LineChartBarData crash if shadow applied on iOS #1466

joselicht90 · 2023-10-24T17:40:11Z

Describe the bug
I've found that if I applied a Shadow to LineChartBarData that only has one FlSpot, the app will crash. This didn't happened to me before upgrading to latest flutter and lates package version.

To Reproduce

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Center(
        child: LineChart(
          LineChartData(
            borderData: FlBorderData(
              show: false,
            ),
            minX: 0,
            maxX: 7,
            minY: -15,
            maxY: 100,
            lineTouchData: LineTouchData(
              getTouchedSpotIndicator: (barData, spotIndexes) {
                return spotIndexes.map((spotIndex) {
                  const color = Colors.red;
                  return const TouchedSpotIndicatorData(
                    FlLine(
                      color: color,
                      dashArray: [5, 10],
                      strokeWidth: 2,
                    ),
                    FlDotData(
                      show: true,
                    ),
                  );
                }).toList();
              },
            ),
            lineBarsData: [
              LineChartBarData(
                spots: [
                  FlSpot(2, 50),
                ],
                isCurved: true,
                shadow: Shadow(
                  color: Colors.black.withOpacity(0.55),
                  offset: const Offset(0, 5),
                  blurRadius: 4,
                ),
                color: Colors.red,
                barWidth: 4,
                isStrokeCapRound: false,
                show: true,
                curveSmoothness: 0,
                dotData: FlDotData(
                  show: true,
                  getDotPainter: (p0, p1, p2, p3) {
                    return FlDotCirclePainter(
                      radius: 6,
                      color: Colors.black,
                      strokeWidth: 2,
                      strokeColor: Colors.red,
                    );
                  },
                ),
              ),
            ],
          ),
        ),
      ),
    );
  }
}
