Will the IMEI you obtain occasionally change

1.2.0 deprecated API Android V2 embedding

can you fix that?

The plugin `imei_plugin` uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

persistence of Unique ID of ios device

1. Will Unique ID of ios device remains the same even after the following :
   -factory reset,
   -Backup restore,
   -OS update
   -restart

2. Is there any situation where this unique ID will change?

Thanks,
Gaurav

This plugin is bullshitting us

If you're in Android P and above, it will never return the IMEI. So far the only reason I knew is you gonna get this

PlatformException: The user ***** does not meet the requirements to access device identifiers

And it's the only reason I got here. But this crap plugin instead generate a random UUID from UUID.randomUUID() and store in into shared preferences like it is exactly the unique id for the phone. What's your point for doing that LIAR !!!???

Plugin blocks response of permission_handler plugin

Hello,
I tried your plugin, but somehow your plugin blocks result of permission_handler (and maybe some other plugin).
I reproduced this issue on Android.
To reproduce the issue:

• download permission_handler
• include your plugin in pub.xml
• start android example of permission_handler
• invoke permission request and notice that code after the return is never performed...

Note:device_id: 0.2.0 works just fine with plugin permission_handler

Null Safety

Any predictions for "Null Safety" support?

Force-close application when first asking permission

I have tested your package and it works only on Android version 10. In version 6 (M), the application always forces close when first asking the user to give READ_PHONE access.
I haven't tried other versions except those I have mentioned above

I still can't get IMEI in android 10, could you help me?

Request permissions - Reply already submitted

On Android the onMethodCall is called two times in a row, without waiting for the user's response. When the user allow the permission, the App crash
