Bug description
Confirmed that this issue only occurs starting in Flutter 3.32.6. The problem does not happen in Flutter 3.32.5
It looks like there is some new rendering logic in 3.32.6 that does not play well with syncfusion_flutter_charts, namely when the chart widget is disposed.
Steps to reproduce
- Create a
SfCircularChart - Build widget
- Dispose the widget (.e.g by navigating to another page)
Code sample
Code sample
SfCircularChart(
series: series,
legend: const Legend(
isVisible: true,
position: LegendPosition.bottom,
iconWidth: 8,
iconHeight: 8,
),
