QUESTION

Flutter Android release UI render failure

Asked 2021-May-19 at 09:25

I have built a Flutter application using MobX as my state management and am running into a strange issue at the moment that is only present on Android running in release mode.

I'm not sure if the offender is MobX, Hive or just Flutter in Android itself. However, on this specific page in my app, the Obsever will only display the last entry in the list. The other items are present, but the UI will only show the last index of the list. When I turn my phone landscape, the full content of the list is then visible and the page displays exactly as intended. Is there a way I can force the widgets to re-render in MobX when the page has already loaded?

I have tried downgrading my target SDK to 28, downgrading the gradle version, setting shrinkResources & minifyEnabled to false, enabled proguard. I also have ensured to call this in my main.dart;

The solution I found was to generate the list directly from the Hive box using a ValueListenableBuilder to listen to the box and add more elements to the list as soon as they arrive in the box. I can only assume there was some kind of race case going on with MobX attempting to gather the elements in the box from Hive and then serve up to the UI layer. I'll attach some sample code below for anyone else who may run into a similar issue.

Zenject Unity testing scene - how navigate next scene, having container updated to new SceneContext properly?

Asked 2018-Nov-04 at 19:13

How to switch scene during scene test, in a class extending SceneTestFixture?

I need to make a test case while extending SceneTestFixture , where during the test I load Scene 'A' and it set a condition to ProjectContext and then in the same test switch to Scene 'B' and have it to test if the condition is set by 'A', if not to return back to 'A'.

If I try to LoadScene() following the Zenject documentation, then I can't reuse it to switch to next scene. Loading additive is not what I need, so not to use LoadScenes(), and if I use LoadScene() to load 'A', but then by standard Unity SceneManager switch to another scene, then the SceneContainer is Not updated to the new scene and I don't know how to update it. This is an example how my code fails and the flow:

This is an issue with Zenject's SceneTestFixture class. It assumes that the scene will not change at runtime currently. I added an issue for it here. In the meantime, you can get the scene context for the current scene by doing something like this:
