                  });
                } on PlatformException catch (error) {
                  if (error.code == BarcodeScanner.CameraAccessDenied) {
                    setState(() {
                      this.barcode =
                          'Izin kamera tidak diizinkan oleh si pengguna';
                    });
                  } else {
                    setState(() {
                      this.barcode = 'Error: $error';
                    });
                  }
                }
              },
            ),
            Text(

Use Split.

for more details https://stackoverflow.com/a/55358328/11794336

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  static const String example = 'abc; def; ghi;';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: ListView(
          children: example
              .split(';')                       // split the text into an array
              .map((String text) => Text(text)) // put the text inside a widget
              .toList(),                        // convert the iterable to a list
        )
      ),
    );
  }
}
