double startY

Implementation

double get startY => _startY;
void startY=(double value)

Change the _startY field value. startYChanged will be invoked only if the field's value has changed.

Implementation

set startY(double value) {
  if (_startY == value) {
    return;
  }
  double from = _startY;
  _startY = value;
  if (hasValidated) {
    startYChanged(from, value);
  }
}
