ListTile "leading" parameter stopped working

[brian-dunn]

Before the update, I had a ListView with a set of ListTiles that rendered an image on the left side of each tile with the "leading" parameter and a title on the right using the "title" parameter. Now, the image is stretched across the entire tile, and the title value is not displayed on the screen.

Steps to Reproduce

Here is my code. The products variable contains a list of maps with the following structure:
"image" : (name of image file in assets folder)
"title": title of item

import 'package:flutter/material.dart';

class ProductListPage extends StatelessWidget{

final List<Map<String, dynamic>> products;

ProductListPage (this.products);

@OverRide
Widget build(BuildContext context) {
return ListView.builder(
itemBuilder: (BuildContext context, int index) {
return ListTile(
leading: Image.asset(products[index]['image']),
title: Text(products[index]['title']),
// title: Text('test')
);
},
itemCount: products.length,
);
}
}
Attached screen shots show how the program ran before and after the version 1.2 upgrade.

The screen that shows the big image and no title is after upgrading to version 1.2. The screen with the missing title and the stretched out image is how it looks after upgrading to version 1.2. There are no differences in the app source code.

This seems to be the result of #17496. I've noticed two behaviors:

1. If the leading widget's height is too tall with an appropriate width, the widgets seem to stretch vertically beyond the vertical boundaries of the ListTile.

2. There are no horizontal limits for the leading widget. This causes the ListTile widget to stretch vertically only if the title/subtitle text starts to wrap, which occurs regardless of whether there is a leading widget.

I think something could be done to limit the height of the leading widget to prevent the first case from happening, since we want to maintain the look for ListTiles having a fixed height. However, the width should remain flexible and it should be up to the developer to ensure that the title and subtitle fits within the screens and doesn't wrap around.

Just noticed that the same behavior also affects trailing widgets.
