Application crashes when trying to open webview-windows in flutter desktop

**Using desktop_multi_window package crated a new window from a flutter windows application
and when created and opened new window with this browser component it fails with this error

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method isWebviewAvailable on channel webview_window)
#0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:313:7)

#1 WebviewWindow.isWebviewAvailable (package:desktop_webview_window/desktop_webview_window.dart:56:19)
**

_with another plugin also same issue

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: MissingPluginException(No implementation found for method initialize on channel io.jns.webview.win)
#0 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:313:7)

https://github.com/jnschulze/flutter-webview-windows/issues/2 WebviewController.initialize (package:webview_windows/src/webview.dart:172:11)_

Any thing i missed or any suggestions.

Start by reproducing the crash with desktop_multi_window and desktop_webview_window in a Flutter Windows application. Inspect desktop_webview_window/lib/desktop_webview_window.dart at WebviewWindow.isWebviewAvailable and compare the reported webview_windows initialization path. Done means the new window can invoke the webview plugin without a MissingPluginException.
