getWidget method

Widget getWidget(BuildContext context)

Returns the Flutter widget used to display and edit this property.

The default implementation renders a Text with the current value of the property on the first owner, or an empty string when:

• no owners are present,
• the property is not found, or
• values differ across multiple owners (mixed-value state).

Subclasses should override this to return an interactive editor widget.

Implementation

Widget getWidget(BuildContext context) {
  String value = '';

  if (owners.isNotEmpty) {
    var owner = owners[0];
    var property = owner.getProperty(propertyName);
    if (property != null) {
      value = property.getValue(owner).toString();
    }

    for (int a = 1; a < owners.length; a++) {
      var owner = owners[a];
      var property = owner.getProperty(propertyName);
      if (property == null) {
        value = '';
      } else if (property.getValue(owner) != value) {
        value = '';
      }
    }
  }

  return Text(key: key, value);
}
