@szwang1 jschannel for webview_cef is very similar to webview_flutter, but not really same. we don't need to call postMessage. just use Print("hello-from js") is a true way,when you called it, flutter will print "hello-from js" on console board, and call the jscallback if you set. we can send a callback function use like Print("hello-from js",function abc(e){console.log(e);}) , then you will find 'e' is second param you set at sendJavaScriptChannelCallBack.

yeah! I used Print and it worked before but now nothing happened. No console log and no error.
But I found flutter error during macos development below, something wring?

@SinyimZhi @hlwhl I am using the latest package of webview_cef on windows ,I tried to post message in JS and get the same error in console "Uncaught ReferenceError: Print is not defined" as shown in the attached snapshot . It would be helpful if you can share code snippet showing how to send message from JS to Flutter and vice versa?
If I have to send string data to and from JS how can I do it with this package?
Your help is much appreciated.

@RakshithSarja @szwang1 sry, i was on vacation a while ago. Actually, my code is in example/main.dart. According to the error message, it seems to be a unique issue on the Mac because the v8 engine is not working properly. We will try to fix this issue on Mac, but it may take a lot of time as our technology stack is mostly on Windows and Linux.

HI @SinyimZhi Thanks for your response. The issue what I am facing is on windows only.

@RakshithSarja if you change the url , you should excute jschannels or any js code you want to provide to web agin.

I have conducted an in-depth investigation into the error message you mentioned and found that the error message may be caused by various issues. 1. As the Pod-related frameworks introduce parameters that are automatically generated, there may be a formatting issue that requires adjustments to the automation script.Reference document:https://developer.apple.com/forums/thread/47579、https://developer.apple.com/forums/thread/698628.
2.Xcode itself may introduce bugs. Reference documents: https://discuss.circleci.com/t/xcode-15-beta-4-released/48645, nodejs/node-gyp#569

is there any solution about this issue ,i found same issue on my mac

@SinyimZhi>@szwang1webview_cef 的 jschannel 与 webview_flutter 非常相似,但并不完全相同。我们不需要调用 postMessage。只需使用 Print("hello-from js") 才是真正的方法,当你调用它时,flutter 会在控制台上打印“hello-from js”,并根据你的设置调用 jscallback。我们可以发送一个回调函数,如_Print("hello-from js",function abc(e){console.log(e);})_,然后你会发现 'e' 是你在 sendJavaScriptChannelCallBack 设置的第二个参数。
是的!我使用“打印”,以前可以用,但现在什么也没发生。没有控制台日志,也没有错误。
但是我在下面的macos开发过程中发现flutter错误,有什么问题吗?

你这不是没通啊,你没写回调函数啊。。。undifined代表你Print函数没有任何返回值。这个Print函数的功能是在flutter的控制台输出你在js控制台传给Print函数的第一个参数,第二个参数可选参数,是你要在js侧定义的回调函数。sendJavaScriptChannelCallBack传递回去的参数是需要你在js测定义的函数来处理的。你看看我截图里是如何调用Print函数的,我在调用Print函数时也是输出undefined的,我的message输出是我传递的回调函数里的console.log(e)输出的。e就是sendJavaScriptChannelCallBack传递回js侧的参数。

webview_textinput 这个文件我目前的flutter的版本低,所有我把这个也屏蔽了
// @OverRide

download.cmake 这个文件里边我修改了下载zip的地址, 只是把gitHub的下载下来传到我的文件服务器了,这个应该不影响吧

你截图的地方影响的,这个是把cef的回调从cef消息循环线程传递到flutter engine线程的PostMessage.因为flutter官方不建议method channel的invoke在非flutter engine线程调用,所以这里做了个传递。你这行注释掉就没有cef消息循环线程到flutter engine线程间的通讯了 @903531306 这里不应该报错的,你把报错信息详细点的发我看看。

我尝试调整了setJavaScriptChannels的调用时机,发现可能是由于同时加载两个页面,第二个页面的某些加载流程可能需要等第一个页面完全加载完成才能继续(尤其是第二个页面的url和第一个相同时)。目前我们example的写法并没有等待页面加载完成之后(或者说js引擎加载完成之后)才注入jschannel,实际上是不合适的,建议在onurlchanged的回调里去注入jschannel,这样能保证我们的jschannel注入成功,我这边也会调整example的写法。
