error message shows up sometime

[agsrules99]

This error message shows up sometime when I use the avataaars. I can't figure out how to solve this, sometimes it pops up, sometimes it's fine. I think there is something wrong with the package.

The following NoSuchMethodError was thrown building AvataaarImage(dirty): flutter: The getter 'pieceEntries' was called on null. flutter: Receiver: null flutter: Tried calling: pieceEntries flutter: flutter: When the exception was thrown, this was the stack: flutter: #0 Object.noSuchMethod (dart:core-patch/object_patch.dart:50:5) flutter: #1 _AvataaarImage&StatelessWidget&AvataaarsApi.getUrl (package:avataaar_image/src/image.dart:47:27) flutter: #2 AvataaarImage.build (package:avataaar_image/src/image.dart:32:22) flutter: #3 StatelessElement.build (package:flutter/src/widgets/framework.dart:3789:28) flutter: #4 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:3739:15) flutter: #5 Element.rebuild (package:flutter/src/widgets/framework.dart:3565:5) flutter: #6 ComponentElement._firstBuild (package:flutter/src/widgets/framework.dart:3722:5) flutter: #7 ComponentElement.mount (package:flutter/src/widgets/framework.dart:3717:5) flutter: #8 Element.inflateWidget (package:flutter/src/widgets/framework.dart:2961:14) flutter: #9 Element.updateChild (package:flutter/src/widgets/framework.dart:2764:12) flutter: #10 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:3750:16) flutter: #11 Element.rebuild (package:flutter/src/widgets/framework.dart:3565:5) flutter: #12 BuildOwner.buildScope (package:flutter/src/widgets/framework.dart:2278:33) flutter: #13 _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding&PaintingBinding&SemanticsBinding&RendererBinding&WidgetsBinding.drawFrame (package:flutter/src/widgets/binding.dart:700:20) flutter: #14 _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding&PaintingBinding&SemanticsBinding&RendererBinding._handlePersistentFrameCallback (package:flutter/src/rendering/binding.dart:286:5) flutter: #15 _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding._invokeFrameCallback (package:flutter/src/scheduler/binding.dart:1012:15) flutter: #16 _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding.handleDrawFrame (package:flutter/src/scheduler/binding.dart:952:9) flutter: #17 _WidgetsFlutterBinding&BindingBase&GestureBinding&ServicesBinding&SchedulerBinding._handleDrawFrame (package:flutter/src/scheduler/binding.dart:864:5) flutter: #21 _invoke (dart:ui/hooks.dart:219:10) flutter: #22 _drawFrame (dart:ui/hooks.dart:178:3) flutter: (elided 3 frames from package dart:async) flutter: ════════════════════════════════════════════════════════════════════════════════════════════════════ flutter: Another exception was thrown: NoSuchMethodError: The getter 'pieceEntries' was called on null. flutter: Another exception was thrown: NoSuchMethodError: The getter 'pieceEntries' was called on null. flutter: Another exception was thrown: NoSuchMethodError: The getter 'pieceEntries' was called on null
