}

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Another Dashed Container Example'),
        ),
        body: Center(
          child: AnotherDashedContainer(
            dashColor: Colors.blue,
            strokeWidth: 2.0,
            dashLength: 10.0,
            dashSpace: 5.0,
            borderRadius: 10.0,
            child: Container(
              width: 200,
              height: 200,
              alignment: Alignment.center,
              child: Text(
                'Dashed Container',
                style: TextStyle(fontSize: 20),
