setAutomaticShutoffTime method
setAutomaticShutoffTime() asynchronously sets the automatic shutdown time of the printer in minutes and returns a Boolean value afterwards with the result of the setAutomaticShutoffTime operation (i.e. success or failure).
Implementation
@override
Future<bool?> setAutomaticShutoffTime(int minutes) async {
var sendMap = <String, dynamic>{"minutes": minutes};
bool? setResult = await methodChannel.invokeMethod<bool>(
'setAutomaticShutoffTime', sendMap);
return setResult;
}
