JavaScriptMessageHandler can not been trigered on Windows Platform

[RoleWong]

I tend to trigger the postMessage with the following codes on HTML.

But those JavaScriptMessageHandlers on Dart can not been triggered.

While this problems only occurs on Windows, but not macOS.

Found this PR #168, and I upgrade this package to to desktop_webview_window: ^0.2.0, and the code downloaded do includes the added code from this PR, but this still can not work.

[Update1: ] It seems caused by the following if, that prevent the platfrom aprt from macOS to register the handler. Can I just remove this judgment logic?

[Update2: ] Solution found: In this case, postMessage should be called as window.chrome.webview.postMessage(val); , and add a addOnWebMessageReceivedCallback listener on Dart layer. This issue can be cloused.
