Assertion Error on device with 120hz refresh rate "The following assertion was thrown during a scheduler callback: 'elapsedInSeconds >= 0.0': is not true." #106277
Description
Summary as of 2024-08:
- The issue appears on a wide range of devices and platforms, but only with a refresh rate of 120 Hz or greater. (Assertion Error on device with 120hz refresh rate "The following assertion was thrown during a scheduler callback: 'elapsedInSeconds >= 0.0': is not true." #106277 (comment))
- The impact of this issue is in debug builds only, but it's severe there: the app crashes, making it impossible to continue short of a restart. For apps where the issue triggers frequently, this can make it difficult to develop on a device with a ≥120 Hz refresh rate.
- Thumbs-up this issue if you run into it
Original report follows.
I have an issue that only arises on my S22 Ultra. It does not occur within Android emulator, iPhone simulator, or a physical iPhone X. I only have one physical android device to test on.
The issue is unpredictable, but usually occurs after tapping something with an InkWell. It occurs throughout my app. However, I believe the issue to be related to animations. While it usually occurs after tapping an InkWell, it also can occur doing any other animation, such as the animation closing a ModalBottomSheet.
Recreating the issue is challenging, as it is insanely unpredictable. I'll sit and tap on a few buttons with InkWell's repeatedly, trying to get the issue to arise... And nothing. Then I'll go about using my app... And the error will pop-up. It has been going on for nearly a month.
It can occur shortly after launch, or well into testing features.
After closing a modalBottomSheet:
