'!_debugDisposed': is not true

[zhang david]

I write a simple SfRadialGauge test app with changable pointers, after change Pointer's type several times, for example ,change pointer type to marker pointer ,then change to range pointer, then change back to marker pointer, then I've got an error as following,

The following assertion was thrown during performLayout():

'package:flutter/src/rendering/object.dart': Failed assertion: line 2067 pos 12: '!_debugDisposed':

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.md

The relevant error-causing widget was:

  RadialAxisParentWidget

  RadialAxisParentWidget:file:///home/py/.pub-cache/hosted/pub.flutter-io.cn/syncfusion_flutter_gauges-21.1.35/lib/src/radial_gauge/axis/radial_axis.dart:1178:14

I attach to this post my flutter code, anyone help will be appreciated！
