setValue method

void setValue(
  1. String key,
  2. Object value, {
  3. Object? converterParameter,
})

Sets a value back into the BindableBase object.

This uses the key that was set up with the binding. Additionally a converterParameter can be passed that will be send to a value converter if supplied with the binding. The value is the new value to set into the property specified by the binding.

Implementation

void setValue(String key, Object value, {Object? converterParameter}) {
  Binding binding = _getBinding(key);
  if (binding.valueConverter == null) {
    binding.source.setValue(binding.sourceProperty, value);
  } else {
    binding.source.setValue(
        binding.sourceProperty,
        binding.valueConverter!.convertBack(binding.source, value,
            parameter: converterParameter));
  }
}
