0 _ArrowElementState.initState (package:widget_arrows/widget_arrows.dart:333:73)

1 StatefulElement._firstBuild (package:flutter/src/widgets/framework.dart:5015:57)

2 ComponentElement.mount (package:flutter/src/widgets/framework.dart:4853:5)

3 Element.inflateWidget (package:flutter/src/widgets/framework.dart:3863:16)

4 MultiChildRenderObjectElement.inflateWidget (package:flutter/src/widgets/framework.dart:6435:36)
