运行 flutter webview 时出错： E/MethodChannel#flutter/platform_views( 3411): Failed to handle method call 。 SUPPRESS_ERROR_PAGE

Question

我刚刚从https://docs.meetmighty.com/mightyweb/

购买了flutter webview源代码

我已经按照文档中的说明运行源代码但不成功，并显示错误如下：

我该怎么办？对不起，我的英语不好。请帮助我。

Answer 1

我也遇到了这个错误。我首先在 pubspec.yaml 中使用了这些版本的 webview。

webview_flutter: 4.8.0
flutter_inappwebview: ^6.0.0

然后我就改成了这些。

webview_flutter: 4.7.0
flutter_inappwebview: ^6.0.0

最后我添加了这个并且它起作用了。

dependency_overrides:
  webview_flutter_android: 3.16.1

所以最终设置是

  webview_flutter: 4.7.0
  flutter_inappwebview: ^6.0.0
dependency_overrides:
  webview_flutter_android: 3.16.1
