torchLevel method
The current torch brightness level.
The value of this property is a floating-point number whose value is in the range 0.0 to 1.0. A torch level of 0.0 indicates that the torch is off. A torch level of 1.0 represents the theoretical maximum value, although the actual maximum value may be lower if the device is currently overheated.
Implementation
Future<double> torchLevel() async {
return await _channel.$torchLevel(this) as double;
}
