1. Run flutter create bug.

2. Update the files as follows:
   Just added TextStyle:

Text(
   'You have pushed the button this many times:',
   style: TextStyle(
      color: Colors.white,
      backgroundColor: Colors.yellow,
   ),
),

3. Problem
   The problem happens with Flutter Web:

color applies a color to the text. But if a backgroundColor is added as well, then color is not applied anymore.

Expected results: White text on yellow background

Actual results: Black text on yellow background
