AppLifeCycleState, no constant named suspending

[nyck33]

There's no constant named 'suspending' in 'AppLifecycleState'.
Try correcting the name to the name of an existing constant, or defining a constant named 'suspending'.

counter example main.dart
line 116

///Handle app lifecycle events, almost the same as [update] function
Upd<Model, Message> lifeCycleUpdate(AppLifecycleState appState, Model model) {
  switch (appState) {
    case AppLifecycleState.inactive:
    case AppLifecycleState.paused:
    case AppLifecycleState.suspending:
    //case AppLifecycleState.detached:
      return Upd(model.copyWith(autoIncrement: false));
    case AppLifecycleState.resumed:
    default:
      return Upd(model);
  }
}

I'm going to try replacing suspending with detached but please let me know what you think.

Also in the same counter example main.dart
line 137 or 138

body: Center(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: <Widget>[
          Text(
            '${model.counter}',
            style: Theme.of(context).textTheme.headline1, //display1,
          ),
          Padding(
            child: RaisedButton.icon(
              label: Text('Increment'),
              icon: Icon(Icons.add),
              onPressed:
.
.
.

I guess display1 is outdated so I changed to headline1

@nyck33 Thanks for the bringing it up.
Yes, AppLifecycleState.suspending should be replaced with AppLifecycleState.detached and display1 -> headline1.
Please open a PR if you don't mind.
