Stop scrolling the console to the bottom when multiple errors are shown

[InMatrix]

Steps to Reproduce

• Run this app: https://github.com/InMatrix/flutter_error_studies/
• Tap "Unbounded Viewport" in the homepage of the app
• Observe output in the logging console

The first error is the root cause, and all subsequent errors are derivative. The full log has 655 lines with the "show structured error" setting on. The logging console will scroll to the bottom automatically. I need to then scroll back to the top. It would be more difficult if I had existing content in the console before this error occurred.

Shouldn't we reformulate the error or the error display so that in general we don't need to more than a page or two of console output to display the error?

[InMatrix]

The full log includes multiple errors, each of which is not too long. I added a link to the log in the top comment. So reformulating individual errors or an individual error's display won't make the total output much shorter.

Another option we can consider is to collapse all the errors except the first into a single line such as "Click to see XX additional errors". Ideally, we might want to make sure we only hide errors that are derivative from the root problem. I suspect it's not very easy to do.
