[ Android ] Multiple camera widgets issue #25

Closed intellitour closed 4 years ago

intellitour commented 4 years ago

In Android, when you put multiple pages (navigate from one page to another). each with AdvCamera, in the second one there will be a blank screen instead of the preview.

I believe this is related to: https://github.com/ricnaaru/adv_camera/issues/22

Let me check it

I managed to catch the error log:

Thanks!

ricnaaru commented 4 years ago

Sorry this take a long time, i've looked into it, and since it's been quite a long time since I do Android and Fragment, i couldn't get this fixed. It seems like somehow it will become nested Fragment. So, probably I will look into this more, if I have some spare time. Sorry.

@ricnaaru by closing you mean fixed or won't fix?

benneca commented 2 years ago

This is still an issue, is there a workaround for this? I have this issue, not because of multiple screens with cameras, but rather the first screen (default) is the camera. Due to the dart bug where the initial screen does not call the dispose method, I continually run into the issue above. I have attempted to combat this by trying to use pushreplacenamed on the first item in the stack if the route is the camera screen, this forces the dispose method. However on subsequent page visits, if I want to allow the user to use the back stack, this is not a fully reliable solution. If there were simply a method to check if the camera is already initialized and then resume or dispose of it at that point, this could be resolved.
