flutter_webview_plugin版本0.3.11，替换FlutterWebviewPlugin.java即可，如下

            final FlutterWebviewPlugin instance = new FlutterWebviewPlugin(registrar.activity(), registrar.activeContext());
            registrar.addActivityResultListener(instance);
            channel.setMethodCallHandler(instance);
        }
    }

        this.activity = activity;
        this.context = context;
        Log.i("FlutterWebView", "activity: " + activity + ", context: " + context);
    }

    @Override

        switch (call.method) {
            case "launch":
