[BUG] [Android] Unable to debug headless background fetch events

[gitboss]

Plugin version: 0.2.0
Platform: Android

Steps to reproduce the behavior:

1. Run the example app in emulator from VS Code.

2. Execute the following in Windows 10 command prompt cmd :
   adb shell am broadcast -a com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample.event.BACKGROUND_FETCH

3. Output :
   Broadcasting: Intent { act=com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample.event.BACKGROUND_FETCH flg=0x400000 }
   Broadcast completed: result=0

4. However the event is neither logged by the example app in the emulator nor can we debug the code.

Note: Simulating the following other event works as expected -
"adb shell cmd jobscheduler run -f com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample 999"

That's right. For devices run Android 21+, fetch uses the modern JobScheduler mechanism, ie:

adb shell cmd jobscheduler run -f com.transistorsoft.flutter.backgroundfetch.backgroundfetchexample 999"

For all older device, it uses AlarmManager, ie:

adb shell am broadcast -a ...

The plugin uses one or the other, not both.
