안녕하세요 막 공부를 시작한 학생입니다. 코드를 받아서 실행해보려했는데 widget_test.dart의 expect(find.text('0'), findsOneWidget);에서 오류가 납니다. 다른 해결법을 검색해봐도 잘 모르겠어서 올려봅니다

widget_test.dart

import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:myApp_frontend/main.dart';

void main() {
  testWidgets('Counter increments smoke test', (WidgetTester tester) async {
    // Build our app and trigger a frame.
    await tester.pumpWidget(const myApp());

    // Verify that our counter starts at 0.
    expect(find.text('0'), findsOneWidget);
    expect(find.text('1'), findsNothing);

    // Tap the '+' icon and trigger a frame.
    await tester.tap(find.byIcon(Icons.add));
    await tester.pump();

    // Verify that our counter has incremented.
    expect(find.text('0'), findsNothing);
    expect(find.text('1'), findsOneWidget);
  });
}

      if (travelLanguage != null) {
        final travelController = Get.put(TravelController());
        travelController.modify(travelLanguage, travelCurrency!);
      }

      Get.off(() => const HomePage());
