I possibly resolve this error?

得分: 1

这是因为 webview_flutter: ^4.1.0 不再使用 WebView 类。

第一个可能的解决方案是将 webview_flutter 降级到版本 3.0.4。

第二个解决方案是根据这里描述的方式更新您的代码,以适用于当前版本的 webview_flutter

英文:

This is because the webview_flutter: ^4.1.0 does not use WebView class anymore.

First possible solution is downgrading your webview_flutter to version 3.0.4

Second solution: you have to update your code as it described here for the actual version of webview_flutter.
