Fix: Closing bottom sheet and removing FAB cause assertion failure #128566
Conversation
Thanks for fixing this! @utisam We'll need a test for this fix. |
@TahaTesser Test was added at 02404bc The assertion failure was caused on the latest master channel. |
setState(() => show = false); | ||
|
||
await tester.pump(); // start animation | ||
await tester.pump(const Duration(seconds: 1)); | ||
|
||
expect(controller?.closed, completes); | ||
expect(find.byType(FloatingActionButton), findsNothing); |

I'm not really sure if this is the correct way to test this.
When I comment on these lines and just let pumpWidget
, I get errors.
// setState(() => show = false);
// await tester.pump(); // start animation
// await tester.pump(const Duration(seconds: 1));
// expect(controller?.closed, completes);
// expect(find.byType(FloatingActionButton), findsNothing);
return MaterialApp( | ||
home: Scaffold( | ||
body: Builder(builder: (BuildContext context) { | ||
WidgetsBinding.instance.addPostFrameCallback((_) { |

Is addPostFrameCallback
necessary?
It'd be preferable to add and remove the bottom sheet by pressing buttons.

Yeah, maybe can the FAB.onPressed trigger this change?

Thanks for the comments. I rewrite the test using buttons.

I also tried to trigger 2 changes at FAB.onPressed at once, but it does not reproduce the assertion error.
While rewriting the test, I found the problem is only that while the hiding FAB animation is running, another event starts the closing bottom animation. The reversed order (close bottom sheet → hide FAB) or both at once does not.

Thanks for raising this @TahaTesser. Welcome @utisam! Thanks for contributing!
Can you take a look at the test suggestion below? It may be that we just need a bit more context to understand the design of the test - thank you for including one by the way. :)

Just a couple of style guide nits from me, which I was able to just tweak here on github. Thanks again for contributing @utisam! LGTM!
