Future<AndroidBatteryInfo?>' can't be assigned to the parameter type 'Future<AndroidBatteryInfo>?'

Hi

I installed the package and created an example same as the package, I got this error.

Running Gradle task 'assembleDebug'...
lib/main.dart:26:47: Error: The argument type 'Future<AndroidBatteryInfo?>' can't be assigned to the parameter type 'Future?' because 'AndroidBatteryInfo?' is nullable and 'AndroidBatteryInfo' isn't.

• 'Future' is from 'dart:async'.

Hi,

The example is out of date. The package has recently moved to null-safety.
You should be able to fix the issue by changing FutureBuilder to FutureBuilder<AndroidBatteryInfo?> here:
https://github.com/igrik12/battery_info/blob/master/example/lib/main.dart#L22

The same should work for StreamBuilder.

I will update the example project to reflect the null-safety changes

The example for StreamBuilder hasn't been updated yet
