What is latest mater? Is it better than stable version? Because it seems to me. Stable has bug but master hasn't. Can you guide me to upgrade to latest master version? |
|
Hi @maheshkumar2150 If you decide to upgrade please follow the docs |
|
There is no way to use it in stable? |
|
It is working as expected in Android but in iOS, can anyone verify that it is working in master channel in iOS platform? I am using |
|
tagging @pedromassango for visibility |
|
I know this is separate issue working properly in Android |
|
I tested this and here is my feedback Pressed overview button and closed the app by swiping (master channel)Closed the app by pressing the back button (master channel)Pressed overview button and closed the app by swiping (stable channel)Closed the app by pressing the back button (stable channel)The issueIf you press the overview button and closed the app by swiping quickly, then the only method getting called it So this is still valid. flutter doctor -v (stable)flutter doctor -v (master) |
|
I have the same issue, I tested it in to physical phones -Samsung j7 prime with android 8: I think it depends on the android version |
|
I've tested this on iOS Simulators and an iPhone 6 running iOS 12 and |
|
I have the same issue. Any updates? |
|
@haroonkhan9426 |
|
Any update on this? Or is there any other way in Flutter to execute a code(say calling a REST API) just before the app is swiped off(detached)? |

AppLifecycleState.Detached was not printed.
Nothing was saved in database in my real app.
But if i close the app by pressing the back button,
WillPopScore is handling the back button press.
So when the user closed app with overview button, i want to store the last activity in database and i want to resume it when the app opens again.
I am making an app for android and ios.
The above code was tested with android in windows.
The text was updated successfully, but these errors were encountered:
