Pie chart swapping data causes render box exception if animation enabled

[shababhsiddique]

I have a simple donut chart with data changed from provider on demand. When I do swap it gives a render exception.

The following assertion was thrown during a scheduler callback:
Updated layout information required for RenderLimitedBox#ebf03 NEEDS-LAYOUT NEEDS-PAINT to calculate
semantics.
'package:flutter/src/rendering/object.dart':
Failed assertion: line 2747 pos 12: '!_needsLayout'

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

When the exception was thrown, this was the stack:

It renders fine visually, but this exception occur very randomly(sometime goes smoothly without exception with same data) when I switch data between income and expense

To Reproduce
Code of the pie chart
` AspectRatio(
aspectRatio: 1,
child: PieChart(
PieChartData(
borderData: FlBorderData(
show: false,
),
sectionsSpace: 0,
centerSpaceRadius: 41,
startDegreeOffset: -90,
sections: _generateSections(),
),
),
),

List _generateSections() {
List piePieces = [];

int index = 0;
for (var pieceInfo in sortedCategoryPieces) {
  final isTouched = index == selectedPieIndex;
  final fontSize = isTouched ? 12.0 : 10.0;
  final radius = isTouched ? 38.0 : 34.0;
  final percentage =
      ((pieceInfo.total / grandTotal) * 100).toStringAsFixed(2);

  piePieces.add(PieChartSectionData(
    color: hexColor(pieceInfo.category.color),
    value: pieceInfo.total + 1,
    showTitle: isTouched,
    title: "$percentage%",
    radius: radius,
    titlePositionPercentageOffset: 1,
    titleStyle: TextStyle(
        fontSize: fontSize,
        fontWeight: FontWeight.w500,
        color: SpenderColors.text,
        backgroundColor: SpenderColors.scaffoldBackground),
  ));
  index++;
}
return piePieces;

}
`

data is from provider

The exception goes away when I set
swapAnimationDuration: Duration.zero,

from my testing it occur often when there is not enough items in the pie (either current or the one that animating from) this seem silly how do I get around this?

[NickJokic]

+1, same

[imaNNeo]

I need a reproducible code to work on it.

[Eliathoran]

This can be reproduced by having a ScaffoldMessenger shown in a stateless widget that has the chart.

As for myself it is happening when I'm rendering the view because of a new state.

Could it be because states change faster than the animation itself? Still happening with a waiting time between states.

@shababhsiddique solutions works, but sadly removes the animation :(

It is a duplicate of #861
I made a fix right now on dev branch.
You need to wait for the next version.

Please follow it in #861.
