Flutter align a single child in row

Question

I have a Column that has array of rows and each row has some container inside. Here is my code:

import 'package:flutter/material.dart';

Widget row() {
  return Row(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: [
      Container(
        color: Colors.amber,
        width: 50,
        height: 100,
      ),
      Container(
        color: Colors.amber,
        width: 50,
        height: 150,
      ),
      Container(
        color: Colors.blue,
        width: 50,
        height: 80,
      ),
    ],
  );
}

class TestPage extends StatelessWidget {
  const TestPage({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        row(),
        Divider(),
        row(),
        Divider(),
        row(),
      ],
    );
  }
}

Output:

I want to align blue containers to the bottom, without touching other containers position. How can I do that? This my expected result:
