Flutter 图像BoxFit.cover未正确应用

我试图用以下代码将整个屏幕填充为4个大小相等的图像（2x2）：

import 'package:flutter/material.dart';

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

class _MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Column(
          children: [
            Expanded(
              child: Row(
                children: [
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                    ),
                  ),
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                    ),
                  ),
                ],
              ),
            ),
            Expanded(
              child: Row(
                children: [
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                    ),
                  ),
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                    ),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

然而，结果是：

如何修复代码来执行此操作？因此，每个图像的大小与其他图像相同，视图为2X2

您可以使用

高度：double.infinity

应用每个图像，以使图像具有尽可能多的高度：

import 'package:flutter/material.dart';

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

class _MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: Column(
          children: [
            Expanded(
              child: Row(
                children: [
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                      height: double.infinity,
                    ),
                  ),
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                      height: double.infinity,
                    ),
                  ),
                ],
              ),
            ),
            Expanded(
              child: Row(
                children: [
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                      height: double.infinity,
                    ),
                  ),
                  Expanded(
                    child: Image.network(
                      'https://static01.nyt.com/images/2020/06/30/business/30india-tech-1/30india-tech-1-articleLarge.jpg?quality=75&auto=webp&disable=upscale',
                      fit: BoxFit.cover,
                      height: double.infinity,
                    ),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    );
  }
}

在fit属性中，使用：

fit:BoxFit.fitHeight，
