reconfigureOutput method
void
reconfigureOutput({
- OutputMode outputMode = OutputMode.pushPull,
- Bias? bias,
- ActiveState activeState = ActiveState.high,
- required bool initialValue,
Reconfigures the line as output with the given configuration.
If FlutterGpiod.supportsBias is false, bias
must be null
,
otherwise a UnsupportedError will be thrown.
This will throw a UnsupportedError if FlutterGpiod.supportsLineReconfiguration is false.
