[BUG] Failed assertion: line 822 pos 12: 'elapsedInSeconds >= 0.0': is not true.

What is the bug?

This bug appears randomly it seems. Here was my full error:

EXCEPTION CAUGHT BY SCHEDULER LIBRARY
The following assertion was thrown during a scheduler callback:
'package:flutter/src/animation/animation_controller.dart': Failed assertion: line 822 pos 12:
'elapsedInSeconds >= 0.0': is not true.

Either the assertion indicates an error in the framework itself, or we should provide substantially
more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
https://github.com/flutter/flutter/issues/new?template=2_bug.yml

When the exception was thrown, this was the stack:
#2 AnimationController._tick (package:flutter/src/animation/animation_controller.dart:822:12)
#3 Ticker._tick (package:flutter/src/scheduler/ticker.dart:249:12)

This exception was thrown in the context of a scheduler callback. When the scheduler callback was registered (as opposed to when the exception was thrown), this was the stack:

Another exception was thrown: 'package:flutter/src/animation/animation_controller.dart': Failed assertion: line 822 pos 12: 'elapsedInSeconds >= 0.0': is not true.
Another exception was thrown: 'package:flutter/src/animation/animation_controller.dart': Failed assertion: line 822 pos 12: 'elapsedInSeconds >= 0.0': is not true.

Later on, as the app runs, it will print out the "Another exception was thrown" many times, sometimes 20+ times. At this point, I am just displaying the flutter map on the screen, and not even interacting. In the background, the app updates data every minute.

How can we reproduce it?

Unfortunately, I do not know how to reproduce the error. I found some other issues for flutter in general on github regarding 'elapsedInSeconds >= 0.0: is not true', but no mention of flutter map. And although it mentions "animation_controller.dart" in the error message, I only have a single animation which I rarely use, and it requires user interaction to even start it.

Do you have a potential solution?

Hi @corepuncher,

Thanks for reporting this, I'll have a quick look to see if there's anything immediately wrong. However, the error log does say to report this issue to the Flutter team in order to add more debugging/resolution to this log, so it's possible I won't find anything.

I know that the logs contain flutter_map, but I would just try to isolate your custom animation, just in case that's interfering somehow for whatever reason.

[corepuncher]

Thank you will do. The weird thing is, I only have 1 small animation (a blinking icon when tapped), very little code, and the error occurs even when I do not interact with it. I will send a report to flutter.

For now, going to close this as an external issue. If it can be reproduced after flutter/flutter#106277 is resolved, then this can be re-opened. Thanks @corepuncher for handling it!
