The new project runs abnormally in debug mode.

[592116366]

Here's how I use it： return Container( width: double.infinity, //swiper高度由父组件决定 child: AspectRatio( aspectRatio: 16 / 9, child: Swiper( itemBuilder: (BuildContext context, int index) { return Image.network( imageList[index]["url"], fit: BoxFit.fill, ); }, autoplay: true, itemCount: imageList.length, //分页指示器 pagination: const SwiperPagination(), control: const SwiperControl(color: Colors.orange), ), ), );

The running time is variable maybe 1 minute。Throwing an exception，The information is as follows：

════════ Exception caught by scheduler library ═════════════════════════════════ The following assertion was thrown during a scheduler callback: 'package:flutter/src/animation/animation_controller.dart': Failed assertion: line 829 pos 12: 'elapsedInSeconds >= 0.0': is not true.

When the exception was thrown, this was the stack

2 AnimationController._tick

package:flutter/…/animation/animation_controller.dart:829

3 Ticker._tick

package:flutter/…/scheduler/ticker.dart:249

4 SchedulerBinding._invokeFrameCallback

package:flutter/…/scheduler/binding.dart:1175

5 SchedulerBinding.handleBeginFrame.

package:flutter/…/scheduler/binding.dart:1079

6 _LinkedHashMapMixin.forEach (dart:collection-patch/compact_hash.dart:617:13)

7 SchedulerBinding.handleBeginFrame

10 PlatformDispatcher._beginFrame (dart:ui/platform_dispatcher.dart:296:5)

11 _beginFrame (dart:ui/hooks.dart:104:31)

(elided 2 frames from class _AssertionError)

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

2 SchedulerBinding.scheduleFrameCallback

package:flutter/…/scheduler/binding.dart:538

3 Ticker.scheduleTick

package:flutter/…/scheduler/ticker.dart:265

4 Ticker.start

package:flutter/…/scheduler/ticker.dart:171

5 AnimationController._startSimulation

package:flutter/…/animation/animation_controller.dart:752

6 AnimationController._animateToInternal

package:flutter/…/animation/animation_controller.dart:619

7 AnimationController.animateTo

package:flutter/…/animation/animation_controller.dart:538

Hope it can be repaired！thanks!

I also encountered this problem, I was using Android 7, and it was no problem to switch to Android 9. Might be an issue with the Android version or the emulator.
