Does it support run on Chrome 107?

[xvrh]

Yes it should.
To prevent incompatibility issue, you probably want to use the version 2.16.0 of this library.

Post here if you have any specific error.

I will try

Hi @xvrh.
Is there any way I can use the library in the latest version of the code (bug fixed) but compatible with lower chrome versions, for example chrome 107?

[xvrh]

@ninhngadev it's possible that the latest version of this library works with chrome 107. But it's also possible that there is a breaking change in the protocol between v107 and v112.
Since Dart has a sound type system any small change can easily trigger a null assertion error.

But I recommend that you try and show us any error you run into.

I got a crash when run on chrome 107

@xvrh.
I just workaround by

but I don't know what the potential dangers would be in doing so.

[xvrh]

@ninhngadev yes this is exactly the kind of error I was expecting. Dart has sound null-safety now, so this is very easy to run into this kind of cast error when there is a version mismatch (between the version of the protocol and the chrome instance).

I think you can easily maintain your own fork of this library with your fixes applies to workaround the bug (until you can upgrade Chrome to a newer version).

[ninhngadev]

Thanks @xvrh.
I think it's safe to close this issue.
