reconfigureInput method
Reconfigures the line as input 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.
You can't specify triggers here because of platform limitations.
Implementation
void reconfigureInput({Bias? bias, ActiveState activeState = ActiveState.high}) {
ArgumentError.checkNotNull(activeState, "activeState");
_checkSupportsBiasValue(bias);
_checkSupportsLineReconfiguration();
// we only change the info, not the ownership
_info = null;
_value = null;
if (!_requested) {
throw StateError("Can't reconfigured line because it is not requested.");
}
PlatformInterface.instance.reconfigureLine(
lineHandle: _lineHandle,
direction: LineDirection.input,
bias: bias,
activeState: activeState,
);
_info = PlatformInterface.instance.getLineInfo(_lineHandle);
