Rx<T> globalWatch<T>(T v, { Object? tag, })

Create a watched variable from the variable v, a proxy object of the Type of Rx<T>

Implementation

Rx<T> globalWatch<T>(T v, {Object? tag}) {

        print('Info: Global watched variable of Type: $T already exists.');
        print(
            'If the watched variable would be used across files, please use the [tag] parameter.');
        return true;
      }());
    }
