# onLocaleChanged property

VoidCallback onLocaleChanged

A callback that is invoked whenever locale changes value.

The framework invokes this callback in the same zone in which the callback was set.

See also:

- `WidgetsBindingObserver`, for a mechanism at the widgets layer to observe when this callback is invoked.

## Implementation

    VoidCallback get onLocaleChanged => _onLocaleChanged;

void onLocaleChanged= (VoidCallback callback)

## Implementation

    set onLocaleChanged(VoidCallback callback) {
      _onLocaleChanged = callback;
      _onLocaleChangedZone = Zone.current;
    }
