I couldn't reproduce it.
Can you please share a reproducible code? (a main.dart file content)

[islavstan]

your have to add centerSpaceRadius
and increase PieChart size
I changed your sample, here is example

import 'package:fl_chart_app/presentation/resources/app_resources.dart';
import 'package:fl_chart_app/presentation/widgets/indicator.dart';
import 'package:fl_chart/fl_chart.dart';
import 'package:flutter/material.dart';

class PieChartSample1 extends StatefulWidget {
  const PieChartSample1({super.key});

  @override
  State<StatefulWidget> createState() => PieChartSample1State();
}

class PieChartSample1State extends State {
  int touchedIndex = -1;

  @override
  Widget build(BuildContext context) {
    return SizedBox(
      height: 300,
      width: 300,
      child: PieChart(
        PieChartData(
          pieTouchData: PieTouchData(
            touchCallback: (FlTouchEvent event, pieTouchResponse) {
              setState(() {
                if (!event.isInterestedForInteractions ||
                    pieTouchResponse == null ||
                    pieTouchResponse.touchedSection == null) {
                  touchedIndex = -1;
                  return;
                }
                touchedIndex = pieTouchResponse
                    .touchedSection!.touchedSectionIndex;
              });
            },
          ),

          borderData: FlBorderData(
            show: false,
          ),
          sectionsSpace: 0,
          centerSpaceRadius: 80,
          sections: showingSections(),
        ),
      ),
    );
  }

  List<PieChartSectionData> showingSections() {
    return [
      PieChartSectionData(
        color:  AppColors.contentColorBlue,
        value: 100,
        title: '',
        radius: 80,
        titlePositionPercentageOffset: 0.55,
        borderSide: BorderSide(
            color: AppColors.contentColorWhite.withOpacity(0)),
      )
    ];
  }
}

I think problem in PieChartPainter
if (sectionDegree == 360) {
_sectionPaint
..color = section.color
..strokeWidth = section.radius
..style = PaintingStyle.stroke;
canvasWrapper.drawCircle(
center,
centerRadius + section.radius / 2,
_sectionPaint,
);
