Visual bug in PieChart when sections values are 0 except for one section

[Herve-D]

Describe the bug
Hello, there seems to be a bug with PieChart, when only one SectionData has a value different than 0, and all others section have a value of 0. It's noticeable with the badges.
Let me know if I'm not clear enough, or if I just don't understand what's wrong here...

To Reproduce

import 'package:fl_chart/fl_chart.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Tests',
      home: Home(),
    );
  }
}

class Home extends StatefulWidget {
  @override
  _HomeState createState() => _HomeState();
}

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Column(
        children: [
          AspectRatio(
            aspectRatio: 1,
            child: PieChart(PieChartData(
                startDegreeOffset: 270,
                sectionsSpace: 5,
                sections: [
                  PieChartSectionData(
                      value: 25,
                      color: Colors.blue,
                      radius: 100,
                      badgeWidget: Container(
                        decoration: BoxDecoration(
                          shape: BoxShape.circle,
                          border: Border.all(color: Colors.red),
                        ),
                        padding: EdgeInsets.all(5),
                        child: Icon(Icons.ac_unit),
                      ),
                      badgePositionPercentageOffset: 1),
                  PieChartSectionData(
                      value: 0,
                      color: Colors.orange,
                      radius: 100,
                      badgeWidget: Container(
                        decoration: BoxDecoration(
                          shape: BoxShape.circle,
                          border: Border.all(color: Colors.red),
                        ),
                        padding: EdgeInsets.all(5),
                        child: Icon(Icons.access_alarm),
                      ),
                      badgePositionPercentageOffset: 1),
                ])),
          ),
        ],
      ),
    );
  }
}

Screenshots

With values non 0, badges are good.

With only one value non 0 (as example in code), badges are off.
