Please share a minimal and complete code sample along with the output of flutter doctor -v along with the complete error logs.
Were you running the Flutter code on an emulator or simulator? If so, what happens when you run on a physical device? What happens if you delete the print statement?
Without additional information we're unfortunately not sure how to resolve this issue. We're going to close this bug for now, but please don't hesitate to comment on the bug if you have any more information for us; we're happy to reopen. Thanks for your contribution!
My apologies, Steve, for the delay in responding.

I was running the code on Edge.
I removed the FlutterClipboard code and the same exception appeared, and I think it's because the list size exceeds a million items! Although the list was created and the list length was printed as shown in the screenshot.
I took a screenshot of the exception and attached it to the comment. I hope it will help you.

What was I trying to do? I was trying to print all the printable characters in ASCII code. Even after trying to print the characters in small numbers and showing them in the run console, there are many characters that don't look good like emojis for example because they have more than one value in the ASCII Code so I'd better convert them to Unicode instead of ASCII.
I wasn't able to exactly reproduce the problem, but I did cause Android Studio to become unresponsive. I think trying to print a million-character string broke it. I did not get an exception but I had to force-quit Android Studio.
I see this in your original report:
Caused by: java.lang.OutOfMemoryError: Java heap space
I probably have my IDE configured with enough memory to handle the string, and it was probably trying to print the string but I got tired of waiting for it to finish.
@jacob314 I'm tempted to close this issue. Is this use-case something we want to encourage? The user is using a Flutter app to print a million characters to the console in the IDE.
