merge method
Merges new data into the current scope.
This method takes a map of new data and merges it into the current scope. If a variable with the same name already exists in the current scope, its value will be overwritten with the new value.
newData

Implementation
void merge(Map<String, dynamic> newData) {
newData.forEach((key, value) {
setVariable(key, value);
});
}
