[编写Flutter小部件测试时，我遇到了一个错误，即在showModalBottomSheet（）期间创建的股票代码未得到处理的错误。
[我想我知道如果我要实现自己的Flutter动画，我应该制作一个AnimationController，并在小部件AnimationController.dispose()方法期间调用dispose。
但是，由于（我相信）将AnimationController抽象化以提供一些便利，所以我不确定在完成测试后在哪里或如何确保将小部件丢弃。
注意：代码可以正常工作，当我在模拟器/模拟器上进行测试时，模态底板很好。我只想能够在testWidgets测试中对其进行测试。
我看过showModalBottomSheet文档https://api.flutter.dev/flutter/material/showModalBottomSheet.html，但这仅显示了如何使用该功能。我没有找到任何方法来控制何时可以处理动画。
（在发生异步问题的情况下，额外的pump()，但似乎没有帮助）
testWidgets('Taping edit score button brings up bottom sheet to edit',
(WidgetTester tester) async {
setUp();
await tester.pumpWidget(MaterialApp(
home: GameList(
game: Game(players: players),
),
));
await tester.tap(find.byKey(Key('p1-edit-score')));
await tester.pump();
await tester.pump();
expect(find.byKey(Key('test')), findsOneWidget);
await tester.tap(find.byKey(Key('tap-me')));
await tester.pump();
await tester.pump();
tearDown();
});
class GameView extends StatefulWidget {
GameView({@required this.playerList, @required this.onResetPlayerScores});
final Function onResetPlayerScores;
final List<Player> playerList;
@override
_GameState createState() => _GameState();
}
class _GameState extends State<GameView> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(...),

为简洁起见删除了一些小部件

flutter test的短输出。我认为最重要的部分。OverlayState created a Ticker via its TickerProviderStateMixin, but at the time dispose() was called
on the mixin, that Ticker was still active. All Tickers must be disposed before calling
super.dispose(). Tickers used by AnimationControllers should be disposed by calling dispose() on the
AnimationController itself. Otherwise, the ticker will leak.
flutter test的完整输出The following assertion was thrown while finalizing the widget tree:
OverlayState#bfe06(tickers: tracking 1 ticker, entries: [OverlayEntry#c26ee(opaque: false;
maintainState: false), OverlayEntry#7cd4f(opaque: false; maintainState: true),
OverlayEntry#d496e(opaque: false; maintainState: false), OverlayEntry#e9ad3(opaque: false;
maintainState: true)]) was disposed with an active Ticker.
