I'm not sure they even monitor these issues anymore. I have been waiting 3 weeks for an answer to my build issue.

@AzharKV, I have contacted support within the dashboard, and I'm waiting for a reply. To make sure it wasn't our code, I created a new project and only added the 100ms flutter component. I get the same error message you are getting. So it is their code, not ours.

[AzharKV]

Thanks @pqthealth.

@AzharKV not sure if you fixed it or not but it was settings inside flutter after I upgraded flutter and dart. I ran the following command, in terminal, to make sure flutter was pointing toward the right JDK version.

flutter config --jdk-dir <path_to_jdk>

I hope this helps if you haven't already found a solution.
