/// onScreenshotcan be used to process the screenshots taken during the test. /// An example could be that this callback compares the byte array against a baseline image, /// and it returnstrueif both images are equal. /// /// As a result, returningfalsefromonScreenshot will make the test fail.

Но в flutter/ packages/integration_test/lib/integration_test_driver_extended.dart есть обратный вызов onScreenshot(), но нет параметра responseDataCallback(): хотя в обоих случаях он возвращает null после выполнения всего тестового примера. Как сделать снимок экрана с помощью пакета flutter/packages/integration_test/lib/integration_test_driver.dart, если он не содержит обратного вызова onScreenshot()?

У него есть. Вы можете использовать так:

 import 'dart:io';

import 'package:flutter_driver/flutter_driver.dart';
import 'package:integration_test/integration_test_driver_extended.dart';

Future<void> main() async {
  final FlutterDriver driver = await FlutterDriver.connect();
  await integrationDriver(
    driver: driver,
    onScreenshot: (String screenshotName, List<int> screenshotBytes) async {
      final File image = File('screenshots/$screenshotName.png');
      image.writeAsBytesSync(screenshotBytes);
      // Return false if the screenshot is invalid.
      return true;
    },
  );
}
 

Вам нужно использовать пакет ‘import’:integration_test/integration_test_driver_extended.dart’import.
