Steps to Reproduce

1. Execute flutter run on the code sample
2. Look at the screen

Expected results:

Since the source image has a wider aspect ratio than the BoxDecoration, and fitWidth is used in combination with repeatY, I would expect the image to be repeated vertically, like this:

Actual results:

Instead the image is drawn only once:

(Note that if BoxFit.fitWidth is changed to BoxFit.contain, then I get the expected behaviour in this example. But BoxFit.contain only fits the width if the source image has a wider aspect ratio than the BoxDecoration; I want to fit the width regardless of the aspect ratios).

A similar problem exists between fitHeight and repeatX (though to see it you'll have to modify the aspect ratios in my example program).

import 'package:flutter/material.dart';

void main() {
  runApp(
    FittedBox(
      child: Container(
        width: 100,
        height: 200,
        decoration: const BoxDecoration(
          color: Colors.white,
          image: DecorationImage(
            image: NetworkImage(
                'https://docs.flutter.dev/assets/images/shared/brand/flutter/logo/flutter-lockup.png'),
            fit: BoxFit.fitWidth,
            repeat: ImageRepeat.repeatY,
          ),
        ),
      ),
    ),
  );
}
