requestIgnoreBatteryOptimizations method

Future<bool> requestIgnoreBatteryOptimizations(
  1. {bool requestIfDenied = true}

Requests for app to be excluded from battery optimizations to aid running a background process

Only available on Android devices, due to limitations with other operating systems.

Background downloading is complicated: see the documentation website for more information.

If requestIfDenied is true (default), and the permission has not been granted, an intrusive system dialog/screen will be displayed. If false, this method will only check whether it has been granted or not.

Will return true if permission was granted, false if the permission was denied.
