acquire method

@override Future<PowerAssertionHandle> acquire(PowerAssertionOptions options)

Starts holding an assertion with options; throws when the helper cannot be spawned (the caller warns and continues).

Implementation

@override
Future<PowerAssertionHandle> acquire(PowerAssertionOptions options) async {
  final arguments = caffeinateArguments(options, pid: pid);
  final process = await _launcher('caffeinate', arguments);
  return ProcessPowerAssertionHandle(
    process: process,
    description: 'caffeinate ${arguments.join(' ')}',
  );
}
