When I invoke BackgroundLocator.registerLocationUpdate() the following exception flies:

E/flutter (25352): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: Failed assertion: boolean expression must not be null
E/flutter (25352): #0      BackgroundLocator.registerLocationUpdate

The boolean autoStop is an optional method parameter. It should either be marked as @required or get a default value.

@komape Thank you for opening an issue.

I saw the issue notification and somehow I managed to forget about it :) Anyway, thanks for your contribution;
