I'm trying to change the color of the system status bar to black.
The configuration seems to be overridden by the AppBar class. I can achieve what I want by assigning the theme: to ThemeData.dark() when creating the Material App, and then specifying an appBar attribute. But I don't want an AppBar, and also, doing it this way changes all the font colors.
A possible solution is to inherit ThemeData.bright() into a new class, then add something that only changes the system status bar through
setSystemUIOverlayStyle
And then I would need to specify AppBar and make it invisible somehow?

Widget _buildSuggestions() {
return new ListView.builder(
padding: const EdgeInsets.all(16.0),
// The item builder callback is called once per suggested word pairing,
// and places each suggestion into a ListTile row.
// For even rows, the function adds a ListTile row for the word pairing.
// For odd rows, the function adds a Divider widget to visually
// separate the entries. Note that the divider may be difficult

itemBuilder: (context, i) {
// Add a one-pixel-high divider widget before each row in theListView.
if (i.isOdd) return new Divider();
// The syntax "i ~/ 2" divides i by 2 and returns an integer result.
// For example: 1, 2, 3, 4, 5 becomes 0, 1, 1, 2, 2.
// This calculates the actual number of word pairings in the ListView,
// minus the divider widgets.
final index = i ~/ 2;
// If you've reached the end of the available word pairings...
if (index >= _suggestions.length) {
// ...then generate 10 more and add them to the suggestions list.
