I would like to detect whether the device (Android and ios) has been previously rebooted before opening the apps. I noticed that there would be many possible ways to achieve it if we could rely on the device clock's time like what has been elaborated here. My concern would be; the device clock can be changed, and the apps can work in offline mode.
Android
My idea would be to store a boolean variable using Android SharedPreferences after device has been rebooted, and set as true. Then check the variable after user opens the apps. If true, then we can confirm that the device is previously rebooted, else not.
ios
I have no idea on how to implement it for ios, but the link above might gives me a hint.
Solution that might works in both platform (not try yet)
If RAM usage cleared after device restart, then I would assume that if RAM usage is on certain level,the device has been rebooted.
Of all the possible ways to achieve the objective, I would prefer to use existing package. But I would happy if you can give your feedbacks for the above ideas.
So my questions would be :
I hate to reinvent the wheel, so any existing Flutter package or any other library which can't be found on https://pub.dev/packages that can be used to detect whether the device has been previously rebooted before opening the apps?
Is there any other possible solution that I missed which already have in Flutter architecture to solve the issue?
Update
I've found a package called boot_completed which only supported on Android.
..and I've found an interesting feature for Android running API level 24 BOOT_COUNT. Horray!
